Whats the proper OAL for a straight walled pistol round using a specific bullet. Duno, and neither does your manual. It's up to all of us to find the best OAL that feeds and functions in our handguns while staying safe. All handgun chambers and feed ramps are different and each one deserves it's own OAL.
This is where I start.
If it feeds and functions then I am done. If not I can only reduce OAL as going longer is not an option. Once I find the OAL that feeds and functions, I'm done, regardless of what any manual says.
What do you guys do to find the best OAL for your Semi-Auto handguns?
