    Disposing of Live Primers

    Not all primers are correctly seated in casings. How does one load a deformed one into an unmodified casing? The only other option is to burn the primers - carefully. Primers in a fire have the ability to penetrate thin layers of aluminum foil. A steel can (such as a 10 or 12 ounce canned...

    Disposing of Live Primers

    This is a topic which brings about a lot of discussion on how to do it. For the record, the following methods DO NOT WORK: Soaking the primer in oil, and; Soaking the primer in water. Chemical neutralization of the priming compound is the only reliable way to neutralize a primer. From the...

    was creighton audette a br shooter ?

    If you can wait for an answer.... I know Middleton Tompkins and Creighton were friends. Seem to recall that Mid said he had fired BR matches on occasion (and won a few), not sure if Creighton did. Will try to remember to ask Mid in early February when I see him next. Most likely, Winchester...

    Barrel life

    Barrel erosion. Think about it - powder burns at over 5000 F, despite the burn lasting for .8 microseconds (best guess) or so. As the gas expands, temperature drops. Still, the first 3 inches of the barrel gets hit by a wall of hot, reactive gas. Carbide and nitride gasses are the worst at...

    What brand of stocks are these??

    Top stock is wood, not fiberglass. It is similar to that found on an 40x .22 rifle, though the bottom of the stock appears different (not inletted for the drop-plate magazine box.) The long oval in the foreend is for an older style handstop setup (see...

    Mark 4 LRT 16 power fixed ( TMR Reticle)

    Plusses: Overbuilt. Originally built for .50 BMG shooting (SEAL Team contract). One remark often made about these units is the can be used to drive nails - Leupold may actually have done so in an advertising campaign; Large elevation range. Lots of room to get rifle zeroed, leaves windage...

    Cardboard backing

    Experience from other shooting sports says that Corplast is the last material you want for competitive shooting sports. While it's light and durable, the "waterproof" part means many water-based glues do not adhere to it. Additionally, after long term use, the center bows as the plastic...

    What is the appeal of F Class?

    While there are dedicated F-Class matches, most events are fired alongside NRA Prone Matches. Courses of fire are typically identical to those fired by prone shooters. A list of upcoming NRA Highpower matches can be found at https://www.ssusa.org/coming-events/. Hope this helps.

    What is the appeal of F Class?

    Your questions can be answered (in writing) by looking at the NRA Highpower rulebook at http://rulebooks.nra.org/documents/pdf/compete/RuleBooks/HPR/hpr-book.pdf . NOTE: While there is a separate section for F-Class in the rulebook, parts of the ENTIRE rulebook still apply to F-Class. Best...

    Old used barrels

    Al, Back in the 1950s, the US Navy had piles of surplus material, and a serious lack of funds for things like rebar. For at least one project in San Diego, surplus 1903 rifles (barreled actions) were used to provide support for the foundations. Most of the structures were still standing as of...

    How did they make barrels

    Or, a thin metal liner was wrapped in leather strips. Apparently, rate of fire was a real problem with guns built in this manner.... https://en.wikipedia.org/wiki/Leather_cannon Actually, the better 18th and 19th century cannon were made of cast bronze. Sometimes the "bore" started as a...
