What kind of FPS did you get on the 85, 100 & 120 grain bullets?
What powders are getting the best accuracy?
Hello, I hope I can help you so that in the long term you stand to benefit from this advice. The .264 is the short magnum brass necked all the way down to 6.5. As such, if you are a gunsmith you may have some advantage when using this caliber because if you want prime accuracy, the only way you can make long range hits, you will be rebarrelling this cailber rifle every year. The bullets that the 6.5 utilizes for long range are the excellent 140 grain projectiles; anything less you are cheating yourself because the HIGH B.C. of the 140 grain 6.5 bullets are THE reason they dominate 1,000 yard rifle competition. if you want to shoot lighter grain 6.5 bullets for shorter range purposes, please do yourself a favor and shoot a much smaller cartridge that is capable of finite accuracy such as the .260 Remington and the excellent 6.5 x 284.
All the velocity advantage you may gain with the .264 Magnum case comes at the expense of throat erosion. Ten years ago I did some experimental work that involved necking down the .378 Weatherby cartridge to .22 caliber which had been done many years ago. Velocities reached 5,016 fps and we also recorded over 5 inches of throat erosion in just less than 80 rounds!
Velocity is fine, but at the cost of accuracy you gain nothing! If you really like to shot at longer ranges try the 6.5 x 284. There are very good practical reasons why it is so popular, plainly put, its better! When you take the short magnum case and neck it up just twenty thousandth to 7mm the throats ( the key to retaining both high velocity and finite accuracy) last a lot longer. This is also why the 7mm magnum is so much mor popular than the .264
I have used the 6.5 for hunting since the mid 1960's and wish I had a 6.5 x 284 all this time because I really believe its simply better than any of the others now that there is target quality brass and better bullets available.
Good luck and accurate shooting to you,
