With the 14" Pistol,
I got 1801, 1769, and 1751 (3 shots over the chrono) with the Hornady 220 gr FP. no doubt one could do better (ie, faster) with optimizing, but my load was with 30.0gr IMR 4198, new 375 W-W Brass, and CCI Standard Rifle Primer and OAL of 2.500"
Use load data at your own risk.
Load data came from Hornady Manual 4th ed.
I was satisfied and didn't bother to mess with anything else.
