what will happen when i hit a squirrel with my 70# bow with a fieldpoint backed with a washier .. will that destroy 90% of the meat due to trauma?

Not if you hit him in the head......  

you just love making my targets small ron haha looks like i should start practicing

Some them suckers seem so tough, it might just shake its head, pick that arra up and toss it back at ya!

if it throws a 600 grain arrow back at me after being hit by my 70# bow it deserves to live thats the chuck norris of squirrels

It'll be fine unless you slam the sucker in the rear legs!  It would probably tear them up fairly good.  Out of a 70 pound bow, if you want to minimize meat loss, I might be more inclined to try a steel blunt or a steel blunt covered with a rubber blunt.

Just fool'n with ya.....I do aim for the front part of a tree critter. I use judos, rubber blunts with wood and Hammers with my carbons. Best of luck to ya!

I meant to add in my earlier post, that you should be fine as long as you stay away from the hindquarters.

My preference though is a Ace Hex head or a Judo.

Caught one on the ground the other day. 43# BW 600grain arrow including 160 hex blunt, Took the top of his head completly off.  Jim Pyles

Too early to chase squirrels for me. Woods are still thick with foilage, hot, skeeters...and snakes are still out. I'll wait for Oct 1st when I can bowhunt those bigger rodents.

I use judo points and havn't ruined one yet, hitting them is hard enough most of time, they never stop moving!
