.284/ .284 improved or 7mm RSAUM shooting Berger 180gr. Hybrids or similar.
To get better ballistics from a .30 caliber, you need to be shooting a 215 gr. hybrid, 220 gr SMK, etc. Then, you'll still need a case with enough capacity to drive the bullet fast enough to beat the 7's.
Unbiased Barnard, BAT, Kelbly, Nesika Bay x2, Remington x3, Browning, Marsh, Ruger x2, Savage x3, UltraLight Arms, AR15 x3 owner. I like 'em all.
