Have any of you used Hornady's SSTs in your hunting rifles? I put together a batch of 50 165s over IMR 4895 and got a ~1.2 inch group at 100 with my Saint .308 and a Sig Tango4 1-4x. That's a lot better results than I thought I'd get. I'm very happy with the precision from those bullets but effectiveness and mushrooming are unknown quantities at the moment. Have any of you used them to take a whitetail?
