Desire to build a 300 RUM

Thanks for all the feedback, considering the math (Build Cost) I am researching the cost of a custom price. This was one of the recommendations

A RUM built with a 9 twist along with an action and mag box capable of a 4 inch round is the way to get max performance out of this round. I load mine with a COAL of 3.99 and seat 245 Bergers about .020 off the lands on top of N570. with a 25 inch barrel it gives almost 3000 fps (2996). Great perfomance out to 1000 yards farthest I have shot it so far.

Absolutely zero negatives building on a trued REM 700, they are one of the best designs ever and why they are copied to the 'enth degree.
Done correctly, you will have a rifle that is just as good as any custom action.

Except for low resale, no integrated bases, no integrated recoil lug and won't accept prefits and that's after dumping a pile of cash into one getting it trued, the primary extraction fixed, milled to accept longer mag boxes, the optic base holes straightend and opened up to 8/40. You do all that and a 700 is almost a custom action and the 700 only cost slightly more.
 
I used to shoot a RUM. It's a great round the only issue is making it mag feed with the heavy bullets.
I ended up going to 30 Sherman Mag for this reason.
 
I don't even bother having the action trued on a 700 anymore. For what it cost once done I could be at custom action with more features and prefits. I still use a ton of 700s and have great luck with them. I'd just run the 700 as a single shot and get it throated long.

Hey they accept Remage :p
 
My buddy did a build on a browning x-bolt. Proof barrel Boyd's stock in a 300rum. The action is great for the money and more gunsmiths will work on them than you think. He can load out to about 3.750 I think in the mag. Only downside is aftermarket support but with McMillan making stocks now Id build one in a heartbeat.

If that is your priority then don't use a $400 action and true it. Truing a REM 700 is pretty simple, I used to charge $250AUD for this service and $500AUD for chambering and barrel fitting to said action.
Mine cost me parts and time, and I could care less that they don't have integral bases, recoil lugs or bolts without primary extraction issues. All of mine have #8-40 base screw holes, first thing I do.
The parts I buy and use are all PT&G, complete one piece fluted bolt, .250" or .300" recoil lugs, Wyatt's bottom metal and Trigger Tech trigger now that Jewel are no more. Bases/rails are dependant on purpose.
Cost for me is a little less than a custom action by Borden or Bat, I am NOT in the US, so my costs are way more than yours in every way. Import fees, tax, customs agent fees and the import/export fees, the list goes on and on…

Cheers.

The bolt bushed, pin and spring updated, ejector/extractor and likely a new bolt handle. Not counting the side bolt release if you want it.
I know firsthand.

The 700 action works just fine as stated. By the time you true the action, cut it for a 4" box, and put in a PTG bolt, you are really close to the cost of a defiance classic that is ready to go. You can sell the factory 700 bolt and recoup some cash but in the end you still have a rem 700.
Go full custom :D

That stand to reason. A good point!
 
I turned my Rem 700 300 RUM into a 7 LRM. It was always a good shooter, and I thought the recoil was quite mild for the cartridge, but I had an itch to build something different. I didn't do anything with the action, put on a McGowen remage barrel, and the rifle is a laser.
A buddy always gave me his brass from his 300 RUM, so I am well stocked for my 338 Edge.
That same buddy bought himself a 300 PRC for his 40th, and the RUM has sat ever since.
