    JP LRP-07 gas adjustment question.

    Each rifle is going to be different, Just close the gas block all the way and start with one half turn open and go from there.

    308 Tack Driver Gas Gun

    The LaRue Xtraxn chamber blows the case out so wide that you can't resize the brass in a standard FL it has to be modified and the neck reamed out to .332, If you try to resize the brass in a standard FL die The case will just get stuck and you'll end up ripping the case head off trying to...

    308 Tack Driver Gas Gun

    I honestly didn't even notice that you were specifically talking about the HK91. I think we have been arguing about two different points and two different rifles and this ones on me. No I have not tried to reload for the HK91/PSG1/MSG90 was only using it as a comparison because of the...

    308 Tack Driver Gas Gun

    Are you absolutely sure the ones you borrowed or owned had Xtraxn???? Yes I'm speaking from experience unfortunately. I'm currently dealing with the issue, That's why I'm having a custom barrel spun up right now as we speak. You can't reload for the LaRue .308 rifles without having custom dies...

    To the OP, Just Google "Reloading larue xtraxn chamber".... And you'll see for yourself, there are countless pages on multiple forums with the same complaint. And bottom line is you WON'T see this issue with JP, GAP, Wilson, KAC, LMT, Seekins and many others

    308 Tack Driver Gas Gun

    I am currently reloading for the LaRue .308 with Xtraxn Barrel. I've used Redding, RCBS and Hornady FL Sizing all of which will not work reliably without damaging the cases or ripping the case heads off. Are you saying you're currently using a standard Forster FL die without any modifications??

    The only way the Forster FL die will work consistently is if you have them ream the neck out to .332 from .327.... Ask me how I know!?

    I can't vouch for the PredatAR and it's slim barrel, but the Heavier barrels seem to do well with FGMM or Blackhills. I actually shoot my guns so paying $27-$30 a box for match .308 is fucking ridiculous. Call LaRue and ask them how they recommend reloading for your new PredatAR.

    For the 16" no, just about perfect for the 16.5" rifle length gas Craddock offers. And if you wanted to change things up with a +1 for a 20" 6.5CM you have that option. The +2 still looks like shit on anything under 15"

    Yeah you did it backwards, but shit happens and it's how you learn.

    Who did the barrel work for you? I'm guessing you didn't heat the receiver up before you installed the barrel?
