Re: 6.5-284 Load Data
My six-five is a 30 1/2" 5 groove Pac-Nor barrel. I shoot 140 grain Berger Vld's at 3115 avg with 50.0 grains of RL-22. It shoots about 3/8" at 100 yards, 2" at 600, and it has shot a 7 shot 22" group at 1 mile. It is a fairly hot load (still easy on my Norma brass) and I run about .001" clearance on each side of the neck. The standard deviation with several lots of RL-22 has always been hovering around 4 to 9 fps.
On a brand new barrel, I would suggest using the Bergers or the A-max for long range hunting as they are much more frangible than the Sierras and are more likely to open up. At some point in the barrel's life though, you will probably have to switch to the sierra's because they tolerate rough throats better than J4 jacketed bullets.
I shot a doe antelope in Wild-oming last fall at 1030 yards with the Bergers and I thought they did a really good job. Total penetration yet they still caused much damage. Shrapnel was quite extensive.
If it's not far, it's boring.
