Home Forums Hunting & Shooting Custom Rifles & Wildcats Here's my 7mm Mashburn, show us yours!

That's what I am thinking.

I know Dober has some 180's but I haven't seen him break them out on the range yet through his Masher.

Here are a couple shots of Page's Ol Betsy that was for sale a few years ago.. I was hoping Bob would snag this old devil, but it went to another home.

I loaded some 175s up over RL26. Waiting for the range to reopen.

Excellent, I am looking forward to seeing that work. I haven't ever found the 175 Partition to be hard to get shooting. I used to use RL22 and the 175 Partition in my old 7mm Rem before it became a Mashburn for around 2950 and it was accurate, but Bob got in my head and told me if I like that, I'd like the same bullet moving a 100 FPS faster!

He weren't wrong!

If RL26 doesn't perk I'll give Retumbo a go.

I'll be happy with 2950 or better.

I'd bet money that 7828, H1000, Retumbo, 26 or a few others, and maybe RL23 if you can find that will get you there.

Roger that, a lot of good choices to stretch it out with, i'll be plenty happy to hunt with these 160 AB's till they're shot up, may look at something different then, LOL, Ol Betsy looks like a cool piece too.

Damn Fed-X truck ran while ago, just got through planting three rows of beans, my damn back is killing me, each bean seed one inch deep, three inches apart with rows two feet apart, AYFKM? , the things we do for our women!

As a rifle looney issue I understand the appeal of the 7mm Mashburn, but if I needed more than a 7mm Remington magnum in a Remington 700, I would go get a 7mm Weatherby in a Weatherby MK V. Let the flaming begin.

That is the easy way if you like Weatherbys and freebore! Matter of fact, I have used a bunch of 7mm Wby data to get started with the Mashburn.

I am not that familiar with the 7mm Mashburn ballistics, what does it actually gain over the 7mm Weatherby? I'm not trying to be argumentative I'm just not that familiar with the round.

The Mashburn has no performance advantage over the 7 Weatherby, or 7 Dakota for that matter. The case sizes for all three are just a touch bigger than the 7 Rem Mag. I consider 7 Weatherby data as a max velocity for the Mashburn. Amazingly 7 Rem Mag max charge loads in my Mashburns usually outperform 7 Weatherby book velocities.

The advantage of the 7 Mashburn over the 7 Weatherby is brass availability. There are several sources of high quality 300 Win Mag brass and less availability, at higher cost, of 7 Weatherby brass.

But if you are willing to get the 7 Weatherby brass it’s a darn good round. Same as the 7 STW (brass availability), 28 Nosler (one source of brass, availability), 7 RUM (availability), 7 Dakota (one source). They are all good rounds.

Then there’s the wildcat thing. Advantage or disadvantage depending on the person.

I understand the brass availability issue, but in the age of ordering brass on line I don't think that it's as big an issues as it may have been in the past. Another point in favor of the Weatherby is while it doesn't matter when hunting in the United States, when hunting overseas, other countries customs people may want the ammunition head stamps to match the markings on the rifle barrel. No I agree that the cost issue between 7mm Weatherby brass and 300 Winchester brass is real, but considering the cost of assembling a custom chambered wildcat rifle it's a bit of a reach for my sense of logic but it is a rifle looney thing.

You aren't wrong at all with any of your points and if you are concerned with any of them a standard Wby is pretty much your man.

Some of the best Mashburns out there are rechambered 7 Rem Mag's to be honest. For a 100 bucks (to rechamber) and a set of dies you are into a Mashburn. The Mashburn gets speed from maximized case space while the Weatherby dotes off of freebore. It's a pick your poison sorta deal. No wrong answers just different ways for getting up the hill.

Beretzs, you are correct, I was thinking of having the rifle built from scratch, I didn't consider rechambering an existing 7mm Remington. In that case it's just the cost of rechambering ($100) because the cost of the dies is a wash, Mashburn or Weatherby.

I recommend that to anyone that just wants to try one out. A quick rechamber on a 700 is really good since you can seat bullets where you want them. A 70 needs a 3.6 magazine and a shortened bolt stop.

A reamer like Matt Hoffman’s or Dober’s would work well in a short magazine though.

I have a 700 CDL SF in 7 rem mag. THe reamer will clean up the chamber on that gun? If so I am interested.

Oh yeah, easy peasy. My old one I pictured on this thread has ALOT of teenager hand loading learning shots with H870 through it and 18 years extra on the barrel. Once the smith took it back and thread and rechambered it, it was like a new barrel. I was blown away how well it shot as a rechamber.

Thanks for that info. It has flutes so they probably have to index those as well.

They will put it back right OEH, since they take a thread off it seems like it goes right back to where it belongs.

Methinks Beretzs has had the Mashurn standard passed to him from Bob
