.50 Alaskan barrel twist rate and diameter at chamber/muzzle?

[EG73]

Hey guys,

If one was to have a .50 Alaskan built with say a 22” barrel (round or hex) what diameter should it be at the muzzle and chamber region?

Also twist rate? The guy makes his own barrels in 1/8, 1/13, 1/15.

a 1-15" twist should be more than enough and as far as barrel dimensions, what action are you going to use? I had a Pedersoli Sharps rebored to 50 AK by JES so chamber/muzzle dimensions have plenty of "meat". Now, an 1895 Marlin might be getting fairly thin.

I had a Browning- Winchester Model 71 converted ( rebore of factory barrel) to 50 Alaskan, and cut short and handy to 16.75”. The barrel is fairly thin at the business end.
Also had a Ruger no 1 bored out and trimmed as well it has much more meat than needed, but the extra weight is welcome for recoil.

The 1895 Marlin is a Wild West Guns Conversion, and is about identical in thickness to the M71, although the marlin is a 20” barrel. Recoil gets a little sporty with bullets over 500 grains, but as it’s such a large diameter straight wall case, it’s easy to keep the pressures down. The heavy barreled No 1 is chambered a little long to accommodate 50-110 cartridges, which is the next step up, and as a single shot can use more aerodynamic projectiles. The brake, although not pretty really helps with shoulder pain.

That muzzle brake is well done and about as discreet as you can make one. I have an Encore barrel from Match Grade Machine that isn't 'subtle', as the barrel is stainless steel, so the holes are pretty obvious, but it was finished so well I was about to return it, because "I wanted a removable muzzle brake, so I could use a suppressor". Then literally as the phone was ringing, I saw the faintest line in the finish and realized it was indeed removable.

Speaking of such - what's the PISTOL chambered in...???

Sorry, yeah a marlin 1895. Maybe even a 20” barrel. For some reason Alaskans are usually built shorter so I’d like to do that also. If I ever get a .50-110 built it’ll sport 26”.

Some nice rifles but does anyone have any muzzle OD’s?

[Bearskinner]

Those 4 in that pic are all 50 Alaskans, including the 12” pistol ( with a huge brake as well) the Winchester and No 1 will take 50-110’s, but realistically a 500 Linebaugh Maximum ( they cycle well in the lever guns) will go thru a Big moose, Bison, or do a Quigley on hogs. I like pistol recoil z lot better than rifle recoil. There is just something magical about those huge cartridges dropping in a chamber!

Don't know the dimensions, but when Lee Martin documented his build on a Siamese he used a Pac-Nor blank with a 1-18" twist. They'd probably tell you the external dimensions.
