6.5CM Better Velocites with CCI 450 Small Rifle Primer & IMR4451
Still a work in progress…
Those who have been following my Load Development in my Savage Engage 110 Desert Tactical chambered in 6.5 Creedmoor have seen my previous velocities barely peeking over 2630 FPS with Remington 7 1/2 SRP behind IMR 4451. I’m using fire-formed Starline SRP brass as the control subject here, and changed the primers to CCI 450 magnum primers. To my surprise, I achieved a good velocity jump. Optical Chrono’s have been known to lie, so later, once this load development is completed, I’ll test it out at long-range and compare calculated ballistic drop to actual dope.
Any suggestions and feedback are greatly appreciated. The groups today showed some weird stringing/flyers with a couple of promising nodes.
