jmoore. I have been getting real good results with my reloads. With Sierra 180gr. SP I was able to get 1/4" group at 50 yds. and the same bullet shot very good with IMR4064. I think you will need a heavy bullet as the 150grs. don't do as good at least for this rifle. I hope to get to the range and do some 100 yd. shooting. The sights on the T-99 are not too bad either.
