Tried to load those 300 FPB in my rifle the other day, the bullet is too big to even start in the bore. Luckily, Hornady was nice enough to swap me for some 300 gr SSTs .45/.50 sabots, which have always shot well out of this rifle. As soon as I get those, I'll start doing load development w/my new can of Blackhorn 209 and CCI 209M primers. Was trying to get away from sabots, but they still seem to work the best for this tight-bored little rifle, which isn't the end of the world either. (SO ANYONE WHO OWNS THE PREVIOUS GENERATION CVA WOLF BEWARE, THIS BULLET IS TOO BIG).
