To update, the EBR Thumpers shot like crap in my rifle. For now, I'm considering the Hornady Custom lite 125 SST load. It's actually quite a bit quieter in my rifle compared to full power loads, and still is greater than 1800 fps to 300 yards, so it should expand nicer while keeping the power lower to avoid total destruction. As a bonus, it's extremely accurate. The bad BC (estimating 0.28) shouldn't limit me too much for my short ranges. Now to grow a pair and actually TRY it to see if I wake anybody up.
