6ARC - Go to loads?

[centershot]

Any super accurate go to loads? Been struggling to find a really good load. Several are consistently under 1" but finding that magic load has eluded me. Preferably bolt gun loads in the 87-105gr range.

I've got Tac, Cfe 223, Starline brass, 87g vmax, and 80 TTSX. Just waiting to put the final touches on my Howa and some warm weather...will let you know!

6mm ARC 1:7 twist, 26" SS Douglas barrel. 1" groups at 300yrds. using old ww760 mag primers and 95gr Berger moly bullets. 2845f/sec. velocity
What have you for a rifle,

That's a long barrel for a micro action cartridge. What action are you using? I'd think you'd have gone with a larger case unless you liked the powder economy of the ARC.

this is an experiment. Winchester model 70 26" Douglas air gauged barrel with a 11* crown. No Brake. Timney trigger. Night Force scope. I have had it in 3 different stock. Its in a laminated stock for now. I'm going change things up for spring. Set up will be for a new McGowen Barrel for 1000yrd. bench rest. I have 2 Barrels a 6.5 284 and a 300WSM for heavy gun. Sorry centershot didn't mean to hijack you thread .

87gr V-Max, 28.0 LEVERevolution, CCI 450, Hornady Brass, 2.160 (.020 Off Lands) in my Howa Mini - finally stumbled onto a load that is producing <1/2" 3 shot groups. 2575fps Need to load up a few more to verify but looks very promising. 28.5 of the same looked good also with just a slightly larger group then 29.0 to 30.5 blew up to ~1 1/2"+.

Mag primers were quite a bit better than 205M's

FWIW: At right around 30gr I am getting compressed loads. Not sure I could even get the 32.3gr max load from Hornady to fit in the case.

Seems that I have to be at the low end of the loading data from Hornady to get decent accuracy and not have pressure signs. Upper end loads (and factory ammo) are very hot in my rifle (stiff bolt lift, brass swipes, ejector marks on brass). I have been starting about midway in the load data and going up, with this rifle I think I'll start over (with other bullet weights) at the very bottom of the bolt gun data and work up from there. Accuracy is my priority, dinging a steel plate out to 5-600 yards - doubt I'll ever hunt anything bigger than a coyote with 6ARC so max velocities really don't matter to me. Will keep exploring other loads, bullets, etc but it is nice to finally have a bench mark load for what the rifle is capable of.
