Not Bob. Just run 300 Win mag brass in a FL die. Skip the trimming. No neck turning required. Depending on the reamer of course. Case life is excellent.

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! 00 3700fps with a 120gr Barnes TTSX out of my 26 inch tube. Will begin playing with some 139's and 140's when I am feeling a bit better. Looking forward to the experiments and shooting.

GG: Dave and Safariman are right. It can be done with just FL dies.In fact the first dies Redding made for the Mashburn were formed with brass from my rifle for dimensions. They thought only FL dies are needed.
I use the F/T dies, because I already have them but have done it both ways. Either method works.

I was and am too cheap and broke to buy a set of 7mm Mashburn dies, but my rifle will eat up and fire just fine 300 WinMag brass run through a 7mm STW FL sizing die. From that first form down, I merely run that same die back a few turns and neck size only.
The 7mm RemMag to 7mm Mashburn Super conversion is SO easy, and makes SO much sense, I hope and think that we will be seeing this done to more and more vanilla 7 Mags.
If anyone has any experience or data for the 7 Mashy or the nearly identical 7 practical and 7mm/300 WinMag with 120-140gr bullets pushed fast, I would love to see it. H4831 got my Barnes 120's to 3700fps but I have done precious little testing or development other than toss together that quick load for a soon upon me deer season and call it good enough. My hope is to get the higher BC 139-140's out the snout at 3500fps, (from my 26 inch octagon barrel) safely and with good primer pocket life.

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? Is this something like what your looking for?
Want To Buy; Form die for a 7mm Mashburn Super. .284 Hornady AMax 162gr. .224 Hornady AMax 75gr. 22-250 bushing die Bushing die that will work with the 7mm Mashburn Super A couple Glock 42 380ACP mags

I'm the weakest link in the chain, someone really knew what they were doing when they put it together.
Wanted: Vintage Remington or Winchester hats, patches, shirts. PM me if you have something.

Can a Ruger 77 MK 2 action in 7 MM Rem Mag be Rechambered to the Masburn the action mag length is not as long as a Rem as I recall. Or will mag length be to short?

Or will mag length be to short? kk: With the caveat that I haven't done it, if a 300 Win Mag fits an action, a Mashburn should. Bullet seating will be deeper.This will bug some people and others not at all. Since I use M70's,and others Rem 700's it makes sense to use as much action length as you have, which is why my M70 has a 3.6" box.

Took the words right off of my keyboard I think a Model 77 in 7mm Mashburn Super would make a fine hunting rifle. If the rifle is already one of the various belted magnum chamberings, should be a really easy switch to make.

Thanks for all the info guys, I really appreciate it. Should be starting my build in January.
Thinking an Edge ADL, bolt fluted/hollowed by Kampfeld, Talley LW's, and a 3.5-10 vx-3 with M1 ele.
Then sending it to Mr. Fosnaugh for Cerakote.

I'm thinking west in the future for hunts. I'm still young (20), got lots of life to live yet. But my heart will always be in Maine, and I'll always be here. My 375 H&H and Guide Gun got me covered for Maine pretty handily. You can thank Beretzs for leading me to the Mashburn. I was thinking LRM, but then saw the light of day.

I went the lrm route and later regretted it. Had lots of pressure issues and brass issues and it never consistantly shot well. It also didn't seem to have anymore capacity than a standard 7 rem. It looked like a good idea and works well for some but I wish I would have spent the money on a mashburn. I just got sucked in by the beltless lrm.
