    How do you all feel about this chamber job?

    The pics in the OP show the steel is folded over on each side of the lands. Eventually those pieces are going to shear off and will get sent down the barrel. Hopefully it happens when a brush or patch is being used and not while shooting. I don't care who made the barrel. If it was mine it...

    Rifle crown condition

    If you were close I could have re cut the crown while you wait. Or have you do it for experience. I like to take off about 1/2" to make sure the rifling is good. What does the rest of the barrel look like? It just looks like someone had a can or a break on it and never cleaned it. They will pit...

    Customer Accuracy Expectations

    I hate to tell some people this but I have to. Just because your gun shoots a 0.4" group at 50 yds does NOT mean it will shoot a 0.8" group at 100yds. I wish people would STOP saying this. I have a center fire that shoots consistent 5 rd groups of 0.25"at 100yds. But it has NEVER shot a 0.5"...

    Springfield 2020 barrel

    If you are having accuracy issues, check to see if the rounds are getting shaved when feeding. A friend has one and shot BAD!!!!!! So I went out with him one day and was watching him shoot. I could not see him making any bad issues when shooting. As I was standing there talking to him I looked...

    Customer Accuracy Expectations

    A full custom purpose built gun...... Most everyone seems to be using factory made guns and just replacing parts as their custom. No one here has ever showed a real benchrest rimfire gun and what they do compared to a put together gun. So are you building a benchrest or a NRL type? A pure br...

    AR-10 is chewing up my brass

    The reason FC brass was soft was from a cost cutting bean counter. The brass head is not struck one last time to harden it. So one less operation in the loading sequence can save a lot of money or increased production. I got this info from the head ballistician at Ruger. My guess is Hornady...

    AR-10 is chewing up my brass

    If you get the high pressure bolt make sure to get the firing pin to match.

    AR-10 is chewing up my brass

    Hornady brass I find at the range always looks like this out of a AR10. The stuff is crap.

    AR-10 is chewing up my brass

    just because it throws the brass at 3-4 does not mean it is gassed properly. Turn down the gass and get a heavier buffer. But you may not be able to make the brass look better. AR10's are hard on brass

    AAC ammo grenading rifles

    These are splitting because of the case drawing operation had a problem. The brass gets thin on one side and this happens. It happens to EVERY brand of ammo. Some it just happens more often. Most people don't reload and don't pick up their brass so they would never know about it

    Jarvis cz457 barrel

    Looking to replace the barrel on my cz. Looking at some of the cheaper barrels. I don't see a whole lot about these barrels. All I can find is barrels they did on a rem 597. I don't care about the expensive barrels. Not going to happen. Already into this for more than I wanted to be. Anyone?

    CZ 457

    the cz rifles come pillar bedded already. Some are plastic but others are aluminum. Mine are aluminum

    What did you do in the reloading room today?

    Sized and swaged a 5 gal bucket of 9mm. My arm is killing me.
