The 130 gr. load used 83.0 gr. of RL19. I don't have the exact velocity figures in front of me.
I will point out that my rifle is a Remington 700 LSS with a 'brake installed and has a very long freebore in it--reminiscent of the Weatherby MK V throat. It has had several hundred rounds through it using only Nosler brass. The loads are at or exceed book maximum by a small amount after considerable time at the loading and shooting bench.
I am forced to use the non-toxic stuff due to my being deep within the condor zone in California, but my experience with the Barnes has proven that it likes to be driven hard to deliver the best accuracy. Please don't use my data in your rifle without carefully working up to it.
The best I've ever been able to get out of the .300 wsm using the same bullet is just shy of 3,000 fps using Federal brass. I have not done much with Superformance powder in that cartridge, but the little I have done (with mediocre accuracy) put the velocity up to around 3,100 fps with that same bullet.
Wow, 3350fps with less than Max load. The max velocity for the 168gr is about 3200 with a Max of 79gr of R-22.
Two grains under with that much more speed? How far do you have that Chrony from the muzzle?
