[QUOTE="daveosok, post: 74047"] I would go with a 1:10 twist, 300 RUM. You should be able to launch the 180 grainers at 3250 or better. I know for a fact that 100 grains of H50BMG will net you 3100 fps. Step up to Retumbo or H1000 and you can easily hit 3300 plus. In a rifle with a 34 in barrel we were able to get a 190 going 3600 fps behinid 100 grains of H1000. I would cautiously work up to this speed as with 100 grains of anything your looking at a butt load of powder to be ignited. Speed however does not always mean accuracy. We got lucky and the 3600 fps netted us some impressive groups at 500 yards so we never bothered to check anything else. But generally speaking VLD style bullets or SMK like to be pushed as fast as they can but will perform great at slower velocities too. All this does is beat the wind and drop better when going faster, also burns out barrels the faster you go but whos counting. If your just getting into this it is a money pit the likes of which your wife/girlfriend will never understand, never try and explain it either, just mention shoes and how many pairs are needed as we only have two feet you should be able to avoid arguments. Reason I suggested 1:10 is it wont limit you if you choose to go to heavier bullets with higher b.c. if you stick with the 1:12 you may encounter stability issues with heavier bullets. I dont know as all my rifles are fast twist and shoot heavy bullets, maybe the other fellas on here can pipe in. [/QUOTE]
