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.
