Ok, so I’ve gone from concentrating on archery and grabbing a rifle and a box of random ammo when archery season is over, to trying to get more serious about my rifle shooting. I’m doing load development for a 6.5 creedmoor in a savage long range 110.
Berger 140 vld hunters
H4350
Remington 7 1/2 BR primers
Lapua SRP
I know there are a 100 ways to skin a cat so I’m hoping to hear if this is a reasonable way of doing the load development, or if I’m skipping/overlooking a step?
1. Ladder test to find max velocity and possibly velocity node through a chrono
For a starting point, go .020” off the lands and run from 36.0 to 42.5 in .5 grain increments until I see pressure signs or find a velocity node.
2. Using the preferred powder load in step 1, load 3-4 bullets at different cbto, starting at .010”, .020, .030, .040, .050 from the lands and see if I can find the most accurate cbto.
Anything I’m missing/overlooking/doing out of order?
