Old rifle, new barrel and caliber

[Hi Ball]

338Mag.......You might want to give those Hornady 160 grainers a try in your new barrel! I had friends years ago who swore by those bullets on moose and the penetration they gave when shot
around the 2600fps velocity mark. Now at 2750fps those bullets would start to fragment or slip a jacket I was told.

I tried to purchase a new model 70 Winchester .264 magnum sometime back, only Winchester does not chamber the caliber anymore.......I'ts a real shame too! Looks like you got your .264 mag shooting very well now.....Good Luck with your new toy!
