Ladder and/or OCW Assistance
Have 3 rifles to tune. The third one will be short barrel life firearm thus want to learn on the other two minimize rounds through the third.
Figured I'd do a Ladder test on the 243 to get narrow the options. Then OCW to get a load that would be consistent with all of the variables that naturally occur (SD, ES, Temperature, etc)
First attempt was a miserable failure. Chose wrong powder as the "books" were way off on max load. Thus found nodes that were way down in "expected" velocity.
Switched powder from RL-22 to H-4831. Fired several through the chrono to get an idea of velocity/pressure. With this information how would I go about selecting 3 or 4 loads for an OCW without doing a 10 or 20 shot ladder test?
Going to have good weather for the next couple of days and want to get with the program. Any assistance would be appreciated.
I may be the slowest guy on the mountain . . . . but . . . . I'm on the mountain!
