I've had 3 300 RUMs and they are pretty potent but barrel burners, brass doesn't last, they kick the snot out of you, etc. My 30/375 S.I. holds 20 grains less powder but doesn't sacrifice enough velocity to put up with all the negatives of the RUM (IMO). I get great brass life, accuracy, and can reach nearly 3100' with the 215 Berger. It would work great in a 700 Rem., and in fact, a conversion from an already chambered 300 WM would be easy........Rich

That is what I am finding with the 300 RUM as well. I just finished load development on mine and it is accurate but you go through a lot of powder! I have a Sendero with a bunch of work done to it and with 91 grains of H1000 I am only at 2985 FPS. If you are getting 3100 FPS with 70-75 grains and the 215 HYBRID that to me sounds really good. I really like how accurate these 215's are.

I've never quite reached 3100', I think 3080' was the highest with Retumbo. I'll have to check the notes on charge, but I think it was around 82 grains? This is with a 28" barrel. H1000 maxes out around 81 grains with less velocity.......Rich

I like the results on your 30/375. The 375 ruger case is amazing. I did one of these in 338 and am getting 3130 fps with a 250 gr amax. With compressed loads. Do you know anyone who has done this in 7mm.

I don't know who has done one, but I know that PTG lists the reamer.

The Gunwerks 7 mm LRM is based on that. This subject has been covered a number of times in this post.
