360 Imperial Magnum

I have a 300 and 375 rum. The 375 needed a muzzle brake, they say life and recoil begin at 40. Recoil was brutal on the 375. One can acquire recoil tolerance, however, projectile over .308 is pricey. So its wallet or teeth rattling.

How is the 375 with the brake. The biggest caliber I’ve ever shot is the 9.3 x 62 and didn’t find the recoil bad at all. Mind you the powder charge is just about twice as much so a lot more horse power behind the same weight of bullet. Was wondering if I shouldn’t get a 375 RUM with a brake and see before I go down the path of getting an Imperial 360 built. There is a couple for sale that aren’t to expensive and if it’s not to bad then that way I would have a donor action and stock.
 
I use for hunting a 375 rum without brake. No problem. On the bench? Need a brake if more than 10 rounds in a row.
I’m a fan of big bore
 
Sorry to resurrect an ancient thread but I just blundered into a custom mauser in 360 imperial magnum down in Texas. Can anyone point me towards some reloading data. Also wouldn't mind surplus brass if there is such a thing.

Thanks in advance

I doubt you'll find any surplus brass for this cartridge. Should be able to make brass from 338 or 375 RUM brass though. Load data is out there but not much. As mentioned, I did some load development for Rembo's 338 Imperial. You could use 338 RUM data for similar bullet weights though, the larger bore should keep pressures within a safe range. These are boomers. Be prepared for substantial recoil, unless you have a very efficient muzzle brake. - dan
