I've been shooting 100gr of bh209 with a 250gr tc superglide with good results. For the limited gain in velocity that you get going up to 120gr, it does'nt really make much sense and the 100s more comfortable to shoot. I just recently tried something new. I bought a box of hornady 250gr ftx bullets, the ones for the 450 bushmaster. Matched them up with a harvester crush rib sabot, and a winchester primer. This combination shoots a very tight group out of my encore, and even works out being a little cheaper bullet wise.
