Anyone care to share their favorite or go to loads for the 6mm Remington. I have a Cooper mod 54 montana varmiter, 26" 1 in 10 twist. My best groups so far seems to be with the sierra 85gr HPBT and 39.5 gr of IMR 4320.

For years, my hunting partner and I, shot a 95g Nosler partition with a max load of IMR 4831 and a 9 1/2 primer, bullet liked to jump just a tad, 3150 fps. We shot a lot of big Nebraska White Tails with this load at some yardage. Today, I would try the R#26 with a fed 215. We both sold our 30/06 after shooting this 95g partition, and for some reason, the 95's are more accurate than the 100g partions when we tried them.
IN the early to mid 80's, For chucks we shot 85g bthp, 38.5g of H4895, Fed 210 at 3100 fps to 550 yards.
On coyotes we shot a hot load of 42g of IMR 4064, Fed 210, 80g Sierra blitz at 3500 out of a 26 inch barrel with short freebore. This load has the loudest "plop" of any bullet I have ever heard shot on coyotes. Even when shot in the stomach, the coyotes are laying in their tracks stone dead.
We shot hundreds of coyotes in Mexico with 50g of Win 760, Fed 210, 60g Sierra at 4000 fps, bullet never fails you, the bullet is too fast to hear a plop sound.
Superperformance will accurately shoot 80g sierra's at 3600 out of a 26" barrel, reported to me by a close friend, also with R#19 with a win primer.
Best accuracy attained with all the above loads was with the bullet just barely touching the lands, with the exception of the 95g partition.
IMR 4064 with fed 210's and 70g Noslers will give you some incredible accuracy and velocity, 39.5g is a good place to start, No flies on 760 either.
I had a reamer ground with zero freebore, no turn neck shooting the 60g through 80g Sierra and Berger bullets into bug holes with Shilen SS match barrels using 12 Twist barrels.
The 6mm Remington is an outstanding cartridge capable of incredible accuracy with speed.

Varmint load: Speer 70-gr TNT, 54 grs (max) Superformance, 3800 fps. Dial it back to an accuracy node, it'll still be faster than whatever's in second place.
Don't try CFE 223, there's a reason Hodgdon doesn't publish data for it in 6mm Rem - it's unstable and therefore dangerous. Yet its fine in both 243 Win and 243 WSSM (the virtual ballistic twin to 6mm Rem).
PS
Teaser: H4831 is a little slow for light bullets in 6mm Rem, Hodgdon now omit it for bullets lighter than 90 grs, but they did published it in their 26 Edition down to the tiny 60-gr bullet. So I did an initial work-up with Berger 74-gr MEF Moly some years ago:
Berger 74 MEF Moly
WLR
H4831 SC
Hodgdon cited max 50 grs yielded 3369 fps, middle of the pack velocity. Here is a single 4-shot group I shot at 100 yds with 50.1 grs of H4831 SC (I did not clock it) purely FWIW ('67 R700 Varmint Special, absolutely box stock, the first year of production!) It may have accuracy potential.

My 6mm Rem likes 4831 & 4350 with the 105 & 108 Berger twins.

Same question here. I recently scored my "bucket list" 6mm Remington: a lightly-used Cooper M22 Varmint. Will be used for varmints and coyotes at this point, so lighter bullets will be focus.
Although it didn't come with a test target, those I'd seen from Cooper 6Rem/.243 Wins were shot well using 70 gr. Sierra Blitzkings and relatively fast-burning H322(!). Nearest to that on hand was Benchmark; with 39.5 gr., Hornady brass/9 1/2 primers in a stiff breeze, all 5 were same hole or touching vertically as barrel warmed/fouled. Not sure of the mag length of your repeater, but OAL of these were 2.825."
Following these, I shot some 70 Nosler BTs, to their book load/length of W760 (45 gr.) at 2.770". Thinking they were completely missing the target, when I retrieved it and counted holes through the backboard, I was shocked to find they had exactly the same p.o.i. as the other brand bullets loaded with a much-slower powder and significantly longer OAL! Weird, but I'll take it. Was so happy that I forget to chrono, but these are mid-point loads; with the 26" barrel length should run around 34-3500 fps.

I use IMR 4895 behind Sierra 75gr HP bullets in mine. 3480fps. Fast and very accurate.
Just built another 6mm Remington, but haven't even broke the barrel in so I don't know what load it's gonna like yet.

Wow lots of good ideas from everyone, thanks. I'll try some of the different powders mentioned like H4831,IMR4064 and IMR4350. As far as bullets, I guess with a 1-10 twist I should probably stay away from the heavy bullets like 95 -107gr. This rifle should shoot as well as my 700VS 308 (1/2" to 3/4" consistent) but for now it doesn't. This may be due to a problem I'm having with bullet runout on loaded rounds. Working on that problem now. Thanks again to everyone for their comments and suggestions.

The main thing is bullet length. You could shoot a 100gr conventional bullet just fine but the vld bullets need a faster twist
The 87gr. Hornady shoots very well also.
I think the 87 vmax and HPBT would both be good candidates.
