What powder would you use in a 23" barreled .338 Win. Mag. shooting .225 grain Barnes X Tripple Shocks? I have been using RL 19 but I know you are fond of Hodgdon 4350. I have been using the 250 grain X for a number of years but I think they quit making that bullet and only make the 250 grain in the Tripple Shock version now. I trust your judgement.
