That 308 I mentioned further back has proven to be the goods. I found a good load with 8208 at 44.7gn, CCI LR primers and a 150gn SST. I know some don't think a 3 shot group is valid, but I only shoot 3 shot groups out of light barrelled rifles for a couple of reasons. One, if you haven't killed what you aimed at in 3 shots you may want to try tennis, and two, sporting rifle barrels are a bit light, and heat up fast. As far as 10 shot groups are concerned, a waste of ammo.
