Re: 300 Weatherby and 240 SMKs could this be correct?
You should not have a problem achieving 2850 and in fact I bet your numbers are spot on. I use exactly 70.0gr of RL-22 out of my 300WBY heavy gun (30 inch krieger) with the 240ís and I am shooting at exactly 2790fps. Thus with the additional 2.3 gr of powder, you could certainly be shooting the pills 60fps faster then I am shooting them out of my barrel.
By the way, I truly believe this is one of the best bullet-cartage combinations. Not only does my gun regularly shoot in the .2ís at 100 yds if I do my part, but itís also an amazingly accurate 1000 yd varmint gunÖ
