[QUOTE="Lefty7mmstw, post: 687067, member: 48043"] I am not 100% sure what cal it would be, the 243 wssm holds merit also, as does the 243 and 25-06 if I go encore. I've been able to get 2800 fps with the striker with 100 grain in a 243(14"), so it shouldn't be tough to do a beat that with a bit more capacity. I've got a 44 for big bore engagement to 200 yards and over that I'll use a rifle so smaller cals are what I'm looking at for the most part. We've noticed a rather marked improvement with pistol performance over the years by going with slightly faster powders than usual and lighting them hot, ie. a 215 in a 243. I could beat standard velocity by nearly 200 fps with v540 and not run higher than normal pressure. In a 24" barreled rifle the loads were about normal speed wise. With the enhanced pressure curve of superformance and a few of the other newer powders I could see where they would be trouble with a sub 20" barrel. With a 300 wsm pistol I'd look at rl17; it would be a hoot with 165's. I think my father is still using i4350 in his wsm pistol. You are correct about the expansion ratio mattering in a pistol, but not as much as Herret and some of the others thought. I'm loosing around 400 fps with my 22-250 with a 14" barrel. It'll still do 3500 fps with 45 grain factory win's and do 5 in an inch at 100yards with it. I haven't worked with it with handloads enough to care on speed as my first couple loads shot well; load development complete. [/QUOTE]
