147 grain data is plentiful out there.Hello,
I'm looking to start handloading the.357 sig in a Glock 31. Would anyone have some handloads for 147 grain and/or 180 grain coated lead/ plated projectiles?
Thanks in advance for any advice.
My personal favorite uses Alliant Power Pistol and a 147 grain plated flat point bullet (X-Treme, Rainier Ballistics, or Berry's).
7.0 grains Alliant Power Pistol (7.4 grains max)
147 grain plated flat point bullet
Standard small pistol primer (any)
Crimp moderately, and bell the neck as little as possible
Exceptional consistency and accuracy.
I don't recommend 180 grainers, since you're going to have to load out to a far greater COAL, and the factory barrel isn't very tolerant of that.
