Matt/PA-Steve Jackson.... KE for the PREDATOR.
 

Matt, and Steve, or anyone else that wants to help, If I am shooting the 27" technically 26.5" with a release, with the predator at 70# would it be a good Idea to go lighter to pick up some velocity, or stay at 453 grains with average speed and KE. Another question is, if I speed up the bow, will it afford me more KE because velocity is part of the KE equation? I want to be in the 60's somewhere for ft/lbs.
I am shooting, Steelforce cut from tip. If I hunt moose, I wanna be able to blow an arrow right through the ribcage. Thank's for any arrow, tip, fletch combinations you could give me, staying with in the 7-5gr per# mark.
I aslo like the forgivness of 5" feathers.
Good shooting.

55,
stodr, is correct......That estimate that I gave you of like 57# of KE is pretty much what you are stuck with unless you can lighten your string load a bit to pick up a few more feet per second with the same arrow weight.....
You can't up the draw weight,draw length,and lowering your arrow weight won't help.....so that's your only option.
If you're hunting Moose, don't go any lower in arrow weight(if anything go HEAVIER!).....that's a big critter and you're gonna need the KE AND the Momentum to get thru it.
Do yourself a favor and ask 5-Shot what "Cut to Tip" style head he recommends.......The "Steelforce" should be fine for whitetails, but his testing has shown athough super sharp out of the package, they are actually pretty fragile, and that the tip is very prone to curling upon impact with a hard surface.......Not sure how tough moose ribs are, but I'd want the TOUGHEST head I could find if I was hunting them myself.

Sorry I can't really change that KE too much if you leave the bow as is, but if you get rid of a peep w/ tubing and any extra nock-sets, and either use no silencers or very light ones like "String Leeches"......you can pick up maybe as much as 10fps with the same arrow weight, and that might be enough to get you to that 60+ft/lb of KE mark, but now that you mentioned the 26.5" draw......don't count on it bud.
Trust me you can still kill a moose at 55ft lbs of KE or so.....get a STRONG broadhead, razor sharp, and a heavy arrow, and put it where it counts......and it will do just fine.

55, I used to play with different bow/arrow combos to try and tweak more ke out of them. The answers that were already posted are right on the money. A bow only has what it has. In my rather crude testing, I did find a pattern. Without changing anything on the bow, a heavier/slower arrow always developed more ke in my tests. But I am talking about #`s like 68ke vs. maybe 69.5-70ke. Not enough to sway your preference on arrow weight. I saw your earlier post about your new champion, 75ke with 27" draw. I did not want to burst your bubble, so I did not respond. If there are any bows out there that could develop over 65ke, at 27" draw, I don`t know about them. Heck, I only develop 66.75ke with a 29" draw. I have had bows that would get me into the low 70ke range at that draw length, but I don`t care if my arrow buries 2" into the dirt, or 6" into the dirt, after passing through the deer I shoot. 57-60 ke will do anything you need done, though I would follow Matt/PA`s advice, on really big game go with a heavier arrow/broadhead combo.

55, i shot a moose this year and my arrow blew right through double lung at 60 yds, i use gold tips with a 140gr. bear razorhead. but im pushing 77lbs of ke. {285fps 425gr arrows} the only thing he did was flinch and went down 50 yds later {he was chasing some cows but never did catch up}. my new bow is pushing 100lbs of KE with the same arrows. the bear razorhead is very well made but again its my opinion. i have the arrow hanging on my wall the head is still perfect. you would have to spend some time sharpining these but i dont mind gives me something to do on these long winter nights.
anyways you might want to look at these they have been around 50 some years for a reason and havent changed much.

again this is just my factual opinion

RE: Matt/PA-Steve Jackson.... KE for the PREDATOR.
 

I think the first cut's would do the job well. They are very tough. As for the moose thing, I just wanted some idea's on what you would need. I have heard of 40# bow's doing the job on a moose. You just need to know where to shoot them. If I get a good 50Ft/lbs of energy I will be happy. Thanks for the reply's.

In Ak's example above, when the arrow "blew through" the moose, it was under 60# KE, by the time it got there @ 60 yards.

With good shot placement, you will have more than enough KE and Momentum.

What they said.

RE: Matt/PA-Steve Jackson.... KE for the PREDATOR.
 

thanks rob, i guess i dident make that part of the point clear {after re reading my post} but you are corect at 60 yds an arrow looses a lot of its energy, just dont tell that to the moose or the tree i had to pry my arrow out of. gotta love the first cut heads.
