Mr. Wick...Nice shooting! Keep doing what you're doing...because it's working. Not because you read it on the internet, but because you TESTED it for yourself and the results don't lie. They might not be statistically significant to some people but that's all the more reason to just keep doing it until it doesn't work as well as something else...for YOU.
When someone says.."that'll never work", that's motivation to find out if they're right or just parroting what they've read or heard somewhere. Most of my BR "career" has been made up of testing and doing "what will never work." FWIW, I've gone as much as 50 firings on Lapua brass without annealing and that's stepping on the gas hard with it the whole time. The primer pockets were terrible when the necks finally gave out and accuracy suffered. But I'm just a short range shooter, too.
Nevertheless, I respect anyone who does their own testing and walks in their own footprints alone, successfully. This game is chock full of examples of things that "have to be done to win", and even when you prove them wrong, well, it was a fluke or it was the shooter or whatever. You get my point. Kudos to you for actually doing it rather than falling in line like a good foot soldier.
