    Because of the high velocity of the cartridge, you will do well with premium bullets if hunting large game, especially at closer ranges. Some good choices are Barnes TTSX, Swift A-Frame, Trophy Bonded and Nosler Partition. Personally, I always load Barnes TSX and TTSX in all my big game rifles. I've gotten outstanding performance with them. IMO they are worth the extra cost above conventional bullets.

    copper vs lead jacketed hunting bullets

    I live around a half dozen OUTFITTERS and they all claim that if you cant sign your hunting tag with your bullet dont us it. the horror stories they tell well make you a believer. I've read countless post here that swear by there copper bullets or there ballistic tip bullets. I shoot a lot Nossler ballistic tips in my
    22-250 and love them. never loaded any Barns bullets, In my mag. riffles i shoot Speer Grand Slam

    the first barnes triple shock going left to right is out of my bear i shot in the front shoulders at 350 yards the second is out of a cow elk i shot at 300 yards and the third is out of a mule deer that jumped up about 50 yards in front of me. all the bullets were right on the opposite side just inside the skin and everything between a entrance and the bullet was blown into a million pieces. the triple shock unloads all its power inside the animal.

    I have recovered two 300 grain .375 TSX's from 2 moose that I shot, and they look identical to the one you have pictured. The same for two 53 grainers using a .223 on deer. There have been many other kills on deer and black bear using .308 and .375 H&H, with outstanding results (complete pass throughs with no bullets recovered). I really can't say enough good stuff about Barnes TSX bullets.

    but what about 450 to 600 yards out do you think they will still expand enough i shoot 250 grain grand slams out of 338 win

    I also use Barnes in .223 (53gr), 7mm Rem Mag (140 & 160gr), 8x57 (160 and 180 gr). Stellar bullets. I bought a bunch of .223 and 7mm when they changed the name to TSX. The flat base was XFB before. I picked up many boxes from their site for $14.00/17.00. Still have 250 for .223 and 400 for 7mm.

    o ya!! they do excellent with long range! i got a 6x6 bull 3 years ago between 550 and 650 yards shooting a 225 grain barnes triple shoc. i missed the first shot then planted the second right through his lungs which dropped him and then when i started walking up on him he jumped up and i put one in his front shoulders when i was about 250 yards from him and he was done after that they just tip right over.

    how do you like the 250 grainers?

    i wasnt holding very good groups through mine with them so i dropped down to 225 grainers and boy do those shot nice!! but ever gun shots different so 250 grain bullets may be the ticket for your gun. :)

    It's a Sako AV. Originally it wouldn't shoot worth a darn. I had the barrel replaced with a Shilen. Big improvement.

    oh very nice! i love mine!!:) its an incredible caliber, it is surprisingly flat shooting for how large a bullet its pushes! Mine is a Ruger no.1 375 H&H mag and ive hit elk at 550 yards and just barely raising over its back! when that 300 grain bullet hits that elk that thing hits the ground harder then that bullet hits it!

    what grain of bullet do you use through yours?

    So far I've only used the 300 gr. Shot 2 moose, 1 at about 75 yards and the other at about 125 yards. Both dropped in their tracks.

    I don't have any personal experience at such long ranges, but the plastic tip on the TTSX's are supposed to ensure expansion even at long ranges, where the velocity has dropped off. In my opinion, they would be worth a try.
