Question about cartridge likeness
Jun 24th, 2024 at 10:21am
Print Post  
My question is about the 35/30-30 and the 360 Buckhammer.
Are they the same cartridge ?
Asking because I have a Stevens 32 cal that needs a re-bore. I was going to send it to Jess to re-bore and chamber to 35/30-30 but it is a wildcat .  I was looking at the new last year from Remington the 360 Buckhammer.  The stats say its parent case is the 30-30.  As for resale value it would seem more wise to chamber to a factory cartridge.  I have to wonder are the two 35/30-30 and 360 Buckhammer the same ?

Something to consider; Can the Stevens handle the pressures from the 360 Buckhammer?

Keep on hav'n fun!

Chamber pressure specs for the 360 Buckhammer are 50,000 psi max.  I would be using a Stevens 44 1/2.  Do you think that is acceptable ?  
My loads will never be close to that max but the next owner of the rifle might use factory ammo.
I would still like to know if other than acceptable pressure are the two cartridges dimensionally interchangeable ?

Thanks for your thoughtful consideration for the next owner.

The Stevens 44 1/2 action has been chambered for high-pressure cartridges and held. CPA offers their action in .225 Winchester that is a 50,000 pounds factory cartridge.

The problem is quicker wear, and tear, on the action.

Yes, no, maybe is the best I can do.
Besides the 35-30 Maynard, there are a couple wildcats based on the 30-30 case. One is a bottle neck, one is a straight taper. As far as I remember, they use the full length of the 30-30 case. 

The Buckhammer meets the definition of a straight wall case, but is tapered. The 30-30 case is shortened.

I don’t think a Buck hammer can be chambered in at least one of the wildcats, due to body diameter. 

You would have to sit down with one of the cartridge conversion books and match measurements.

For me, the answer would be NO! The Buckhammer case is only 1.8" long.

2 things:
I'm sure you could get at least 100 fps more, out of the 35-30/30 or the same with less pressure.

I think you could probably shoot the Buckhammer cartridge in the 35-30/30 chamber,since it should head space on the rim, unless they made the rim much thicker, to keep that from happening.

CPA can’t be compared to an original.  The CPA is a heavier frame, wider by .125 I think, and better steel.

Its not that I am looking for high velocity hunting performance .  I am only looking to restore the accuracy of my rifle.
I would be loading only cast bullets from a velocity of about 1300 fps on the high end to subsonic on the low end. 
Perhaps it would be better/safer for a future owner if I went with the 35/30-30.  So stamped the barrel would indicate hand loading only.  If some future inquisitive owner would care to try a 360 Buckhamer in a wildcat chamber that would be entirely up to them. On the other hand if the barrel is stamped 360 Buckhammer it would invite the use of high pressure factory ammo.  I think the 360 Buckhammer is out and either the 35/30-30 or the 38-55 is in.   Thanks to all.

Do not compare the pressure handled by a CPA replica 44 1/2 to an original 44 1/2. 
The CPA version is made 1/8" thicker and is more capable of higher pressures than the original Stevens 44 1/2.

I have an H&R handi rifle that I rechambered from .357 magnum to .360 buckhammer.  I've only test fired a few rounds in it so far until I put a scope on it. You could certainly load down the .360 buckhammer, and mark the barrel .35 1.8.
Here's a pic of a .360 buckhammer cartridge next to a .30-30 cartridge.

Not an answer to the question at hand but why not just step up to the 38-55? Solves many questions and concerns. I think it would impact value to  lessor degree then the afore mentioned suggestions. Maybe there is an issue I am not seeing, but I can't think of it.

The one issue I have with 38-55 is brass availability.  I am thinking that if I go to 37/38 caliber in a factory chambering I might prefer the 375 Win. With that I can make brass from 30-30 which is quite easy to find.
The pressure issue does come up again though but not as much as with the 360 Buckhammer.
I assume that since the 375 Win is chambered in conventional lever actions that its pressures run in the neighborhood of 40,000 psi which is 10,000 psi lower than the 360 BH.

The SAAMI pressure rating for the 375 Win, is 55,200 CUP. Same as 308 Win.

those Winchester rifles were NOT the 'conventional' guns the .30-30 used. The ones that Marlin made were stronger than a Stevens rifle too. Maybe keep it to the .38-55 and stop the silliness of looking for a solution to a problem that doesn't exist.
