    Gunsmithing remington 700 to 300 norma mag

    When I built a 300 NM on a remington I open the threads up to 1 1/8-16. I permanently mount a scope rail and pin both ends with interference fit pins to stiffen the action. --Jerry

    WTB Remington 700 LA LH 308BF Black bolt

    Needs to be in new or near new condition. Long Action, Left Hand, .473 bolt face. PM if you have one or know where one is. If you are a lefty looking to build a nice remington 700 LA, consider putting a PTG bolt in the action and I'll buy your remington bolt.

    Gunsmithing 6XC II go gauge

    As I understand it 6XC II is what we've been using for a while. we moved away from the 22-250 based 6xc a long time ago. Renaming should have happened then. Doing it now has created some confusion--for example there are a lot of 6xc reamers out there not marked 6xc II but they are.

    Gunsmithing Loctite 620

    Heat to 400 deg or so. Loctite's weakness is heat. the temperature needed to release loctite does not affect steel or even anneal brass. Heat with a torch. I'd use MAPP gas. You're going to need a lot of heat for the large parts. heat evenly from 2 or 3 directions. You should smell the...

    Gunsmithing Can you headspacewith a fired case

    When I want to headspace to fired brass, I usually measure the shoulder of the brass and compare it to the headspace gauge, and calculate the final headspace gauge measurement I want for that brass. The goal is generally so the shooter doesn't have to adjust his shoulder bump on his die when...

    Gunsmithing Can you headspacewith a fired case

    To answer your question the way it is asked, yes I can. But if you have to ask, then you probably don't have the talent to do it. It is very easy to resized the case in the chamber without knowing it.

    Gunsmithing Trigger installation

    Not common but not acceptable. low probability, high consequence. Thus worth the trouble to confirm no accidental discharge.

    Gunsmithing the intricacies of threading?

    I installed a muzzle brake today, 1st time since this thread started. Above I posted that I much prefer to have the brake in hand because so many of them don't meet the thread spec they advertise. I don't want to name names of those that I've found to be out of spec. It is a small world...

    Gunsmithing the intricacies of threading?

    If it is a used barrel, the threads could just be dirty. Clean with fine wire brush. If you are using a used muzzle brake, then often the Muzzle brake threads have carbon buildup on them. Make sure your muzzle brake is the same pitch as the threads on the barrel. While threads are somewhat...

    Gunsmithing the intricacies of threading?

    Ok. I'm doing it wrong. I try to make it easy on my customers and don't make them argue with a manufacturer so I won't have to take another pass off the muzzle threads. I don't want to argue. You keep doing it your way and I'll keep doing it mine. --Jerry

    Gunsmithing the intricacies of threading?

    Rube, So if your customer sends you a muzzle brake that isn't per spec do you return it and tell them you can't fit it? --Jerry

    Gunsmithing the intricacies of threading?

    Chad, I'm not sure you were that polite. I have NIST traceable thread gauges older than many of the members here, I'm sure older than your new CNC machinery since CNC wasn't widely used when they were made. I have a drawer full of custom thread gauges that I've made myself for threads I needed...

    Gunsmithing Punches... Good ones?

    Ejector pins are pretty easy if you have the right tools. I remove and reinstall several per week as I bush a lot of firing pins. They are 5/64 nominally. Most roll pins are pretty easy to get out if you have the right punch and are tapping it square. I don't remember the last time I had a...

    Gunsmithing Punches... Good ones?

    All punches will bend if subjected to bending forces. Work on your technique. Choose a short punch to start a tough pin. don't use a long punch until you have it moving.

    Chad, Your gauges won't help me if your threads are perfect and the muzzle brake in .002" under. --Jerry

    Gunsmithing the intricacies of threading?

    Some good information in this thread on how to manage thread class and fit. However, as the OP pointed out. many brakes etc are made in small lots in various shops and often do not meet the thread class that they are advertised as. I always ask to have the brake or muzzle device in hand if...

    Gunsmithing Excessive bolt wear ?

    That bolt has very few rounds on it...probably because nobody can shot a 7 STW more than a few rounds. I'd expect to see significant cratering with moderate of heavier loads. Magnum primers may help.
