Home Forums Hunting & Shooting Custom Rifles & Wildcats The 7mm Mizzum

Was thinking about Cole's first lope trip five years ago... the old Mashburn whacked and stacked lopes in style.

And your shooting wasn't too bad either... (grin)

Yeah every once in a while a blind dog finds a bone...

Seems to me you whacked a lope that day, and got whacked that day yourself..

Thanks Scott! It was tough choosing an action, but the M70 was all I had lying around........

Skane has pics of the 7RM and Mashburn compared,both empties and loaded rounds.Sure he will post for me when he sees it on his email.....

Hell,why I am I doing all this explaining?.......Dober is the Mashburn guru.....not me......I'm the "student"

Dober you walked me through this project....thanks! I have mostly not shot anything else since it showed up!This thing is almost the most fun you can have standing up

BTW, I tried the FF method Steigers and RinB schooled me on....result is perfectly formed Mashburn brass,which I loaded with 75-H1000 and 160 Partition.Going to the range with it now.

That one of them there controlled feed jobbies? What's that about?

Been looking forward to hearing about this Bob.

Congrats, that's a great looking rig.....although I'm kinda surprised you didn't go with a McSwirley

ny: I left the stock color up to Gene and D'Arcy...I think it came out nice!

Bob,
Would love to see some additional pics of the rifle!

Nice project Bob.
Good when a plan comes togeather.

Dave:Workin' so far.....wonder how it would do with a GS Custom?

Thanks, Brad.Handsome is as handsome does and near as I can tell so far it performs nicely.Being a rifle "student"(always learning),and a bit of a history buff,it's an interesting cartridge to me and fascinating when you think about how it got started....and how well it turned out in a day when folks did not have access to the info and technology that we now have;even Warren Page had to send cartridges and rifle to Remington to get the velocity info that any of us can get in an afternoon now,on our own.

Tastes in cartridges shift like the wind and guys are constantly running around to newer,different cartridges.I think a lot of this activity is circular, like fish swimming in a barrel,and lots of new cartridges are not all that "new";the design or performance parameters having been set decades ago.The Mashburn is a good example of that....witness the "new" 284 Jarrett,or the STW.

Goes to show you can't really know where you are unless you know where you've been.....

I thought it was poetic justice that my first shot over the chronograph with a 175 Partition measured 3050.....precisely what Page said his old rifle did at the Remington plant back in 1959....


And yet there is newer good stuff today.....personally I think the 6XC should replace the 243 in short action sporting rifles....just a better, forward looking design.And old Bill Steigers told me the other day if he were looking to build a hotter 375 than the H&H round,he would not bother with his old favorite 375AI,but would move right on up to the 375 RUM with its' good, modern brass and plenty of capacity..

.....this from a guy whose clients were blowing out 404 Jeffrey brass and necking it down to 30 caliber a couple of decades before the 300RUM saw the light of day...interesting to think about and there ain't much new under the sun!

It would be a boring old world if everyone shot a 30-06!

It's great to read of the enthusiasm that another rifle can bring.

Superb writing such as BobinNH's and that of others makes it so enjoyable.

Your Mashburn would turn 120g GS-HVs into screaming missiles of destruction.
It would work just fine Bob.
They also have a 140g GS-HV but im not sure that your 1-9 twisted barrel would do the trick.
Person would have to call.
The lighter bullets dont seem to be theme here in this project.
Betcha a 120 grainer wouldn't kick as much as the stuff your shooting.......


dave

Dave is 9 twist too slow for the 140?

I figured I'd give it the traditional stuff for now

1-9 should be just fine short of a javelin.

A bit confusing.
Gina could clear that up in no time.
The 140 HV should work fine.
As monos they are long for caliber.
.... A 140 HV out a a Mashburn......


dave

I'm guessin' the same
