Just checked my Primer supply - 36 K of primers over 35K are CCI's. (all sizes, SP,SP Mag, LP, LP Mag, SR, LR, LR Mag) I have about half a carton of Remington's in LP.
And NO I do not want to sell any
Use to shoot PPC way back when and some of the shooters would turn out there strain screw on their bull barrel M10's. Had 2 Master Class shooters tell me that is the wrong way. Thin the spring, but never backout the strain screw - You could have a lighter hammer spring by thining it and still set off any primer. Backing out the strain screw caused the pistol to not have full use of the spring through out the hammer fall, thereby the hammer slowed down and you wouldn't get good ignition. You not only need to get primer ignition, you also need to get consistant primer ignition.
I use to load the 358477 with Unique and CCI SP. These Masters, with lightened hammer springs in their Mod 10 PPC guns would shoot the X ring out of the B27 with my loads, at 25 yards one ragged hole - at 50 they still stayed in the 10 ring with a high percentage of X's.
I couldn't and still can't shoot that good!
