Hi everyone, I have been shooting my new toy seriously for about a week now and have a question about my penetration. My bow is 45lb@28", I draw 28.5". I'm shooting 35-55 goldtip xt hunters that are 30.5" from tip of insert to tip of nock, I have 100gr brass inserts installed and shoot 150gr heads which brings my total arrow weight to around 500gr. I've been shooting my new block target at 15 yards and getting 7inches of penetration with a practice tip. I'm shooting off the shelf and still getting some up and down movement of my arrows which I think that I need to adjust my nock on the string to correct. My question is: Is that decent penetration? I will soon be shooting 150 razorcaps for practice and hunting. Any suggestions?
