I definitely wouldn't shorten the Mighty RUM. I'd install a Wyatt's extended mag box.
If you are going to neuter a 300 rum just get a 30 Nosler.
I drive a lot of magnum rifles. Almost all have brakes, which is the worst shock for scope fasteners. I've had more than one sheared base screw before I decided to only wear stress free bedded quality one piece bases and lapped scope rings.
If you ever lap a set of scope rings you'll be...
Yeah, I have built a couple all on DPMS gen 1 upper and lowers. My current 6mm CM is 12lb. 3oz. unloaded! That's with a carbon fiber handguard!
It is however a tack driver.
My 300 RUMs absolutely do not have weatherby freebore. I'm seating. 020" off the lands.
Almost all Weatherby cartridges freebore is .375". !!!! I think a couple have .285" or something.
How's your sfar shooting?
My 20" SFAR will be here next week. I loaded the FGMM receipe 175gr SMK 41.7gr imr4064 and gm210m primers for break-in.
My experience with ar10/ lr308 gas guns it will probably take a couple of hundred rounds to break in the barrel and mechanics.

Just ordered a 20" SFAR. I loaded the (re-engineered) FGMM load. 175gr SMK 41.7gr imr4064 and 210m primers for break-in and sighting in scope.
My experience with lr308/ar10 rifles, it takes a couple of hundred rounds, plenty of lube, and several barrel cleanings to break in the rifle.
We'll...
I feel sorry for the literal millions of new reloaders that started loading because ammo was scooped off of the shelf. They dont know only two years ago primers were $30, Hodgdon 8lb was $210.
I've seen people at the range that I've tried to get into reloading as far back as the Obaummer...
I will suggest cleaning the bolt and bolt lugs really well. Re- lube with Moly grease on all moving parts.
Get the chamber inspected with a borescope for rust. Polish if necessary. Use a small base full length size die If your reloading.
Make sure handguard isn't binding or touching the...
Since I inherited my dad's 742 30-06 I have spent quite a lot of time mechanically restoring it.
After several load development sessions I believe that I have had a breakthrough.
150 Ballistic tips and Reloder 15.
Shot at 200 yards from a hunting bag.
I can't believe that I am exited about...
I have a "Pelican" copy from Harbor freight. This thing weighs 26lb empty..
I slipped a disc in my back carrying it and two scoped rifles up stairs from my vault!
