Jeff from CMMG announced in a brief comment that they are moving to SAAMI II (SPC II) chambers and 1:11 twist. They already had the SPC II chamber, but the twist is a change from their 1:10's.

It sounds like the intro is down the line some when production catches up, as we've seen in the rest of the industry like RRA's 1:11 barrels.

They already have "extended feed ramps" listed as a feature, so I'm hoping their ramps are good enough for the 90 grain loads that are hanging up in Stag 6.8s. If not, I think I'll start a Dremel rental company and become a site sponsor. 8)

thats good news the more companies that switch the better chance the ammo companies will catch up.

Unfortunately they will keep the loadings down to be safe in the SAMII chambers with 10 inch twist. What we can hope for is something in addition for the SPCII/DMR and 11 inch twist. Maybe with a disclaimer such as SSA's Tactical Load.

The downloading has occured in other calibers. I know that the 30-06 could be loaded hotter for the new guns with better steel but all commercial loads are kept down to work with the older guns such as the M1 and early Springfields.

I would say you are correct with that, the good thing is we know we can load up to get an extra 200fps if we want it and any load the mil wants will not blow primers with the new barrel specs.

45-70 suffers the same factory ammo issues - the makers want to load to the lowest possibility (Trapdoors). However, that hasn't stopped Buffalo Bore and Garrett and others from selling shoulder dislocation therapy, with a disclaimer to keep the Trapdoors at home when you go for treatment. Hopefully SSA and others will [continue to] do the same. Load the hotter ammo and just post a lawyer-appeasing warning on the box or whatever.

Companies do the same thing with 556 and 223 ammo... it would be easy for the companies to load two... one for normal and one for the real guns...

Look at hornandy, they could load their TAP ammo to the improved specs like they do for the 556 and load the normal Vmax bullets to the regular... right now they have the same load in two different boxes.

I am saying I think the companies will see that there is a market for the improved loading and come out with it... if they dont then SSA and others will have to pick up the slack.

I ordered my next 6.8 upper from CMMG. My next project is with the 18" SPR Mid-Length gas system and Rifle-Length sight radius (Model# M18M). According to a timeline thread on another website, it will probably be awhile. Patiently waiting 8)

That's what I like about CMMG. They have a great variety to choose from.
