What barrel length and loads are you using to push the 230 grain OTMs to over 3000 in the 300 RUM. Just curious because the fastest load I can find in the book is 2790 with 88.2 grains of Retumbo out of a 26 inch barrel. I have been looking to load these in my RUM.

I am running 2970 in a 26" RUM and 3020 in a 28" with CCI250 / H1000 / Norma Brass and 230 Hybrid Targets. I got around 100 fps faster with N570.

89.9 Retumbo, 215M, RP Brass, Mag length, 2980fps
RL 33 goes crazy when the temp gets above ~84F, and runs pretty dirty, but is a great choice if you don't have hot summers
