Dnk........Kinda bet that pic is not of someone using a carbon off of a crossbow, unless he a candidate for the Darwin award, "probably" off a compound and you said you use carbons off a compound.Soooo where does that leave you???????...............Once in my shop I had a customer using Nitro Stingers(junk) and the front sight was not tight and slid down, resulting in a collision with the arrow, arrow broke in half the rear half entering the(left) forearm and exited the wrist(sorry no pics) too busy trying to save his life when he took out 4ins of the artery......Wish all my deer bled that bad..........................Still have not answered why Easton does not guarantee their alums to stay straight???????And when was the last time you shot 10 deer with the same arrow??????? There is only "one real arrow " and that is the GOLD TIP(STRAIGHTNESS .001 weight tolerence+or-2grs)

Where does that leave me? Humm guess Darwin wasn't yapping about me because I check my carbons before shooting. I know you didn't think about that so I thought I should let you know. Yes we had one person here have a carbon come apart on the shot from his xbow. Have you ever heard of an aluniunm having the spine shot out of it or coming apart on the shot? Guess not. Nope my last XX78 was as straight as a pin when I destroyed it in a Robin Hood. I don't know of any manufacuterer to guarantee the longevity of their shaft's spine. What toilet did you get that one from and whats with the fetish with keeping track of how many deer you shot with one shaft? I would think a gaget guy like yourself would be quite the opposite. BTW sounds like you are bashing carbons how, might be some bi-polar thing happening here. Sooooooo tell me what difference I'll see between your Gold tip and an XX78 when I wack a deer? Oh thats it my shot will be a thou off center! I have complete confidence in my equipment which you obviously do not. Otherwise you would not grasp at every bit of imagined advantage to attain the confidence level that I already have. Its practically a sin to tell guys like Mike that his hunting is inferior because he cannot or will not afford more expensive equipment. He is superior to you because he is a successfull hunter with basic tools and he enjoys the hunt not the gagetry. Hunting is about the hunt not the equipment and shooting is about breathing, trigger control etc. Yes some knowledge about equipment is important. I own quite a lot of techie junk but I am getting bored with most of it and and I am enjoying the hunt more and more as I get older. I have nothing against you and all your suggestion but I do think some of the others that are just starting should be guided towards learning the basics of hunting and shooting rather than fancy equipment. You sound like you have lots of experience in hunting and shooting, why not help them with the basics?
Jaygail, please don't take my "shots" at you personally. Its all meant in a harmless way. I think its ok to disagree and to agree to disagree.

Mike, Don't worry about it, he's poor in the heart area already. He might learn tho and then we can talk to him at the same level, on earth.

RE: How to figure down range velocity and energy??
 
Dnk,,,My carbons will shoot as good as your alums, but they will last much, much, longer....And of course I test them before shooting...In fact they are not really good for business, my good shooters used to buy app. 2 to 3 dozen alums. from me every year.Now with the carbons they buy app. 1 dozen every two years or longer....You never heard me say that all carbons are created equal(alas the Stinger thru the forearm,and Eastons garbage carbons). And this is something that you were not aware of, Easton produced a bunch of alum. a few years ago that were snapping off at various spots along the tube due to either bad production or bad metal..I had to find out the hard way(another story for another day) I do not trust their business practices(I was told they knew about those failures)..As far as price goes I sell the Gold Tips for the same price as the alums(what nit-wit would buy the alums. after I explained that to them)That mutes one of your arguments...............I fully admit I am not the best "hunter in the world" and how do we judge that,by how full my freezer is, by how many racks are on the wall, or by how much personal satisfaction you get from hunting or using the equipment that you own...I told you before I am an equipment nut,,,and even on my worst day, you would not be able to out-shoot me...I have been lucky in this business, I have shot with some of the best shots in the world(bows, rifles and "handguns",something you do not see alot ofin Canada) and have always been able to hold my own. This is not blowing my own horn, we already know how much better a "hunter" you are than I am, and how much older and senile you grow by the day(LOL, not hardly)

Wow! OK hi-tech freak that works,jaygail7.You target man and my good friend DNK great hunter! Me i am just lucky, the game comes to see and i select one or more. Plus on targets they jump in front of my arrows and i score well![8D][8D][8D]

