I thought about lengthening the chambers to magnun length. This is exactly the same as the rimmed ancient .401 Herter's, or 1.25" cases. I think it's more trouble than it's worth to me. A 200 gr. bullet at 1300 fps is easy and all I need for this.

The 10mm is no cannon. A common .357 Magnum can push a 180 gr. at 1350 fps to equal the 10mm with greater sectional density. Not many consider this. Upping the ante to 200+ grs. helps. Ditto tough for the .357, I shoot the RCBS 200 gr. .35 rifle projectile at 1200 fps from the .357 revolvers.

Is the Ruger GP100 Match Champ. 10mm - WB, 2022-10-16, 11:32
