Man, you have some FUN toys! And lucky to have a spot like that 3 miles from the house. Actually, I sold that 7x300, and built my first 6.5 PRC. The PRC stayed super to 2K as well, but did it with even less recoil, and a lot more barrel life.

I am a fan of the 7RM having worn out three of them so far, but if building I would look at the 7mm Mashburn or the 7mmx300 win. with the Mashburn being a better design due to a longer neck.
The 280AI is another favorite and the Rem. 7 SAUM is a better designed short version of that capacity case. Not sure I buy the inherent accuracy claims but it is similar to a PPC on steroids and no doubt as to it being accurate. Possibly more accurate than the 7RM with fewer magnum velocity swings. I would put it in a medium action or even a long one and twist it for up to 195 grain bullets although I would probably use 160-180 most of the time.

If you go Mashburn, have the smith cut the leade angle at 1.5 deg. That has improved accuracy on my last rebarrel.

I have a 7mmSTW reamer and have built (3) of them. I have (2) 7mmRemMag reamers and have lost count of how many I have built for myself.
My personal belief is that the best long range gun that weighs 10 pounds for a guy with poor shooting skills, like me, is a 7mmRemMag

Nothing...and try finding ammo for the .28 Nosler at a local Wally World store, should the need arise.

If a short action is desired, I can't see beating the 7 WSM. Also, for a hunting weight rifle, 180g x 3000 fps is about all the recoil I want.

Anyone have any idea what a 175 grain could go from a case holding 109 grains of water to the mouth? Let's say with a 26" barrel.

Any cheap way to get 7mm Weatherby brass? That is main reason I haven't run one yet. Can easily be formed from 300 WM brass, but if going that route I would probably do the Mashburn or 7mm x 300WM with the Mashburn as frist choice due to a longer neck. You can also re-form 7RM brass but it will be short.

30. you can make 7mm Wea. brass from 7mmRM.. Just run it into the die and form it and shoot.. It will be a bit short but will grow with time.. It is one of my favorite 7,s.. Had an STW no Mashburns or 7mm-300's I might look at them if I were doing this all over, but I am not.. Good luck..

I hope so! It’s pretty much the 21st century Mashburn! Rick will keep building 270’s and knocking stuff down and forget about it though.

WhelenAway If I wanted a Big 7 I would get the 7-300 PRC. However, I have used a Big 7 on seven or eight plains game hunts and I couldn’t see any increase in effectiveness over a 270.
The primary original reason for magnums was to increase range by flattening trajectories. LRF’s have changed that.
If I wanted to shoot animals at LR and wanted a light portable hunting rifle I would pick a 30/06 or a 338-06 over any Big 7.
I am convinced that bore and weight are important.
Actually the 30/06 is a really hard hitting big game cartridge.

That's what I figured Rick. But once in awhile your posts have me thinking you're gonna wander off the 270 reservation again, so I figured I'd check

I don’t think the bigger 7’s really come into play till you’re out past 400 yards myself. Up to that point the good old 270 is pretty tough to beat. Especially with the sleeker bullets coming out for them everyday.

My choice would be the 7mm Remington Magnum.
