6 mm Remington

[Red-ass]

These days, finding any brass which suits your cartridge choices is favorable. This is especially true with those cartridges which do not enjoy all the hoopla of newer cartridges. The 6mm Remington does not now enjoy any of the accolades showered on the 6PPC or the 6BR or any of the other 1/2 dozen 6mm wunderkind cartridges. So it languishes on the sidelines because of being ignored in favor of more dollars, faster from the manufacturing of those cases with more notoriety and higher sales figures. So it goes. Many cartridges can claim the same.

If you can't find 6mm Remington brass you just need to join the ranks of those of us who rely on converting other cases. Currently I've found .257 Roberts +P, 6.5x57 Mauser and 7x57 Mauser without having to use the resources that I have stocked up on in the original case.

I do understand that most reloaders glorify Lapua brass as being the pinnacle of quality and when they can't find the cases they want by that manufacturer, they believe that they are taking a step down. That may well be. But...

I've been using Remington and Winchester brass in 6mm Remington for a few decades without any drawbacks. Do I get 15 reloads from each piece? Nope. But I rely on recipes utilizing newer, modern powders which burn cooler and at lower pressures.

Sometimes we just have to dig a little deeper to find the brass we can use.
Kurz, good post , over the years I have found out if I anneal case after 3 shots, it gives me more case life. Since I have right at 300 case`s and rotate them they should last a long time. Only thing is that after 6 shots in a case, the annealing lets the neck stretch and start cracking but even then still get at least one more shot out of it .The load that I use which is hotter than books suggest using the WLRM primer takes it up to 41.2 grs. w/W760, it`s the only powder that I have found to shoot accurately in any Rem. 6mm I have ever owned. (Rem. 721-Rem788 and now the 03A3/Shaw BBL.). What gives me the edge w/hot loads is I Moly-coat all my SMKHP-107

I see alot of post about Rem 6mm brass. When I could not find it, went 7mm brass. The 6mm was designed off the 7mm.. Anneal it, Lube it run thru full length sizer, if needing trimming, then fire form. Fire-forming will smooth out any crinkles in shoulder, ck trim lgth. and go for it. lol.
Been shooting Rem 6mm for alot of years. Started with 788, finally shot out the barrel. It had old twist 1-11.
Best load for it that I found was Rem. brass-WLRM-40.2grs.-W760. Push old SMK-70 over 3k, won alot of match`s with it out to 400yds. lol
Now I shoot Rem. made 03A3 action, Monte Carlo Stock, Timney Trigger, Shaw 1-8 26in. heavy barrel. With 36x Gold Ring, 1/8 dot. Use the load of 40.2 grs. WLRM W760 pushing 107SMKHP-107 gr. at 2865 fps. I moly coat all my match bullets Could push it faster but at my age lol at 407 yds. cutting same hole so reckon I`ll leave it alone.
P.S. The darn thing will only shoot Rem. Brass. Here is the proof.View attachment 1503351
