Well, just got back from my 2nd elk trip this year. My 338 win mag was acting up so I left it home....sending the scope in to have it checked. I was a little nervous, but I decided to take my new Gunwerks 6.5x284. 140 grain Bergers and trophy sized elk didn't seem like a great match to me. Boy was I wrong! 1st bull was taken across a large canyon at 752 yards. 1 shot and he piled up within 10 yards! Actually got an exit on the off shoulder....amazing. 2nd bull was a bit closer...435 yards. Bull took a lung shot and made it about 20 yards before falling over. No exit, but like the other bull, bled out very quickly inside the chest cavity. Both hunts took place out of state for me and both were guided. The guides and the spotters were amazed at the effects that these "little bullets" had on these big bulls. "Holy crap! I've never seen anything like that! Did you see how fast he went down?". This and similar comments ruled both days. 2 shots and 2 dead bulls....within a combined 30 yds from where they were shot. Made a believer out of me!!
