.22-250 ai
Worker -
Howdy !
If you have both powders available, I'd suggest the RL-22.
Probably will render higher vel of the two.
Perhaps even better..... some AA3100 IF you got it.
My similar-sized .224" calibre wildcat would produce " bolt effort " upon openeing with a simple .1g r increase... once the charge was very clsoe to max ( with AA3100 ). That last full 1gr you want to try increasing in only .1gr increments.
A 6mm wildcat design I shoot was doing just fine while I was developing loads with RL-22 and Berger 88s. Towards the max, I went up .4gr instead of just .1gr; and the pressure " came on "' RIGHT NOW ! Backed off a simple
.1gr , pressure was fine; and stayed fine with subsequent load use.
( My gun, my widlcat, my loads ). Still for me... when RL-22 has had enough...it has had enough.
Back to the AA3100:
My .224" calibre wildcat put 3,500 on 75 "A"-Max. I switched from
FED LR Magnum Match to FED LR Match and groups shrank remarkably !
Load vel went to 3,420; but... it was worth it for the grouping capability.
I shot live grounghog, and some target shoots ( " groundhog & egg " ).
My point:
I suggest you wring-out the primers; IF you have various primers available to try.
Best of luck in your endeavors !
