I've been trying to sort out a good common load for all five of my .30-30s and finally may have it. The problem is (of course) is each rifle might as well wear a different cartridge designation due to vast differences in throat, bore dimension, and headspace. I went back to my Lee group buy commercial copy of the 311041 with the lovely little .305" band at the nose base which makes it SO much better than Lyman's. Of course I powder-coated them to bump the nose up to .3025" for the Marlins. Final sized to .310" as a compromise fit. Coated them this morning which knocked the BHN down to 8.5, but I'm impatient and decided tobshoit them anyway, a nice mild 30K PSI load of Reloder 7.
I took the sloppiest and tightest rifles of the bunch and got them on target at 75 yards with the new loads, then on to 100 for some groups. Since the Marlin only got 2.5" I loaded five more at a grain less and shot the 1-5/8" group. The 1899 with peep and bead did about the same with the 23 grain load and me just aiming somewhere in the middle of the paper.
Now to go gas check and coat a bunch more and let them age out to try again, then get the rest of the fleet sighted in for the load.
