Has anyone done much with the heavier bullets with this cartridge for use in rifles? I am interested in putting together a rifle,or two or three, if I get hooked) for 300-meter prone and three position shooting. I have a Shilen DGA BP-S to get started with, and the inclination to assemble it into something exciting.
The reason I am interested in the heavier bullets is that my experience in Highpower leads me to believe they are a better starting point. With similar momentum,bullet weight * speed) at the muzzle, the heavier bullets require less dope per change in conditions. Assuming everyone makes mistakes, and that the guy shooting next to me makes about the same number of mistakes I do, heavier bullets should help me out in a pinch. When I shot against guys shooting 80-grain VLDs with charge weights pumped up as high as they could go, I used 175-grain MatchKings with moderate loads and did very very well.
The few articles I found suggest that most BR cartridge shooters like the moderate weight 6mm bullets best. Does the 6.5mm BR give up too much to the 6mm? Do these cartridges lose much precision when the bullets are not driven to the higher speeds? What about a 6.5mm BRX? Would it make up enough of the difference to push 120-grain bullets as fast as a 6mm BR can move a 107?
I can happily forfeit some loss in precision to gain some forgiveness in windage errors. After all, an inner 9 from a super-tight shooting rifle isn't nearly as good as an outer 10 from a pretty-good shooting rifle.
Thanks in advance for your comments/suggestions.
