I load 96 grns of Retumbo behind the 208 A-Max at 3150 with the primer slightly starting to flatten. Cases are on the 6 th loading. this is in a sendero with factory barrel
seems like everybody wants to run at or near max. I realize big magnums run best toward the top of the load chart but my rum loaded around the middle of the spectrum doesnt seem to have any trouble keeping up with friends loaded to the max. we are shooting steel from 500yrds to 1200yrds.just my observation.
95 Grains of Retumbo, Fed 215M primer, Rem Case, 200 AB...... as well and 3208 average. No pressure signs either. Don't really know much about reloading and I even think your numbers are very high!
