I assume the .57 momentum recommendation is measured at launch, meaning the effective momentum required is actually lower based on how far away the animal is from you.

However, if you wanted to make sure and have .57 all the way out to 35 yards, you can do it with a 500 grain arrow flying at 275 fps. This gives you:

0 yards- .609
10 yards- .597
20 yards- .586
30 yards- .575
35 yards- .57

Looks to be a perfect compromise between flat shooting and high ke and momentum. A good goal to shoot for, no?

No wonder you long arm guys have all the fun Easy to do with most modern 70# compounds drawing 30" and above, a little harder at 29" and a difficult proposition at 28" , unless I' m missing something...

When I get a smooth drawing, cool looking, easy shooting quiet bow that hits this mark at a 28" draw at 70#s, I' m done looking at new bows, until they can do it at 60#s

How far off do you think this is, realistically?
