Hey all, first post here. About 3 years ago I bought a box of factory winchester super x, .338 win mag, 300 grain power-point soft points. I am going for a brownie and a moose this year and would like to get an idea of what to expect with this round or if I should use something else. I have not been able find ballistics or bullet performance charts/info anywhere on the web or any other source as most tables stop at 250 gr. Anyone know why the 300 gr. has fell out of favor? Thanks.
p.s. A big thank you to all who post here. I have gained alot of knowledge from your willingness to share.
