Looking for some specific help with .45 ACP loads in a SIG P220.
I'm using:
SIG P220 Stainless
Barrel length: 4.4"
Case: Starline
Primer: Federal GM150M
Bullet: Hornady 230 gr. TMJ RN
Powder: Bullseye
Trim-to-length: 0.893"
C.O.A.L.: 1.270"
Taper Crimp: 0.470"
Dies: Redding Competition
Press: Forster
Chrono results:
Temp: 66F
5.1 gr. Bullseye: 714 fps average
5.2 gr. Bullseye: 741 fps average
5.3 gr. Bullseye: 758 fps average
All were accurate, no failures to feed/eject, and no pressure signs.
My Sierra reloading manual states a maximum load of 5.2 gr. Bullseye = 900 fps from a 5" barrel.
I was disappointed in the 741 fps I got with 5.2 gr. of Bullseye.
My question is: Has anyone safely pushed a 230 gr. out of a SIG P220 at say 800-825+ fps? Should I just stick with 5.2 gr. max and be happy with the 741 fps velocity?
Thanks...
Chuck
