Shot 58.5gr of H414 (medium-hot load) with 225gr AB's and TTSX's in my 338-06AI to fireform the 338-06AS Weatherby brass. Impressive 0.5" groups so far breaking-in the barrle/fireforming brass. Now to up the powder.
I have several powders and was going to try H380, 4064, RL15, maybe WS780 - I use Federal 210M primers- not mag primers with my loads... Told didnt need it.
