I am reloading for a Browning Bar Light weight Stalker. Have been shooting Rem. 150gr. Core-Lokt for about 8years. For some reason round are like a 3” group at 50 yards. I have some 150 grain and 165 grain Hornady SST. Wondering if anyone is reloading for the same rifle. If so what bullet and powder combination are you using? Thanks in advance.
