As of this post, they got the 1Lb'ers in stock.  They had 8Lb'ers but are gone now.

Sierra has discontinued 6 MM bullets on sale, free shipping and no sales tax.   They have a moly coated 55 & 70grain Blitz King and a 90 grain FMJ.   The 90 grain FMJ might make some good shorter range plinking and target ammo.

Man, after reading this article Id expect firearms chambered for this round to sell very well, except. Except Ammo and component shortage may squelch sales. Interesting read on reloading for the 6mm arc in both gas & a bolt gun. 

After reading this  be giving the propellant IMR8208 XBR a fair bit more consideration in my bolt action when she is put together

anyone have experience with these?  https://americanreloading.com/en/243-6mm...500ct.html

or these 85 gr bullets?  https://americanreloading.com/en/243-6mm...500ct.html

They have the 105s available, as of a couple minutes ago....

Anyone tried making 6MM ARC brass from 22PPC?

I have 200 NOS Norma cases.  Still having trouble finding ARC brass.

Kind regards,
Pavementends

My first hand loads were Hornady 6.5 Grendle brass sized to 6 arc, CCI 400 primer, Nosler 105 RDF, and Lever started at 27.5 grains seated to 2.280.
The 27.5 load worked o.k. but primer cratering occurred.
at 27.8 accuracy was good (.610 for three shots) but the third shot popped a primer.
I have a good supply of CCI 400's, but only a few of other makers as the reason I started with them.
I would like to hear from others that have used the CCI 400's in the 6 ARC, perhaps with more success with lighter bullets or other powders.

What happens if an AR15 and a 6mm benchrest rifle make babies?

The 6mm ARC.

Back years ago the naval surface warfare group created a rifle that extended the range and accuracy of the standard service rifle by creating the MK12 SPR (special purpose reciever, later called the special purpose rifle).
This slick piece of gear paired with its MK262 ammunition , with a 77gr sierra matchking OTM was capable of extending range out to as far as 800 yards in some enviromental conditions. It also had a harder punch on anything it hit than the standard service rifle.

The 6mm ARC opens the possibility to take that concept a step further by extending the range to or beyond 1000 yards, in a rifle thats approximately the same size/weight as the SPR.

It hits harder, its range is greater, and it can be more accurate in varying enviromental conditions such as wind and sea level air density.

Considering that it also packs enough energy for hunting, and uses a cartridge thats very similar to 6mm benchrest cartridges, i think this currently represents the leading edge in MSR type rifles that can be made with off the shelf parts, firing factory available (if the shortages would ease up) ammunition.
