Hmmm, I haven't given broadhead choice much thought until now. I was just going to go with the usual 2 inch Hammerheads but with that much KE I might look for something bigger.

Do they make something bigger?

:eek:;)

Pat told me they don't AMO their bows, but he did fling some different weighted arrows through the chrony and gave me the results. Doing some quick extrapolating from his tests to my desired set up, ponder this-

A 70# allegiance drawn 29" should fling a 550 grain arrow approximately 275 fps, for a whalloping 92 foot #s of KE, and momentum out the ying yang.

This just doesn't seem possible to me for some reason. If you get 275 with that arrow weight I would suscept that the 29 inch draw length is not really 29 inches AMO. I would have to see it and measure it myself to believe it..

good luck at any rate. I'll bet it would be quiet though.

Bees, we're both right :)

I corrected myself a few posts back. I had mistakenly figured based on a 30" draw. 29" draw does 265ish with just under 86#s of KE... ;)

Oh I suppose I should read all the posts before I replay. But that is still fast for that arrow weight. I imagine you are drawing 70lbs or what ever max is for a long time. to aggressive for me, shoulders wouldn't take it, what is the brace height on that thing?

I believe 7", with the bulk of the peak draw in the front 1/3 of the draw cycle, when most seem to be the strongest since using their larger muscle groups.

Ok, I just realized I figured for a 30" draw, not 29". At 29" it should do 265ish, for just under 86#s of KE... Probably still more than adequate.
I still don't see that happening at 60 lbs pull. At 70 lbs and 30 inch draw if you had a bow that would shoot at the top end of the listed specs (328) and you use the 3.4 number that Matt provided that would still put you at a loss of 59 fps for a top speed of 269 fps with a 70 lb bow. That is IF it is at the top end of the specs and IF the 3.4 number holds up. So I just don't see a 60 lb bow pulling that off. Not trying to rain on anyones parade I just don't want people to be disappointed when the bows get here and they don't live up to expectations that may have been set a little to high.

PS with my numbers it comes out to 88 lbs of KE with a 70 lb bow which is still pretty awesome.

MAT/PA ,Buckblasters should do the trick for you , 6 blades and I think over 3" cut , Should feild dress them at the point of impact :)

Me either. That's why I said 70# in my first post... :)

Ahh...I got off on the wrong track thinking you were talking about a 60 lb bow. But the inch less draw puts in in the same boat basically IMO. I still don't think it's going to make it into the 260's with the average Allegiance. An exceptional one may barely crack the 260 mark at the specs you listed but it will be the exception and not the rule.

You're quite possibly right, but remember this is with the nock and hush kit. Some tweaking could be done if one desired. Either way, it seems to be packing a whallop with heavier arrows, while still providing blistering speeds with lighter arrows, not a combo I'm used to seeing.

Time will tell, until then, we'll continue pondering... :)
