I was getting down to the last bit of RL22 I had from my original 4 lb keg (not enough for practice and hunting season anyway), so I broke into the new RL22. Now I dropped the charge down almost 10%, my other load was 66 grains I dropped to 60 grains to start with.
60 and 61 both seemed fine, both shot very well mind you and then at 62 grains it felt like a normal 66 grain charge (this also shot very well, under 3/4 of inch). I then shot two of the 3 at 64 grains and looked at the brass and saw very flat primers and a bright shiny mark from the extractor. Did not shoot the third round. I stupidly did not bring the chrono to see where I was there. But I found it interesting I only got to 62 grains with the same powder but different lot number. Can lot numbers very that much?
I'm going back out with the more at 62 grains and will take the chrono. I'm pulling the ones at 65 and 66 grains though. A month ago I learned the hard way with different lot number of brass why you should drop 10% and work up. I loaded my standard load into a Win case which is what I use and promptly blew the primers out of three cases. I also had to replace the extractor as it was stuck in the bolt (stupid, stupid, stupid) Thank fully that was al it was.
