This round is known for its impressive velocity, excellent ..., 74grs. RL-26. 2800fps. 3.6” feeds good from AICS mag in the mdt chassis. 4 firings on brass and it still has tight primer pockets. Accuracy was good for a factory rifle consistently shot just over 1/2” at 100. Bullet seems to do its job on 2 bears, one at 992 yards and one at 530, and one bull elk at 840., 300 Win Mag is short for 300 Winchester Magnum. The 300 Win Mag takes a Magnum Large Rifle primer, though some have experimented with regular large rifle primers. Most all load data though recommends that you use a large rifle magnum primer, but experimentation may lead you to other preferences.
