I tried 220 grain SP Hotcores over TAC today. 49 grains clocked around 2,520 and shot very well. Unfotunatley, there were feeding issues, every third round or so bound up instead of chambering. Perhaps seating depth changes might help?
Cases were Win with Fed 215m primers.
I have had good luck with 49 grains of plain old IMR-3031 and 200 grain Hornady SPs. Cases are Win again and primers are WLR. This loads reaches 2,660 and shoots around 1-1.5 inch groups in my Ruger Hawkeye.
I have yet to try it on game but really like the rifle and cartridge.
Several people have mentioned forming cases from .308s. Win and Hornady both make .358 brass. It can normally be found for around $30 for 50 cases.
