Double js338 RUM data
I have a 338 RUM and have been looking for a secret recipe.

Does anyone reload Retumbo for this cartridge and what's your suggestion for a 225gr bullet?
My neighbor swears by his Retumbo powder. I haven't bought any yet to try out.
Thanks in advance, JJ

tradewindsI just started with Retumbo today, 95.5 Gr. Retumbo, 225 TSX, F215M, 3.60 OAl shot the best 3/4" group. Should be a little over 3000 fps.

Double jsThanks tradewinds!
The cool thing is that I use the same type of primers and I bought 2 boxes of Barnes 225gr TSX for this gun.
Thanks agian, JJ
