Man, that is one stud cartridge.  Some of the loads call for 100 grains of powder for a 300 grain bullet.    My calculator emitted smoke while trying to figure out the recoil, mamamia,  they aren't kidding when they say ULTRA.  Sure would like to hear one of those loads fire off.  Keep us in the loop with progress, this is really interesting. 

Doesn't someone on HB load for this round?

I tried to load with Retumbo last night and the load was super compressed. Is that normal? I get compressed loads with my 300RUM, but nothing compared to what I got last night. Thoughts?

What charge are you using?  Where did you start? 

From Hodgdon website.
300 GR. SIE HPBT Retumbo 3.580" COL min 84.0 2501fps max 90.5C 2662 
  
300 GR. SIE HPBT H1000 3.580" min 82.0 2443 max 88.5C 2619 


Shows Retumbo to be compressed at max load.  I would have probably started at around 85-86 gr and worked up.  I don't load this cartridge but the basics are the same.  You have to find what your rifle likes and you start low and work up.  Sierra manual shows about the same.

Yes, I believe that round has some recoil.  I know what 77 grains of IMR7828 feels like in a 300 WinMag, 100 grains, man, and a 200+ grain bullet, on my, ouch.

Recoil is all relative... I would say that most people don't bother to try to fit their stock to themselves... and if that is the case, then a .308 could have the potential to hurt.

I don't know what load manuals you have, but I would recommend doing load development with a chronograph. With as big as that case is, it would be easy to overload a charge that doesn't fill the case completely. The chrono would make sure that you are in the correct ranges as you develop loads.

I know this is a real old thread but that is some funny stuff right there!

My younger Brother has a .338 RUM Remington 700 from the custom shop, he's a lefty.  He has had it for 7 seasons, shoots moose with it.  He is 6'4" and 260 ish and in pretty good shape.  I took him to the range last September so he could check zero before his annual moose hunt.  He shot 6 rounds of factory Rem ammo with a 250 gr Swift A Frame (no muzzle brake).  He put 5 in a 1-1/4" group at 100, I was impressed.  Then he sent one to the 212 yd fall away steel plate on the hill.  It knocked that plate completely over and tumbled it out of it's carriage. The energy is amazing.  He has shot 5 moose with it since new, none of them has taken more than 2 steps he says, most no steps. I have the bullet from his moose last year, it weighs in at 228 grs now. Realistically, they are cannons not hunting rifles if you ask me but, they are highly effective.
