need y'alls help

[bigchast1]

I live in N.C.  and the club close to me has an all-around match. Rifle, shotgun, and pistola'.  My ? is will a 22-250 knock over pigs at 150, turkeys at 200, and  rams at 300 yds. I have two good accurate loads one with 50 grain, and one with 55 grain bullets.  3870 fps for the 50's, and unknown for the 55's. So can I use these or do I need a heavier bullet, it has a 1 in 14 twist rate.  I have access to other guns but, don't want to borrow if mine will work, if not I think I'll use the trusty 45-70 with 405 grainers and Pyrodex.

At that range unless the targets are hard steel you will punch through or do serious target damage with the 22-250. I don't know if the 80 grs MK used in the 223  twist will work. you may explore that option at 2700 FPS or so.
