I use 23.5 grains of Accurate 2015 with a 52 hpbt sierra match bullet. this load is somewhat slow, so if you need a little more speed it could be worked up. Check your manual. Another good load for me in my 1-9 is 24 grains of Hodgdons H335 with the same 52 grain bullet. IMR/Hodgdon 4895 is another posibility. Kerwin
