Not all 10mm loadings are equalBought a magnum research 1911 in 10mm,,
This is my first bull barrell,,and im surprised how nice the recoil is,,,not much muzzle lift,,,and not much different then 45acp..
For decades Blue Dot & 800x was me go to heavy load powder. #7 was my "regular" powder.Power Pistol is my 10mm powder. I was looking at velocities today, 165gr Speer HP, 1350 out of my RIA 1911 10mm. IMO, PP in the 10mm is like Win 296 is to the 44 magnum.
