Thanks fiver, I'm just kicking things around as I get an idea.
That 315 mold has a meplat that is nearly as large as the 31141 mold I used to have. What would your opinion of the 315 as a deer load be? I took several deer with the 31141 in a 30-30 that also went down the road. I've been shooting a few leftovers from that project with some success in the 308. These were water dropped and LLA tumbled. 100 yard groups under 1.5" are pretty common, some are close to 1", just have some flyers to 2" that make me think I'm close, but not there yet. None were weighed or too closely inspected for flaws in those days. I've been seating to engrave the full length of the front band, maybe varying that depth will help with the flyers. I've thought a time or two that a new 311041 from NOE or Accurate and PC it for nose diameter might do the trick.
Not really hung up on the bore rider, just what I've got to work with at the moment.
I've got some of the RD SC311-165RF loaded with 29gr 4320 to try if this wind ever lets up, maybe the PC and subsiquent water drop out of the oven will help make up for the plain base. File the coating off the nose and it checks around 20-21 Bhn on my Cabin Tree tester. 1.43 Sn, 2.92 Sb alloy tested by BNE
About the only slower powders I have on hand are H4350, H4831sc, a little RL-22 and some MagPro. I haven't tried them since I always heard the slow powders could be trouble if downloaded too far. The fast and midrange powders are what I stock the most of. Benchmark, TAC, 4198, H4898, one can of IMR 4895, Big Game, RL-15. Varget, Norma 202. Probably left out a couple. Plus my shotgun powders. Solo 1000, International Clays, Universal Clays, Longshot, 800X. Probably a good thing the wife hasn't seen the inventory in a few years.
