Gun Info Pre 64 Model 70 with 27" Brux Barrel
Comment That velocity is not a typo. The most efficient powder/barrel/cartridge combination I have encountered. Since there were no published data I worked up to this load very carefully. No signs of pressure in my rifle, but yours might be different. Compressed load. Maybe RL 26 is all it is cracked up to be?
