Late last year news started leaking out about a new Remington cartridge, it was introduced at the shot show this week. The 360 Buckhammer.

A straight taper case 1.8” long based on the 30-30 case with a .358” bullet of 180-200 grains.

I couldn’t think of any thing exact but, somewhere between a 38-40 Remington and a 357 Herrett.

Henry is chambering their single shot and lever rifles for the cartridge.

Not too many rimmed cartridges released lately, but with the new straight walled cartridge deer hunting rules in few states, there might just be some renewed interest in rimmed cartridge development. 
Maybe even some interest in single shots.

You missed the other most likely reason to fail, Remington put it on the market. They kind of have a tradition of not supporting what they introduce.

Still. it is interesting to see a rimmed cartridge being developed. Not much innovation going on for lever guns and single shots by major manufacturers.

Because in some of those states they had a 1.8" max length, and the .38-55 is over 2" long. But many states relaxed those rules where a .38-55 is now approved, so this cartridge is already not needed in those states, or the rest of the US.

I take a different view of the cartridge:

It is interesting that it's based on the .30-30 that's SAAMI pressure max of 42,000. Wonder where the other 8,000 came from?

I understand this was designed for those states with their silly straight-walled case rule  , but let's face it, the neglected 356 Win. is/was a much better cartridge, especially as a hunting round.

Nothing is actually doomed,.
Especially when someone takes something like that out, fully develops it for him or herself.
And then starts winning allot of the matches with it and then everyone now also has to have it !!

Basically what they did was legitimize the 35-30 wildcat and give it saami spec in hopes of competing with the 350 legend for the Midwest deer hunting market. It will be interesting to see how it catches on with that market as well as if intrepid single shot shooters start messing with it and get good results.
