Help with 6ARC loads please

[fatelvis]

I finally bought a complete 20” 6ARC upper from CMMG. Starlike brass and dies on the way too. Are you guys seeing any common accuracy loads yet? It’ll be just for informal target and shooting steel at distance. Maybe Coyote hunting occasionally.I heard Lever revolution is turning out to be pretty special in this cartridge. I have plenty of Berger 90s, Sierra 107s, but will buy more if you guys lead me to them. Thanks guys!

8208 is the Gold Stand for my 6MM Grendel based cases.

What weight bullets do you shoot using 8208?

I shoot 95s in the 243 LBC/6 GRENDEL in 500 yard F-Class matches. TOF vs BC computed better for my use.

Can you please expand on the "TOFvs. BC" comment? You piqued my interest!

I switched from 260 to 6 ARC for F-Class mid-range (600 yards). Don't forget the 105s from Berger and Hornady. I have been having good velocity from CFE223 but better accuracy from RL-16.

TOF time of flight was enough less over bigger bullets with higher BC ballistic coefficient at a slower speed to make sight adjustments less at distance. Plus the 95s are cheaper and more available. Another lighter bullet is the 87 grain Hornady in either configuration. I shoot those in 6X45 and 6X6.8 in F-Class with good results too.

28.1-28.7 grains of AA2520 with a berger 105 or 109 seated long. I shot a 980/1000 at a 1000 yard match at Reade with this in a 22” AR.

CFE 223 has been my go to so far. 30g behind a 90 to 95g bullet has been pretty accurate. Please work up your own load though. I’ve heard Alliant 2000MR is similar but haven’t tried it yet. A plus with ball powders is metering is good with most powder dispensers. Plus CFE 223 seems to be available most of the time. Sadly that factors into the equation now a days.
