I have a 7mm rem mag and wanted to rechamber to a 7mm RUM and was wondering how to open up feed rails?

you shouldnt need to for a 7 rum, but it you do its best to have a competint gunsmith do it.

i take that back, you may need to i didnt realize you had a 7mm REM mag. cheapest thing to do would be sell your rifle and buy one in an ultra mag, might loose a couple bucks on the deal but itll be cheaper than modifying your current action. if you do that all you need is a $25 wyatts extended magazine box and a barrel and reamer, I also reccoment spending the $30 on an over sized recoil lug

I would use the action that you currently have, no sense in selling and loosing money just to get wider feed rails. Talk to your local smiths, its an easy mod on a mill. Last year I rebarrled my 243win to 270wsm and my smith charge $25 to open up rails and install a Wyatts extended box.

What about your bolt face? Was opening that up included in the $25?

As I said in my previous post, it cost me $25 to have my rails opened up and extended box installed. I had another bolt for the wsm. The 7rem mag and 7 rum have the same boltface dia, so I'm not sure where you are trying to go with this?

I was simply asking you a question about your bolt face. I didn't say anything about the 7rem/7rum bolt face. You made it sound like you had $25 in getting your action modified to take the wsm case that's why I asked about bolt face. And even $25 to open the rails and mill back your bolt stop is a bargain. Machinist usually charge $60 ish. Per hour around here and that is more than an hours worth of work in set up and labor.

But aside from this bosstom Guy trying to be more right than anyone else. All you need is to have a Smith open them up which shouldn't cost a ton and I reccomend having him mill your bolt stop And installing an extended magazine box also.. or like I said before just switch out rifles it may be a little cheaper than Smith work. Check into it and see which way is cheaper...
