Does anyone know a 'smith that has a 7 mashburn reamer that can clean up a 7 RM chamber on a 700?

PTG doesn't list it on their reamer list, yet I've seen where they have been PTG 7 mashburn reamers sold in the past. Do they have a reamer print for it and you just need to call them?

GG I am pretty sure Gene Simillion has a reamer.

Also PM Dave7mm on here. I think his smith has a reamer but don't know the smith myself.

The place that rents reamers (and thier name escapes me right now) has one as well as the nearly identical 7mm/300 WinMag.

PS GREAT idea and caliber choice!

Any idea on PTG though, do they make one?

I believe PTG has made a few

I remember now the name of the place that rents reamers. They are called 4D gunsmithing supplies and they rent out Reamers and other gunsmithing tools that a 'smith would only need from time to time.

A number of years ago I rented a 300WBY reamer and a T-handle for it and re did a Browning A-Bolt chamber from 300 WinMag to 300WBY Magnum which turned out wonderful. Beginners luck I am sure but with care and lots of cutting oil it can be done and they will help you by renting you the tools to try it yourself if you want to. If you mess it up, you have only screwed up a factory Model 700 barrel and those plus aftermarket specimens are easy to come by.

Best of luck whichever way you go.

One more option. I have a Hugh Henriksen reamer that was used to do one chamber that I will put in your mailbox for $150.

Buy your reamer then sell it. Have the smith cut a Wilson seating die with the same reamer.

Bull's-eye

Yep, a rented reamer may have done a bunch of barrels before you get it. Even if re sharpened not as good as a fresh one IMO. And, you can probably re sell it after use for about what you paid. The 7 Mashburn Super is a fairly popular wildcat with easy to make brass and a significant performance improvement over the two other more common 7mm Magnums.

Would really like to purchase my own reamer. Not ready to buy yet, just gathering info right now.

Not really sure which way I'm going on dies yet. Are the 7mm Mashburn Super Magnum Short dies that RCBS makes the right ones? Not sure what short means? Was thinking about buying die blanks and having them reamed out. Would I need a separate reamer for that?

This is my reamer from PT&G, I'm sure the numbers at the bottom right should be able to help them.

GG: Yes that's the one. There is some confusion in the name but that's what RCBS calls it for some reason.

Art Mashburn actually did 3 7mm wildcats on the H&H case; one was intended for 06 OAL like a 7 Rem Mag, the other on the full length H&H case (like the STW),and the 3rd, more notorious one we are talking about here, the 7mm Mashburn Super, which was intermediate in case length.

Your Rem 700 is an easy conversion and should require nothing more than a rechamber. I know a few people who have done it that way.

I notice you're from Maine....too bad we didn't know. You coulda swung by The Forks and seen mine. I had it up there in November.

PS...just build (ream) it, you won't regret it.

JR that turned out nice!

That looks like a fantastic rifle.

I have a 24" on my 7 RM currently, but I also have a brand new 26" 7 RM take off as well. When I get ready to do this, I think I'll have both barrels set up at the same time. Really looking forward to seeing what this can do. I'm currently trying to create a Quickload file for the Mashburn off of some reamer prints I've found online.

Bob, that's too bad. I'm actually down near Bangor.

GG: Mmm...Bangor wasn't that far

All barrels I am familiar with have been 24" IIRC. Not sure what a 26" will do but I bet it won't be bad at all!

Bob which do you feel is a better method of making the brass; form/trim dies and then fire forming or, just running it through the FL die and then fire forming?

Also any neck turning needed at all?

How is case life once they have been formed? Assuming you don't step on it too hard.

I appreciate it.
