50 AK Number 1

[potatojudge]

I have a No 1 customized to 6.5 Swede with a bull octagon barrel. I don't need a bench gun and it's 11+ lbs as is. 24 inch barrel, but that could be cut back easily for better handling. 

I already have a No 1 in 45-70. I load for the 500 Linebaugh. 

What are y'all's thoughts on having JES rebore it to 500 L or 50 AK? I'm thinking weight reduction plus a caliber that really benefits from the additional barrel weight. It's got a new stock that will handle the recoil well. Is there another cartridge you think would be better suited?

Since you already load for the linebaugh, I vote for 500 Maximum. While it can't match the 50AK, I'll bet it would be pretty impressive.

I had that thought, but if I read correctly the 500 AK chamber will shoot the Linebaugh and I have the option of loading it without trimming brass to 500 Max length. If you can't shoot the linebaugh out of the AK chamber, that changes things.

[coldtriggerfinger]

The 500 Linebaugh was made from the 348 Winchester case. Which is the basis for the 50 Alaskan also. So yes the 500 L. Could be shot in a 50 Ak chambered rifle.
What twist is the 6.5 barrel ? How many rounds have been fired ?
6.5 Swede is a really great all around round.

I'd go 50 AK. I talked to Ben Forkin about an 1895 Marlin in 500 Max and he said just go for the 50 AK.
Makes sense.

I don't know the round count and I haven't measured the twist. The Swede is a great cartridge, but I don't do a lot of bench shooting and for me it's better suited to a lighter platform. I bought it a few years ago from a fellow who's father had it built and left it to him. I assume early 90's/late 80's build based on the skip checkering and that being the style of the day. It came with a cheap Redfield scope that popped the first box I fired so I can't say if it's a shooter or not. Haven't re-scoped it. Assuming it is a shooter I still don't have a need and would either sell or rebore it.

[coldtriggerfinger]

Is there room to move the extractor over ? The breach block / loading trough might need to be enlarged.
What would you have it twisted for? Jacketed or cast ? Sounds like there is plenty of steel in the barrel even with a half inch hole in it. Would lighten it up some to make it funner to pack around.

JES recuts the extractor, rechambers, and rebores for $225 or so with a 2 week turnaround time.

I'd tell him 4-500 grain lead and let him pick the twist rate.

Kelye, that's a great looking gun. That recoil pad is serious business!

I've long thought a No.1 RSI in 500 Linebaugh would be a wonderful thing.


I wouldn't want one in 500 AK. It would either have to be brutal or too heavy.

i have a 500L in a tc encore with a 23" MGM heavy barrel. i shoot 450gr lfn gc with a charge of either hs-6 or 2400. though i am still trying to find a load for her, its a 1 1/2" at 100 yards(5 shots/benched). 

i'd stay away from 500AK, it goes faster but the penetration is the same as the 500L.

Not necessarily. The .500 Linebaugh verus .50 Alaskan penetration test everyone cites is from a Linebaugh seminar way back when. It was one test and isn't enough to draw hard and fast conclusions. I built a .50 Alaskan on a Siamese Mauser and shot oak tree sections with my 585 gr LFN cast from linotype. At 2,000 fps they repeatedly penetrated the sections in full. The same bullet at 1,500 fps would not. I know the new trend with big caliber bullets is to write down velocity. But doing so challenges the time proven law of momentum (the popular Taylor knockout factor is predicated on momentum). Kinetic energy cannot be ignored and it is transferred to the object. Furthermore, higher kinetic energy widens the wound channel. Contrary to Dr. Martin Frackler's writings, hydrostatic pressure/force is very real. Many ballistic studies prove the point and directly debunk Frackler's theory. Do most folks need the power and recoil of the .50 Alaskan? Probably not. But it has significant and useable horsepower over the smaller .500 Linebaugh.

thats a nice rifle.
but i don't like the recoil it has.  i use a recoil table and a recoil chart to see if i can shoot it or not. the 500L(i think its 8-9lbs) using a 450gr lfn gc and hs-6 or 2400 is around the same as the '06 using a 180gr bullet(around 20lbs of energy). also i'm disabled(stroke gots me, right arm/leg are 20% good), so i like 500L  and its recoil. now i won't be going into the brush so i can take out the grizzly bear in close quarters . i'm more of a deer/black bear guy that sits in his blind.

now the 50 ak and the 500gr bullet's recoil is about 50lbs of energy(i think). that is a recoil monster on my arm!!!   

i don't believe ft/lbs on game is relevant, sorry. i believe in a long or wide meplat and slow speed will take out game. my "speedest" round is a 30-40 krag that pushes out a 165gr ranch dog(25.5gr of h4198) that goes a whopping 1800fps. i can't say about the penartion, but it goes thru deer at about 150 yards or so. its a 10 coww to 1 tin. 

i ain't smart enuff to do the stuff you and others do. my head  goes blank when you say "my rifle does does x ft/lbs". i'm comfortable with a meplat and reduced speed.
