Maybe later this summer.

Id be interested in your favorite factory loads, if you care to divulge them..also, who makes a rear-banded carrier? I cannot find them.

Google "Anti-tilt bolt carrier"

How about a slightly different approach?

Black Hills 77's-- just over half an inch (Blue Box). Nosler 69's and 77's, same. Federal GMM deserves its rep too for accuracy. My two most accurate barrels are a Wilson Combat Super Sniper 20" and an Adams Arms Voodoo which surprisingly is a standard Gov't profile barrel.... but wow it shoots!

Almost anything with 77 Sierra Match Kings will hover around or under an inch-- the IMI, the CBC for example. Hornady loads 75 BTHP's thee ways including a "match" version but for me the most accurate has been the 5.56 version (the others are .223 pressure).

Putting "national match" in front of something is akin to putting "tactical" in front of a product name. It doesnt mean shit.

I tend to agree fully. The noted differences on the Young Mfg bcg were a 30% increase in the contact surfaces of the carrier, along with being 1 ounce heavier for dwell time.
"Supposed" to keep bolt in more perfect alignment during lock-up. Thats what THEY say...and why I asked here for expert advice.
After reading and studying this issue for a few weeks now, Ive come to believe that, yes, it PROBABLY makes some difference..but getting a bolt matched up to a barrel will probably achieve as much or greater results, so thats where Im headed right now, pending further incoming info.

I really appreciate that info sir, awesome of you to give it out. Some dudes guard that info like the family jewels!
