    Recently, I have started shaping the firing pin tip to kind of a cone with a radius. This for larger pins (like the post 64 Model 70). I started doing this in an attempt to prevent blanking without...

    The thing is, since there is very little torque applied when tightening the barrel on, there is no need for a lot of shoulder. Still, I agree there should be a reasonable amount of shoulder contact. ...

    If the shoulder has deformed, the use of a shim may be appropriate. If it is the threads which have loosened, the technique is to set up the threads by using a radiused punch to move the threads...

    Sounds like a 30 caliber based on the 35 Remington case if your diameter given is at the base of the case. If it is at the shoulder, the case is likely based on 308 brass. Regards, Bill.

    I have always turned and threaded the tenon then chambered. When I first started doing barrel work (1977), turned and threaded the barrel between centers then set up in the steady rest or the four...

    The claims of high velocities coupled with superb accuracy and extended barrel life, when taken all together, are known by the technical term, " A load of BS". Regards, Bill.

    Jackie,
    It's interesting to look at the original requirements for "F" class shooting (as written by the founder, George Farquharson) and compare them to what they have become. The original...

    While there can be no doubt that straightening or bending a barrel will induce stresses, there is some question as to just what the effect may be. Keep in mind, unless the barrel is stress relieved...

    Common practice used to involve using a string or wire stretched in front of a window. Looking through the bore at this would produce a definite shadow line which, if curved or broken, indicated a...

    The reason for working with the 30/30, or any other old cartridge, should be immediately obvious: because you can and because it's fun. I built my own 30/30 on a modified Ruger 77 (initially built a...

    When I started out, we bought all our barrels as 1 1/4 blanks and contoured them to whatever (barrels were mostly from Shilen, Hart, and Douglas). Even now, I frequently re-contour to acheive proper...

    Increasing freebore will reduce pressure and the velocity will also drop right along with the pressure. Load back to the same pressure and you will find the velocity will also be the same or very...

    I have used 4350 and 4831 sc with 80 grain bullets with good success. I think the 4831 is too slow for 69's. I just bought a jug of 4451 and have high hopes for it. Regards, Bill.

    As much as I like good, old stuff, I believe I would pass as well unless condition is exceptional and you are attracted to the machine. For BR barrels, the hole is too small. Regards, Bill.

    Though I have had some success with Varget, I have always gotten better accuracy out of 4895 with 155 grain bullets and 4320 with 175's.. Regards, Bill

    The only reason for a close thread fit is so, when the barrel is removed, the guy thinks to himself "Nice fit". Same thing for a nice, smooth cut and nicely radiused corner at the shoulder. "Nice...

    I don't make any claims that I am always right but I have a done a lot of chambering over the last forty years. I have used flushing systems and liked it fine but I am perfectly happy blowing out the...

    Not mis-remembering but perhaps misunderstanding. The Remington is a sealer. In the event of a castastrophic case failure, the bolt nose is supposed to expand to seal in the counterbore and this is...

    I dislike bipods on general principal so prefer to not use one. I can shoot with a sling and sandbag support or I can use a pedestal rest with two feet (BI-pod) which is loosely attached to the rifle...

    Yes, .002 is the normal allowance for crush. The use of the dial gauge to verify clearance is certainly just fine.
    For myself, I figure clearance is clearance. On match rifles I'm happy with .005,...

    I think I would have to tape a five dollar bill to it to get someone to steal it. I guess I wasn't clear enough when I ordered it. Regards, Bill

    I suppose it could but it is easy to measure the Remington and simply cut to the measured depth plus .005". On a coned breech, I cut the cone a bit shallow then I put the bolt in the action in the...
