Right now I worked up to 36.5 gr of varget shooting the 1365 sierra sbt. Groups are getting better and no signs of high pressure. If I decided to try different primers or cases.( remington cases and cci primers right now I use) Should I lower my charges? And since I am at 36.5 of varget, should I continue to increase by .5 gr till I get pressure signs or until accuracy falls off? This is still for my 22-250.Thanks all for the help. Dan