Geeeze, my two Freedom Arms 454 and 44, 44 629, CZ 75, Erma 22 and 45 ACP comp gun must be my imagination! I shoot in my shop every day and once in a while when I'm settting up my bow after an equipment change I blow a shot. Why is it that Gold Tips litteraly explode and the Axis bounce off the concrete wall with no damage at all? I do own about three dozen Gold Tips so its not like I don't like them. I am not a great hunter just a good hunter. Everything else you yap about is not worth regurgetating so I just say that I prefer to call myself mature, LOL rather than older. Unlike a young punk like yourself, though widely self respected. Ya know maybe you are an older more senile fart than Mike and I. I bet you are typing away in an old age home, drooling at the mouth thinking you still shoot arrows!

HI-JACKING IN PROGRESS,,,,,,,Dnk, I know that all that "goobbly gook" and math and formulas are real confusing, have not heard lately of anyone going to Canada for institutions of higher learning( are there any) And tell us of your draconian laws pertaining to firearms(careful I looked them up,must demonstrate a need,collect,target shooters and registration) does your Gov. know of your bad, bad handguns? I bet you take a pretty pic on your gun registration card....It is a wonder you talk to us bad Americans, your Liberal Gov. would not like that if they heard(and they are listening)...Was it not a Liberal Puke that hi-jacked the spring bear season in Ontario, or has that been re-instated?????As far a concrete walls go, I would turn that wall to dust with my 50BMG(something you could not demonstrate a need to own)..Tell us how you hunt with a handgun, can you carry(I do) can you trade without telling your Gov.,can you do anything without telling them.Can you go to the bathroom without telling them? Your Liberal Gov. has a point, why spend all that money on defense when you have the only Superpower(AMERICA) to your south(and bad-mouthour Gov. at every turn we make,anybody heard about Iraq) I also heard that you Canadians do not like our National Anthem being played at hockey games( tell me that is not true dnk)....And by the way, THANK YOU, for supporting the NRA, an AMERICAN institution that will prevent the things that are happening to you from happening to me( you must understand we have A BILL OF RIGHTS that guarantees our GOD given rights)). Went by there a few weeks ago I wanted you to know it is a very nice building,and I did not see the brick with your name on it anywhere. Canadian imports, let me see, Excalibur(good thing) funny can not think of anything else.....All that Canadian whiskey must be going somewhere???(oh,that is your problem, you have the monoply, you have been drinking it all, never liked it anyway) Keep your eyes to the north Dnk, if you sight the HONG WONG DONG DUNG missle coming over the polar caps from N.Korea, do not let it bother you, your friendly SUPERPOWER to the south will shoot it down before it lands in your neck of the woods.............By the way guys I had to type at lightspeed(another thing dnk would not understand) the nurse is coming around with my meds and I was told if I was caught on the computor again today, my ration of DEPENDS(dnk knows about these) would be cut in half...... YOUR ADVERSARY(dnk look it up) Jay

Hey angry man, I guess you doubt my NRA member ship. Go and expend some excess energy and check out #080920388. You are going to blow a gasket or some thing else. Take a pill. I suspect that you only get one depends a day because of your condition. Yup the spring bear hunt was an embarassment because of the bowing down to lobbying but thats pretty well universal. Your panting and bantering about our/your politics is to say the least not lucid, I think you should stop watching so much black and white television. The remainder I cannot bother with even thinking about talking about on a hunting forum. I came here to talk about hunting, shooting, joke around and fire shots not talk about laws, nationality and other garbage.

RE: How to figure down range velocity and energy??
 
HI-JACKING STILL IN PROGRESS...... No anger here dnk, why would I doubt theNRA membership, you have my heart-felt thank you for supporting my GOD given rights thru an AMERICAN institution that will do nothing for your GOD given rights in your country...There are no NRA offices in Canada(I checked,am a member also) They also led me to look up your draconian gun rights, funny I did not hear you mention wether I was right or not...... I would be verrrrry careful to mention what firearms you own.....Tell me, you did not mention wether you like our National Anthem being played at hockey games in Canada, funny I did not hear the commotion when they played the Canadian Anthem in the UNITED STATES. YOUR ADVERSARY

Dnk 06-27-2006 03:54 PM

RE: How to figure down range velocity and energy??
 
