Actually I am reloading a Winchester M1917 with bullet hpbt of 167-168 grs with good results, have been using Sierra , Lapua and Nosler with practically the same results, since the barrell has a rifling of a turn in 10", I would like to try the 175 grs. Does anybody ever tried such a bullet , and what is the suggested reload charge ?( please only IMR powder since is the only american powder easy to find here in Italy)
