[QUOTE="RT2506, post: 1788841, member: 10178"] You need to understand the Weatherby chambering. The reason it has that long free bore is to reduce pressure. Remember 70+ years ago when the 300WM was designed there were not any powders slower than around the 4350s and H4831 which was a surplus military powder. With these you can get more velocity with safe pressure at the standard factory ammo COAL with the long free bore. Jump forward 70ish years and there are all these new sloooooow powders and fancy sleek long heavy bullets and the thoughts that you need to have the bullet close to the lands to shoot it's best but want screaming velocity and you now have your primer popping condition. You need to know the limitations of the round and work within it's limits. If you can't live with the limitations of the 300 WM then you will need a larger capacity case. [/QUOTE]