Please enlighten me as to why you would be verrrry carefull to mention what firearms you own. As far as the other garbage goes, I don't care Mr. Adversary. Anger? Oh yeah there's anger some where maybe in your depends. LOL. Now what rights are you talking about? If you are talking about. If you are talking about the right to carry, there is good and bad with our laws. Some down right ignorant of firearms and some down right senselss. Canadians apparently are privilaged to own firearms. Right or wrong I do not care enough to change it so I do not lobby to change the laws. Yup our laws are too restricted and your's are too unrestricted in some ways. I like our safe storage laws but on the other hand I do like the fact that not everyone is allowed to carry a handgun. On the other hand if I lived in downtown Destroyit I would want to carry it. When I shot IPSC competetively in New York state my concealed carry permit allowed me to carry a handgun but I did not. I guess I did not feel the need. I would, however like to carry one of my handguns when I hunt but thats life but certainly not very important in the big picture. Sorry for not firing may shots at you.

Dang!! What a time to run out of pop-corn and Miller Lite!!! Htoler: I think they're bashing 10 pts. Do I have time to run to the store/bar??? Bar is 86 miles, but somehow I think I can get there and back before this one's over LOL

HI-JACKING STILL IN PROGRESS(stay tuned) Dnk,,,I really think you will be pushing up flowers(from underneath) before you convince anybody on an Americanhunting forum that the US gun control laws(all 38,000 of them) are not restrictive enough??????????????????????? Futhermore what the he!! is a Canadian "holding device"??????? What that means here is a fully loaded 44cal SS Charter Arms Bulldog loaded with MagSafes two fully loaded speedloaders and the gun in my right hand, now that is a holding device.....Gun ownership here is not and will not ever be a privilege as long as I draw a breath....Everyone, even you have a moral obligation(given to you by your GOD not byany two-bit government)to protect yourself and your loved ones, even if it takes deadly force... And futhermore I sure hope Dan got his beer and pretzels(or was it popcorn) and where in the he!! does he live that it is 80miles to the nearest bar. My, that is what you call the boonies.....................LOLYOUR ADVERSARY JAY

My friends i have come forth to ask you to return to the posts that was starting thread. We have all had fun and amusement and got to cut up abit. Continue the gun issues in proper forum or via private pm's, thank you. Invoking sites rules at this time. Lets get on to xbow issues and use of it in hunting. I repeat don't add anything to this threat other than orignal intent!

I live in a "dry" county in Arkansas. I can get Oklahoma beer [3.2%] 8.6 miles away, commonly referred to as rhymes w/ Hiss on the Move LOL. It's 86 miles to get real American beer, same distance as my nearest pro-shop. The UPS driver is my best friend, and I don't even know his name LOL. I drive at a higher velocity on the way there than the trip home, cause a 30 pack is "over the limit" on possession of alcohol. Welcome to Arkansas, set your watch back thirty years!!! Also the main reason for my facination w/ Excals, I can do it all right here. Popcorn is much closer.

RE: How to figure down range velocity and energy??
 
Planter, you asked about down range velocity and energy, correct?

I don;t know if this was answered in here somewhere, but initial energy is not the same and the only way to get the other would be to know how fast the bolt slows down as it travels. The easiest way would be to set up a chronograph at measured distances and get your velocity that way. Even bullets from firearms are and averageamount comparing ballistic coefficients for speed loss (deceleration) for a type of projectile. And that is affected by air density, wind, humidity, etc and I don;t know of any standard from anyone that will let you calculate that for a specific bolt, head, fletch, etc so to find your energy atX yards downrange you will need the chronograph.
The formula for Ek, kenetic energy is all you need for energy calculation once you have your wiegth and velocity at a set distance.

awshucks 06-28-2006 09:40 PM

RE: How to figure down range velocity and energy??
 
All true. I believe, but am not 100% sure that Excals site, possibly 10 pts and for sure the Italian site linked on another thread all have tables to determine this. IMHO, if you have a bunch to begin w/ it all comes out good down range. It seems most compounds need an arrow weight above 415 gr, and w/ fps in the 280-300 plus range, we would have enough k.e. out to at least 50 yds. Which is a little too far for white tail for me, but the k.e. is there.
