Thanks for the info everyone. As my dad discovered long ago, Rem 7 1/2 and CCI mag primers are the ticket. I tried some IMR 4895 this week, I need to check this one out further, spotty groups at lower pressures but as it increased the gorups started shrinking, always a flyer tho...4 in 2/10 1 opens the group to 1/2", may have been the bullets though, they were Sierra 55 gr blitz. Most of my loads have been with 53 gr SMK and N201 and shooting around 3/10 ths. I do want to try 4198 and H322 though, I've heard good stuff about those two. I really have to find some smaller quantities of various custom bullets just to see if I can shrink the groups any. I'm gettin ready to re-bed the rifle with a Whidden bedding block, I talked to John yesterday and he walked me through the procedure!
My buds are still making fun of me though for fooling with the little deuce mag. I've got an 220 AI if I want to make horsepower though.
I am wondering about the viability of getting quality 204 brass and opening it up to 23 then back down to 22 and fireforming it.
It's all in the chase for smaller groups...

You probably can use the 204 brass{but it's going to form a tad shorter.
Remember to turn the cases and leave enough expansion.
Not too much though. It depends on your neck diameter.
Try neck sizing only and jump the bullets with the 4198.
The 7 1/2 is very good and we also used the cci BR 4 primer.
Now we have the new wolf mag primers to play with and i bet they work out fine. They have the hard thick cup
