So i want a new 300 win mag and can't decide. I have about 400 rnds of federal 180 gr soft points and 200 rnds of federal premium 180 gr barnes tsx factory ammo. I am considering a winchester XPR with 1 in 10 twist or a browning xbolt western hunter long range 1 in 8 twist both have 26" blued barrels. The winchester is $620.00 and browning $820.00 not concerned about price am more interested what twist for the ammo i have for elk hunting. Any input would be appreciated thanks in advance DAN.
