Time to get serious about load development for my new 22BR. Krieger HV 8" twist on a Panda action. Main use is ground squirrels out to 400ish yards, then maybe some priarie dogs further out and an occasional F-class match if I ever get time. I've got some 50gr vmax, 55gr vmax, 69gr lapua, and 75gr Amax all moly coated if that matters. What are you goto powders/loads in each of those weights. I've got a pretty good selection of powders on hand, mainly Hogden but a couple others. No VV so don't bother. Not looking for blistering speed but that is a plus if it will shoot. Trying to avoid trying powders out of the optimum burn rate for each weight. Going to take either the 50 or 55 for squirrels, whichever shoots better, with a few heavies for the occasional long shot that may be provided.
