    Annealing machine.........

    I keep hearing in the videos that they changed the amp to a touch screen so it’s easier to replace, does that mean the screen or the buttons on the gen 2 breaks often? At some point they will stop making parts for the gen 2 as it costs too much to make parts for older models like any other mfgs.

    MoneyPitArms Matrix Thumb Wheel ball and spring

    Take the cheek riser off and you see a set screw. Remove that set screw and turn the chassis over to let the spring fall out. Put a while towel or shirt down so you can see the spring when it falls out. Slide the wheel out and the detent ball will drop out with it. To replace it put the wheel in...

    Am I being an idiot - Why am I getting pressure signs here?

    After Seems to be the carbon build up if after 50 rounds the pressure appears. Scope the chamber after 50 rounds to see if there is significant carbon build up in the throat.

    Rough Rust-like finish inside alpha brass necks

    Another option is to dip the base of the bullet in graphite and give a few swirls. There should be enough graphite sticking to the bullet to allow for easy seating.

    Another suggestion remove and reinstall the barrel, make sure you snap it on to engage the threads.

    Am I being an idiot - Why am I getting pressure signs here?

    1. Clean that barrel to bare metal with thorroclean, JB worst case Iosso. Scope it and make sure all the black carbon is gone from the throat area. Next run a patch with alcohol through the chamber and barrel then go shoot. 2. Try shooting with the ejector spring removed but the ejector in...

    terminus action firing pin and spring complete disassembly?

    I don't think you can mess up the firing pin travel. Its one screw between the shroud and the firing pin, line up holes and screw it in. Its that simple. Maybe he wants to use a lighter firing pin spring.

    Terminus Action Review / Observations

    If you think its the scope and rings remove it and see how the brass ejects. Change the ejector spring to a lighter spring. Joel has to be one of the best when it comes to CS.

    6mm BR

    I make the necks glow red and the annealing line is below the shoulder, what I found is that if you don't get it red when you bump the shoulder and size the neck there is spring back. I swear its more of an art than a science.

    6mm BR

    I might have missed it but what die are you using? Could it be the brass has grown so much and the die is not sizing the body down enough which is causing the brass to swell up and not contract which could be causing the increase in pressure therefore increasing velocity? Could there have been...
