[QUOTE="crkckr, post: 2917983, member: 78056"] Just a couple of things regarding 10mm in general. Firstly, never, ever go by what a factory powder looks like compared to what you might have on your bench! Unless the factory will tell you exactly what powder they use (kind of unlikely) going by looks is a disaster just waiting to happen! In this case, just say no! I've been reloading for well over 50 years and have reloaded over a million rounds of ammunition, having had a commercial operation years ago. I have by no means seen or done it all as there are a constant stream of new components on the market. Personally, having just in the last couple of years gotten into the 10mm (something I should have done 30 years ago when the Colonel said to) I am finding the 10mm cartridge to be the hardest of any other pistol caliber to judge the pressure via the condition of the fired brass! In this case looks really can be deceiving! The 10mm brass simply doesn't always show excessive pressure, in which case a chronograph is a necessity to keep you safe. If you're getting bulged cases, you are WAY over pressure, even in a stock Glock barrel! No if, and or buts! If your aftermarket barrel doesn't bulge a case with the exact same load it just means the barrel is covering up your sins better than a stock Glock barrel! It also means you're in the same category as a test pilot every time you pull the trigger... You're pushing the envelope with every shot and the only reason you haven't blown yourself all to hell and back is the outstanding strength of todays firearms! Unless you have access to good pressure testing equipment you can only go by chrono readings, which is a decent indicator but no where near as safe as pressure testing! Unfortunately, it is out of reach for virtually all of us in the trenches, doing things the hard way! I will also agree that using the extra heavy bullets in a 10mm is a case of diminishing returns.
