Bet those would be sweet on a tikka action. Wonder how they'd feed on a 700
What 7mm magnum cartridge to build?

The 7WSM is one of the fastest pin prickers around. Too bad the brass is hard to find.
Yep, that's why I responded as such in #21.

you can run a Wyatt Center Feed BDL set up or go with a M5 inlet and contact Hawkins Precision about their hunter magazines and spacer kit. That would give you 3.350 of magazine length and feed great. 7SAUM w/ 180's seated properly, WSM variants, or the 7x6.5PRC

The fact that you can't find great 7WSM BRASS is upsetting. I would love to have one built myself.
Did you mean to respond to me? Because I am not the one needing the information. I find it a waste to do all the mods to a RUM LA to accommodate a 7MM SAUM, instead of using a more appropriate action as I stated in #21. And yes, I have 7MM SAUM. as well as WSMs.
Most comparisons between 7RM & 7PRC came to the conclusion that if you already have a 7RM, no need to get a 7PRC. If you are just starting out, they both are good choices, but if you want heavy commercial ammo, go with the PRC. You can do anything you want if you are getting a custom barrel with twist and throating, but if you have to pick up a box of ammo at the local LGS, the off the shelf 7RM ammo will be a disappointment. I love my 7 Sherman Short (and vibes with your less powder theme), but in a Long Action, it is a waste. I have no experience with the Mega or Max, but it seems they thrive in the Medium (XM) actions vs the Long. I think the LA and less powder with a Mag bolt face is an oxymoron. In short, with your setup and criteria, 7PRC.

Maybe a sherman 7? MEGA, MAX?
Love the case design. Brass dies available too. Best of luck

Another vote for 28 Nosler. Brass is widely available .. and Graf's usually keeps Peterson 28 Nosler brass in stock. Same case diameter as RUM so your action's feed lips should work great. And the 28 Nosler case is a quarter-inch shorter than a RUM case, so you should have no hassles with COAL.
That said, the 28 Nosler is a pretty big case ... about 20% more capacity than a Sherman Mega or 7MM Rem Mag. Personally, I like having that extra case capacity ... no need to push pressure to get extra velocity.

Derek has a new "long reamer" for the 7 Mega.
The earlier options were. 146 and .205
Mine just got the .235 surgery.
Fired case diameter .551 at the .200 line
