Tell me about the 6mm Remington

[C-Money]

I saw a like new in box M77 in 6mm Rem the other day. Really nice rifle that sportsmen just don't find very often anymore. The rifle is chambered in 6mm Rem. Me being a big fan of the .243 win, this cartridge sounded like a fun project. I've read and watched most all the info available on the interwebs, and it was entertaining. Please share anything you want about the 6mm Rem, hunting stories, reloading recipes, on game performance...I've began looking into brass and ammo costs, and they are a bit high. Looking forward to the possibility of a new project.

I’ve seen deer shot with both, and all died quickly. I’ve never seen them used on elk. I can’t imagine in there’s a noticeable difference in performance for hunting.

Check the barrel twist.  The old / original 6mm Remington's came with a slow twist and could only stabilize light bullets.......thus the .243 was invented (at least what I have been told as the main reason the .243 was born).  I'm sure if it is a newer production 6mm Remington, it will have a faster twist barrel....likely a 1:9.  The old production 6mm Rem's had 1:12.  If I was building one, I would want a 1:7.5 or 1:8, but the 1:9 is more than adequate. 

If you end up buying it, I may have a bag of brass laying around you can have.  I can double check and let you know for sure if you get serious about buying it.

I had one in the mid 1980's and used it on several Blacktails, but no elk.

Used Remington C/L 100 grainers and was very effective at the average ranges here in Western Wa.

If it hit bone like the shoulder, it seemed that the damaged/bloodshot meat was reduced a fair amount and they tended to drop in place.

Through the lungs and there was always some tracking involved, but not more 50-60 yards for a long track.

On paper, it was just a touch "Bigger" than the .243 and shot very well and consistent with mild recoil.

With the advancement in bullets available today, it could be a very effective and fun round to play around with.

What's the difference between a 6mm Rem and the 6mm Creedmore? I bought an Encore frame a few years back that came with the 6mm Creedmore barrel. I know nothing about it.

Brass was hard to come by for a while PPU brass is available.  Buy it and a couple bags if you big game hunt and cant make it.  It makes fairly easily from 7MM Mauser and 257 if you want to shoot varmints.  Good solid round for up to medium size big game.  You have to be careful about overheating the barrel shooting prairie dogs, but it is as good as anything.

I have a custom 6mm built on a Mauser action with a Douglas Premium varmint weight barrel.  Love it. I deliberately chose it many years ago after lots of research.  I killed several deer and a few black bears with it and loaned it out a bit and it killed one 6x6 bull elk.  I mostly shot coyotes with it. A son likes it and it is his. 

I worked up a Hornady 75 grain hollow point for coyotes and 95 grain Nosler Partition for deer and bigger.  The Hornady would shoot all day into a 5/8” circle and the Nosler into one ragged 3/8 inch hole.  I don’t know what the twist is.  The 6mm case is slightly larger than a .243 case.

If you have a magazine and chamber long enough to allow full use of its larger case, then the 6mm is about 100 fps faster than the .243.  A problem is that most factory rifles put the 6mm into a short action that does not allow many bullets to be seated out far enough to take full advantage of the larger case.  Short, lighter weight bullets solve this if the rifle shoots them well.  Otherwise you basically have a ballistic twin to .243.

I'm very positive the 6mm rem will become part of the family....I'm thinking the barrel is a 1-9 twist...as it is a 84 as far as I can find. Thanks for the replies...

Pro tip.  If it is a factory barrel stamped 6mm Remington it will be 1:9 nearly without exception.  Maybe w/o exception. If it were 1:12 it would be stamped 244 Remington.  IIRC, the 244 was reintroduced in 1963 as 6mm Remington.  The only change was from 1:12 to 1:9.  The 100 grain Partitions are marginally stable shot at 244 velocities with 1:12 twist.  Elevation and barometric pressure can cause them to shot great at home ranges and not worth a darn when hunting.  IIRC, Nosler came out with 90 and 95 grain Partitions to have a great bullet available.

I can remember when I was a kid in 1960’s our next door neighbor had a 244 Remington. He used it for deer and elk. That was when you could shoot spike elk. He used his 1950 Chevy car  to hunt from as he didn’t have a truck. He could get all the pieces and the spike head in the trunk of that car. Had to tie it shut. Lots of memories of dad hunting from his car

My grandpa had one and I believe my uncle probably has it now.

All of us grandkids used it for our first deer, cousins kids etc. I am now curious how many “first deer” that rifle has killed, easily 20+

High grade wood stock that you never see nowadays, thing was a tack driver with minimal recoil.
