  I don`t have any idea what the load were, but you should be able to get 2,700 to 2,800 fps. from your barrel with a 55 gr. bullet and with full metal jackets they should go through a 3/4 ply wood. With a 55 gr. bullet you should get a max. point blant range of around 210 yrds. with your barrel and 55 grn. bullets loaded at 2,750 to 2,800 fps.

after i wrote this i called my buddy he said that after i left he checked the wood there was no more bullet heads in it just that one he also said that there was a chance that the bullet hit the ground in front of the target we just put the scope on and were trying to get it sighted in so it is possible that the bullet hit the ground first this could be the only thing we could think of so i will try again and post the results i kinda feel stupid but that happens sometimes in life
