  1. 300 BO not locking back

    UPDATE!! I got the 300 running perfectly. Confirmed it was short stroking on the Freedom Munitions 147 and did the same on Barnes 120 grain, but American Eagle 150 grain ran fine with the standard spring. Once I swapped to a lower power spring it ran everything perfectly. Locked back on...
  2. 300 BO not locking back

    Will do! I have to run to Gainesville on Thursday so I'm going to grab a couple boxes while I'm there.
  3. 300 BO not locking back

    No my shooting spot is a few miles into the Chattahoochee national forest on a long dirt road, and my wife has had the truck lately. Haven't been willing to take the company car back in the mud yet. Haha
  4. 300 BO not locking back

    Should be getting my Sandman S in March but I'm hoping to get it running reliably unsuppressed as well.
  5. 300 BO not locking back

    Not that this is necessarily relevant to the weight discussion, but I should have mentioned that it is feeding from a Magpul 300 blackout pmag.
  6. 300 BO not locking back

    Ok that makes a lot of sense! Thanks!
  7. 300 BO not locking back

    Isn't the bolt catch reliant on the mag follower to press it upwards in order to lock the bolt back? Not trying to be argumentative or anything I'm just trying to make sure I understand.
  8. 300 BO not locking back

    Plugged the champer with a spent cartridge, blew air through the muzzle and stuck my pinky up inside the upper to the belled end of the tube. Tons coming out the belled end.
  9. 300 BO not locking back

    There does not appear to be any gas leaking out around the gas block. So that's good news.
  10. 300 BO not locking back

    Just checked the gas tube and air is flowing through it freely and smoothly. Gas key is not loose and air moves freely through it with the bolt forward, but does not when the bolt is pressed back into the carrier. I don't really have any way of measuring the gas port on the barrel or the belled...
  11. 300 BO not locking back

    That's what I would have thought but I read tons of posts on forums of people saying it had helped because their bolt was out running the mag spring and they were getting bolt override. The thing I can't figure out is how to diagnose the difference between short stroking and bolt override...
  12. 300 BO not locking back

    Just shot my 300 BO build for the first time this weekend. It is ejecting rounds to my 3:30, but not very far, I don't think it is under gassed, because I am using a Ballistic Advantage Hansen Barrel (pinned, non adjustable gas block, so it can't be misaligned or tuned too low, pistol length gas...
  13. Pin & Weld Services N Georgia?

    I'd prefer to find something a little closer, but if not I'll hit you up! Thanks!
  14. Pin & Weld Services N Georgia?

    Anyone know somewhere near Forsyth County or north that offers pin and weld services? I'm in Dahlonega so looking for somewhere fairly local to me. Thanks guys!
