Re: 6.5 STW loads
I can get 3400 fps out of my 28" barrel with the 140 using several different powders. H-870 is the best with single digit spreads. Retumbo also does well. The load I use most is a 130 scirroco at just under 3550 fps. This bullet is tough and will hold together at high speed when it hits an animal. BC is mid .5's. I have made some long fun shots on antelope and deer with it. It is fun to shoot. Just take care of the barrel and do not over heat it and you will be fine. It is one of the best long range rifles made. Check the ballistics of a .612 bc going over 3400 fps and you see what I mean. It is a very good rifle and very accurate.
Predictions are difficult, especially when they involve the future
