New 6mm ARC on the way

[2brothers641]

Ordered a Seekins DMR 6mm arc today. Should have it in a few days and want to get a head start. What is the consensus on best mags, preferably 5-10 round? Currently I don’t reload so factory ammo for now. Any of the factory offerings showing consistently good accuracy? Rifle will be primarily used for hunting inside 250 yards. Thanks for any input.

Duramag 10’s and 20’s run great in my Seekins ARC. All 3 Hornady loads also hammer in it. I mostly shoot precision hunter because it’s a great hunting and long range bullet in one.

Some states require 5rd or less for big game with a semi auto.

No capacity limits here. I just like shorter mags for hunting, especially when using a thermal at night.

I’ve had good luck with Duramags in my .450 BM so I’ll give them a try. I see Geissele has some mags (not in stock). Christ they are proud of them for what they cost.

I think that barrel has a 1:8 twist vs the more common 1:7.5 twist rate for 6 ARC. Some people find better accuracy with lighter bullets, but they also handload. You can try the 3 Hornady offerings and see what it likes best. Seems the 105 Hornady Black and 108 ELD-M are the most available.

Currently using the duramags. 10, 20, and 27(?) I believe. The 20 feels like it really only wants to hold 19. You can shove 20 in there but good luck inserting it on a closed bolt. All have worked flawlessly for me so far

How’d the duramags work out in your rig?

They have been flawless so far, many hundreds of rounds later. I barely use the 27 because it’s so large and awkward shaped. I haven’t had a mag related cycling issue yet. They even work on full auto

I've had no issues with the 6ARC-specific ASC mags (ones with red followers) in my Seekins DMR, if you want another option, too.

From what I've been reading, most of the 5-10rd mags feed pretty well. It's the higher capacity (20rd+) where the issues start popping up for some reason.

I have about 600 rounds of 6arc through my ASC 6.5g mag. Probably about that in grendel through it too.

Been using ASC grendel mags for 22 ARC, zero problems.

How do u like ur DMR?

Duramag, E-lander, ASC, and Geiselle ($$) all seem to work pretty reliably in my experience. There may be some upper/lower tolerance fit issues that cause one or another not to jive so well but if everything is made right and you have a good mag catch those have all been solid.

I've seen some stepped mag catches that drop the magazine position lower cause issues and I don't really know why someone would make such a thing but they do.

Because the cartridges are so short and fat they do not stack well in the larger mags, so they get out of alignment and jam up.
5s, 10s & 20s work the best.

Have ASC and Duramag for my Seekins. Both have worked fine. Love that rifle.
ELDM has been pretty consistent. Happy for now
