Not to hijack the thread, but I'm looking for a starting...or accurate load using RL15 and a 210 grain bullet. Info seems scarce...just bought one of the 20" barrel rugers. I'm presuming roughly 50-53 grains...but found someone online who was up to 58 grains...seems on the hot side. Any info would be appreciated. Have a bunch of Swift Scirocccos I want to play with.
