I took my Marlin 795 out yesterday to try it at 450 yards. Yes i know its nutty and all. I was using Federal Champion bulk ammo. I was able to get some hits on it but nothing reliable I found one of the bullets that hit the very edge of the target and tore in half and it looks like (by the scrape marks on the bullet) the bullet hit sideways. I wondered if this could be the problem and the recovered round seems to verify it. I think the ULTRA long distance for that round is destabilizing it. Its one of those times that you go out shooting and come back not feeling the best about your time spent out there. Oh well....ya win some ya loose some.
