Chap & Others -> Ballistic Charts
 

Here are three charts using the bullet information I have compliled. They are all shown with a 6" point blank range - same temp - same altitude - tried to keep everthing equal comparing the 45/250SW 45/300Speer Gold Dot and the 45/300 SpeerUCSP.

This program also actually lets me shoot the bullet at a target - I select the POA and hit enter and it shows POI. I can also add in the wind factor and up and down angles.... it is fun to play with once in awhile - can do it virtually for any bullet if I have the information to plug in...

Well anyway here you go...

RE: Chap & Others -> Ballistic Charts
 

Yes, and this program can do it for any bullet from any gun with any charge? Very cool. I can tell from the trajectory of the Speer 300g Unicore, that they drop off the wall after 150, the GD do a lot better and the SW are great. My conclusion is out to 160 all bullets are shooting thru 4" pipe, wheras the Unicore was only good as a plinking bullet out to 130.So for practice on 150 yard targets go with theGD for the SW,right?Barnes makes the program, how much does it cost?
Thanks Chap

SabotLoader,

Is that the ballistics program from the Barnes Gold club? I was checking that out a few weeks ago, looks pretty cool. Are you doing the trial or did you get the program? I was wondering if the fee is good forever or do you need to renew it each year?

I think it was about $50 can not remember for sure you can go to Barnes Bullets and down load it - gives you few free trys then you have to purchase it....

Justto add more to the mess look @ this chart for a 200 XTP - not a Shockwave a XTP....

Check the velocity and the energy with a 110 grains of T7-2f

Then imagine a 200 grain SW with 150 grain pellet charge out of the barrel @ 2400 fps....

RE: Chap & Others -> Ballistic Charts
 

I see the energy on this 200G is only 200ft lbs less than the 300g Gold Dot. That is impressive. But why would they not shed their jackets like the 260 and 300g XTP? I am sure the 200g SW with 150g of Pyrodex is going to have a lot of energy downrange, not much bullet drop on the SW either. I tried them in my Knight and Omega, they are the most difficult loading bullet out there in my guns. I didn't try them yet with a split rib, I am not planning on taking any 200 yard shot with my muzzie, so the Nosler will continue to be my bullet of choice until I use them up. Then I will use the XTPs and the Gold Dots. The shoot well in a TC FL with 100g of loose goex, so I am sure they will go nice in an in-line.
thanks I will download the pgm and see how it works.
Is it $50 one time or every year a renewal fee for new guns that have come out?

RE: Chap & Others -> Ballistic Charts
 

Sabot loader it would suprise a few people to know just what velocity a 150gr RSgr with a 50/40 200gr SW gets I hate to put what I get out of my Omega because my Chrony is one of the very early ones and I don't trust it 100% but is any one else getting over 2450 fps? And how would this compare to a 250 grSW at 2150? Lee

RE: Chap & Others -> Ballistic Charts
 

Lee, I think that'd be pretty close for the 200 SW. The 250 SW though, should have more muzzle energy than 200 with the same charge. It must be something about the sabot/bullet resistance in the bore (not just the inertial effects of the bullet weights). Because of the higher muzzle energy, the most efficient is probably the 200. Do youknow off-hand which has the higher B.C. ? I'd test in the Apex but that load is prohibited in the Apex.

RE: Chap & Others -> Ballistic Charts
 

Pglasgow, I looked them up at one time and I really dont remember but they were fairly close.
My problem is that I can get one hole groups with 150 and the 50/40 200gr but I have to drop the powder load to 130 for the 250's to shoot. I used the 200gr deer hunting this year and was impressed. Lee

It is from Barnes Bullets..

I bought the program.

It has been a one time so far for me - think I have downloaded 2 or 3 upgrades - have not checked lately...

mike

RE: Chap & Others -> Ballistic Charts
 

Since the 200-150 has way more muzzle energy than the 250-130 and the B.C.s are really close, its energy throughout its flight should dwarf the 250. The 200 beats it hands down. I notice this is a +- 2" elevation load out to 200 yards. Like a Savage.Very impressive and accurate to boot.

Added: Hey Lee, it occurs to me that the 250's developenough pressure and heat with 150 grains that the sabots break down spilling breech gas. Have you recovered spent sabots to compare them? It might explain why the 250has lower muzzle energy than the 200's and why the don't print tightly like the 200's with that charge.

I did download it from Barnes Bullets....

I bought the program....

It has been a one fee for me so far.. - I have had it for several years and have downloaded 2 or 3 upgrades...

RE: Chap & Others -> Ballistic Charts
 

I am not sure of the exact trajectory but I can center the 18 inch gong by aiming just below the top edge of it on a windless day @ 240 yds which I though was pretty decant for a muzzle loader. The buck I busted with it a while back never took a single step of course he was only 30yds away. Lee

RE: Chap & Others -> Ballistic Charts
 

lemoyne

I have not shot this load myself because I do notshoot sockwaves only the XTP version, but I know of two other people that are reporting 2400+ per sec with the load you are talking about....

I do not have a chart worked up fora 250 @ 2150.. would you want one put up?

RE: Chap & Others -> Ballistic Charts
 

Lee, I would be interested in how 150 grains of pellets chronys with the 200 SW as opposed to 150 grains RS. Do you know?

RE: Chap & Others -> Ballistic Charts
 

sabotloader, Actually I am more interested in the 200gr at 2480 which is about an average with my old Chrony I was so impressed at the job they did on that deer this year that I am thinking I will proably use either the 200gr XTP or the 200gr SW for Boar and Bear as well as deer. I was just looking at yor charts and trying to figure what a comparison would be like. That 200 XTP is wicked out to 150 yds. Lee

RE: Chap & Others -> Ballistic Charts
 

lemoyne

200 grain SW @ 2480 is what you want correct... or 200 XTP @ 2480?

RE: Chap & Others -> Ballistic Charts
 

Pglasgow, Well like I said my Chrony is very old, but to answer your question the average show up as 70 to 80 fps faster and I really don't understand why that should be but the high low is narrower to so?? maybe I need a new Chrony. Lee

RE: Chap & Others -> Ballistic Charts
 

sabotloader, I use and intend to keep using both but the one I will load when I know it might be a big animal or long range will be the SW. And Thanksfor all the neat things you do for us and the help. Lee

RE: Chap & Others -> Ballistic Charts
 

Forgive me, but should I take it to mean that the RS is faster than pellets by 70 to 80 fps?

You know I thought something was wrong with my chrony when I first got it. I had wide variations in velocities also with RS and P. On some loads as much as 100 fps. But with 3fblackpowder they generally settle in with only +-10 fps. Its very amazing and itjust tells me that the subs are going to vary a little in velocity. Even so, at 2400 fps, the effects are not very noticeable as evidenced by the one hole groups you described.

RE: Chap & Others -> Ballistic Charts
 

PglasgowSorry I should have been more accurate, the losse averages 2483 +- 65 fps the pellets average 2546 +- 48 fps. Lee

RE: Chap & Others -> Ballistic Charts
 

Oh my!!! Wow. I wouldn't have suspected that. That's almost 2900 ft-lbs at the muzzle.

The three pellet load is allowed in the Apex is why I was curious. I may try some chronys myself and let you know what my chrony reads. Thanks for the info.
