    New 6mm Advanced Rifle Cartridge

    FWIW, when testing my 6ARC gasser I ran it sans brake and then with the VG6 6.5 GAMMA brake and there was a significant difference. Sans the brake it jumped around alot on the bench. With the brake, the spotter dot on target remained in the view during the recoil and settled back on POI at end...

    New 6mm Advanced Rifle Cartridge

    FWIW, I'd suggest you query Craddock on what buffer/spring combination he would recommend to use with his product. I'm sure he has sufficient data feedback to provide some solid recommendations. Keep in mind, he knows the port size so he knows what would work the best, suppressed and...

    Brownells over restricting

    ....can't blame Brownell's for following the new/recent laws that have been passed that affect their ability to remain in business. If you feel the need to blame, then blame the politicians that supported passage then go further back and blame the voters that elected those politicians, but the...

    6 Arc barrels

    Caveats: Powder= LVR, brass= virgin Starline 6.5 Grendel converted, primer=CCI 400, CBTO/COAL= 1.655/2.167, barrel= 18" Ballistic Advantage, RLGS. This was pressure testing ONLY. The highest load shown is under Hornady's published MAX. No pressure signs or behavior was noted. These were...

    BCG hitting back of receiver and buffer tube

    ...it's the BCG that is the problem. rpoL98's post above shows the cause, the sharp 90* edges of that rea portion portion of the BCG that the gas key is mounted to, which is also shown in the OP's 3rd post with the BCG at the entrance point to the RE & buffer tube. ...not knowing how many...

    Low Profile Adjustable Gas Block Options?

    ...my personal preference is SLR, been using them since the first versions came out. Use them on 300BLK(10.1" / 16"), .223/556 (16"), 6ARC (18") & .308/762 (16"). Depending on the barrel length and gas system type, you can match the handguard length to the gas system so the adjustment screw...

    Who Makes Thermal Fit Stripped Uppers?

    ....just my personal experience, YMMV... ...back when stripped uppers were going for cheap in 3-paks, I picked up a couple "just bcuz". Whenever I bought barrels, I would test fit them in the uppers until I found the tightest fit and use that upper/barrel combo for that particular build. I'd...

    VLD Micrometer Seating Die?

    ...the complete seating die can be bought separately, Brownell's has a large selection of brands available. ...if you have multiple calibers to load for and cost concerns, might want to look at the Frankford Arsenal kit...

    VLD Micrometer Seating Die?

    ..what dies are you currently using? Check if the brand you currently have offers just the micrometer top. My Hornady micrometer adjuster came with the VLD stem that is for the A-MAX, ELD-M, ELD-X, CX series of bullets in 6MM/.243 caliber. I've used it with Berger VLD Target, Berger Classic...

    Ballistic Advantage barrel users?

    ...I remember stevieb92's chronicling his 6.5CM build, alot of good info in that thread. The projectiles he used are "secant" profiles, indicative that once one finds the jump/charge combination that worked with the barrel an accurate load can be found... ..... AFAIK, Ballistic Advantage...

    Ballistic Advantage barrel users?

    ...FWIW, I have BA barrels in 300BLK, 556/.223, .308Win & 6ARC, all AR platforms. I have found tangent & "hybrid" bullets more forgiving of jump and easier to find a tighter shooting load than with the secant style bullets. The bullet you referenced is a secant style. It is possible to...

    OAL gauge Vs. Factory ammo

    ...this may help the OP... As shown, various bullet types and brands but have different Cartridge Overall Length (COAL). A closer look and you can see the ogive of each is at approximately the same point (blue line), which is the Cartridge Base To Ogive (CBTO). Although the bullet style and...
