[QUOTE="Varminator 911, post: 246841, member: 9705"] I've got a 300 Jarrett, must be about the same as your 30 Hart. I think 3300 would require a lot of psi, too much for me. In other words, I don't think it would be worth the trouble and expense. What I'm thinking about is not more velocity but more bullet. There are some new bullets, as yet unproven, that may have a bc near 0.9, maybe even more. That will get you a lot further than an extra couple hundred fps. Compare a 220 gn with 0.9 bc at 3000 fps to the 210 Berger at 3150 or even 3400 and see how they compare. I'll take the high bc any day. Of course the 210 Berger is here, the 220 HAT is not. 911 [/QUOTE]
