    Gunsmithing barrel scopes!

    Re: barrel scopes! My interest would be for the 18" model. A mirror on the end so you're looking 'up' at the lands and grooves would be important, as well. A 90 degree eyepiece on the end would be a nice option, but not a must. Thanks! -Al

    Gunsmithing Bolt face erosion?

    Re: Bolt face erosion? William: Barring excessive pressures (whatever that might be), the biggest single thing you can do to minimize gas leakage is to have as much of the case as possible completely in the chamber. That's why the coned bolt actions with a sliding plate extractor...

    Gunsmithing Bolt face erosion?

    Re: Bolt face erosion? Even though the gas cutting on the b.f. looks bad, it really doesn't hurt anything, functionally. One of the reasons I asked about the cases used was because the primer leakage ring is off center from the firing pin hole. 'Course, that's not unusual anyway...and...

    Gunsmithing Bolt face erosion?

    Re: Bolt face erosion? Did you get any brass with the gun? I've seen this with 6.5X284's that used Winchester 284 brass or Norma 6.5X284 brass in a chamber done with a reamer based on Lapua 6.5X284 brass. The Lapua case is bigger at the back end than either of the others and it doesn't...
