    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.

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

    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...

    Rough Rust-like finish inside alpha brass necks

    It’s the opposite, you still had carbon inside the neck and the mandrel removed the carbon to expose the brass under it.

    Probably meant extractor as the ejectors don’t brake unless it was hammered with the pin. 😂😂

    terminus action firing pin and spring complete disassembly?

    You drill a hole in the block of wood or use a muzzle brake to fit the firing pin in so it doesn't bottom out. Compress the spring till it hits the back of the shroud and start unscrewing. Once the screw is completely removed let the pressure off. To reinstall do the opposite. A long quick clamp...
