Hi, I was wondering if a nice chap with Quickloads can help me calculate some pressure ratings and velocities.
9mm , projectile is 147 gr Gold dot HP
Powder is Longshot, 4.8 gr thru 5.1 grains
COL 1.125"
3" barrel
Now, I do realize that from Hodgdon's website their max for this setup is 4.7 gr of Longshot but for 1.100". I was wondering if going 1.125" would be slightly more forgiving. 5.1 gr might go to a compressed load, also curious as to how +P a 5.1 gr load would be (will it exceed the +P pressure max).
Thank you in advance.
