Who actually uses the SAAMI reamer on AR barrels?

[LRRPF52]

If this group is okay with non-SAAMI chambers I would expect to see more referrals to new people looking to build to more cost effective options. Instead because there are no sub $400 saami options people seem to be guided to $700-$800 barrels. Thats great if you guys have the passion/dedication to drop the coin on that steel. I am a professional brewer at the moment, means average labor wages in manufacturing. So without means I am trying to build a decent rifle but sensibly spending. I may be able to pay $1500 between the barrel and upper but I woumwould rather save the extra for other things.

There seems to be a lot of self contradictory statements made here. That is unless a compound throat is in fact magic. Using common sense and reasoning every chamber type has its preferred rounds. That includes the lauded compound throat so it seems. I am just pointing out the one sidedness for the SAAMI and how loading for your chamber still applies. Unless like i said, the magic makes it special. We use magic water at work, so its possible here too.

This thread title was about who makes SAAMI-chambered barrels. People asked about the chamber differences, and what contributes to accuracy. A lot of people have had variant chambers and have been members on the forum dating back to the old forum. I have not seen any sense of elitism. I'm also unfamiliar with the $700-$800 barrels you are referring to.

I paid $269 for my first AA barrel/bolt combo ordered from Midway in 2009. I didn't know anything about the chamber dimensions, other than it was a 6.5mm based on a more forward shoulder location off the PPC case, which is a renowned benchrest cartridge.

Back then, AA was carefully controlling the licensing of 6.5 Grendel Reamers to barrel makers who were willing to hold a certain standard, since it was a wildcat, and SAAMI certification was still on the horizon.

Bill A. has said himself that he's happy with more people shooting the cartridge, especially so when their rifles will reliably feed factory ammunition. That helps the cartridge in the long run.

I don't know about magic, but the compound throat works as advertised in my guns. When people ask for more economical barrels, I personally refer them to several sources, including barrels with a variant chamber in the sub-$300 range. I even sold a Grendel starter kit here through the site with reloading dies, our reloading handbooks, shell holder, mags, and a Brownell's barrel/bolt combo.

There are people who own .264 LBC barrels that were advertised as 6.5 Grendel. They feed and fire factory ammo just fine. There are others that have had problems. I'm not sure where you're trying to go with this, but there is no exclusionary environment on the forum based on what chamber someone owns. Heck, there are people on the forum that don't even own an AR15 (can't), or don't own a 6.5 Grendel, and are great contributing members.
