Now, don't change a thing with OAL, crimp, bullet, case or primer. Reload each of those cases that are now fireformed, (neck sizing only) Load each of those loads with .3gn less, and .3gn more (look for pressure signs as you shoot the warmer ones). Test fire again.
Then... and I think there's a thread on bullet seating depth here somewhere, then you get to play with OAL to find the absolute most accuracy. And not to knock the Accubond, but there are other bullet choices that may prove to be more accurate than what you're shooting now.
You could still sort the fire formed brass with a case concentricity guage after you've neck sized...
RL22 may prove to be better for you, but you don't know for sure yet. I tell ya... I've got a load that is a bit on the warm side, with 4350 pushing a 180gn Speer SBT at 3100fps that is a tack driver, but the same load pushing a Sierra BT match bullet is erratic as hell. Drop the charge a bit for the Sierra match bullet and it's even more of a tack driver. But alas... Not the velocity and trajectory I'm striving for. So, even though its accurate, I don't load it. (I didn't buy a magnum to be shooting 30-06 performance) Anyway... All I'm trying to say is work up your best loads with each powder and keep a good record book so just in case.. You can't find a particular powder some day, you'll still have something to fall back on. I've got loads for multiple powders and bullets for my primary rifles.
