I have an 8mm-06ackley and data is scarce and what is out there is old. Once the 8x57 brass became available there wasn't any reason to rechamber a Mauser anymore. Any way I use RP stamped 30-06 brass then fire form it I use 30-06ai dies with the neck bored out to 8mm. My fire formed resized brass is 2.473 long and holds 71 grains of water. I would love some starting and finishing point ideas on 125gr 150 and 170gr bullets. Maybe with a better selection of powders than currently available data( no new 8-06 for probly 20yrs) if any one would be willing to trade this favor for one I might be able to do for them I'd much appreciate it
