Will the older 336 actions withstand the pressure of the new 360 buckhammer?
I was wondering the heaviest published loads for my marlin 35 with 200 jacketed bullet is about 2200 fps. This is with a bottle neck case and yet this 360 with a mostly straight case goes 2400 fps. I wonder why I can not find published loads at a higher velocity for the .35 remington. I have some pointed flex tip bullets for it.
The 35 Remington max. pressure is 33,500 psi due to the autoloading rifles it was introduced in. It looks like they are running the 360 at around 50,000 psi.
Also, it looks like velocity of 2,400 fps is with the 180 gr bullet. 200 gr. bullet it 2,200 fps. which duplicates 35 Rem. load.
After looking at the cartridge drawing I think the engineers made a mistake. They have it as a straight taper from the base to the mouth with no parallel section to hold the bullet. That is going to allow the bullet to be seated crooked with no way to maintain consistency which will allow it to go down the bore slightly tipped and ruin any fine accuracy, especially when combined with a steep 12 degree/side throat with no parallel section and a 1:12 twist rate. This cartridge could have been a top choice for cast bullet shooters but I suspect it is going to be one of those "finicky" rounds once people start working with it.

Sorry, I didn’t mean to call your baby ugly. I was just sharing my opinion….this is going to be one of those “johnny come lately” cartridges lagging behind the 350 Legend, and getting ammo is going to be hit or miss. I can’t help but think what Remington did with the 5mm rimfire. There’s a reason why it failed…along with Remington itself not doing very well at this time.
50,000 psi….. will a 336 action handle that pressure ???
I like it, its not my baby, but I like all 35's.
You aint wrong, The previous "Remington" did have a crappy reputation supporting new offerings. I remember NOTHING about the 260 and just a flash about the 7/08!! But remember this is not "that" Remington. Time will tell if they follow the same Path. That page has not been written yet.

I doubt that this is really a problem. The round has a very slight taper. As long as the brass is first sized small enough, and then expanded using a plug (~0.356"), the ID of the brass at the front of the round will be adequately consistent to hold a bullet straight.
Also note that the wall thickness of most cases is thinnest at the mouth and thicker as you get farther back. They may have "engineered" this taper in wall thickness to get a more consistent ID than you would expect at first glance.
When I look at photos of loaded ammo, many seem to have that slight bulge at the base of the bullet. This indicates the bullet is being gripped by the brass along the full length that is inside the case.

Also, keep in mind that does not appear to be the SAAMI drawing (which would also include a chamber drawing). It may be an early "concept" drawing and just shows the taper continuing to the case mouth.
I looked at the SAMMI site and there doesn't appear to be a drawing for the 360 yet.
