    Rookie benchrest value question

    The Warners still make sights - but on a very limited basis. Prices have increased steadily over the years, with the result that they now cost about the same as a middle to middle-high end scope. They used to make two models of sights, with the rarer model being the #2. This model had more...

    Rookie benchrest value question

    FYI, some of the aperture sights appear to be Warner sights, (www.wtc.com - old website, Present site is https://www.warner-tool.com/ .), which are very precise, and also really expensive. Keep this in mind when pricing these rifles.

    Rookie benchrest value question

    Asa non-benchrest shooter, here's my impressions: Photo #1: 3x highpower/long range rifles, and an air rifle. Wood stocked one with the long barrel is a prone-only rifle, possibly a Palma rifle (if chambered in .308 Winchester); Photo #2: 5x rifles for position shooting (I hesitate to say...

    Ideal Twist AR15

    Not every chamber for 80s is a Colt or a Wylde, there are others. I stand by my statement, there IS at least ONE magazine designed to load and feed 80 grain loads.

    Ideal Twist AR15

    All, Rifling twist and bullet weight are tied closely to the evolution of the AR-15 and M-16 rifles. I am quoting from Mike's post, because he seems to list so many. IIRC, plastic tipped 55s didn't become popular until the 1990s. The 1-14" twist disappeared on the AR-15 in the late...

    M1a Issue

    What LOAD w/LC brass? The answer to this question matters, big difference between the 175 grain load, and the 147. Rifle should cycle w/ the 147, it may or may not with the 175. You are aware that LC changed the powder in the 175 grain load? A year or two after Winchester took over management...

    M1a Issue

    Lngrng, 1 key point not mentioned in your post. What load are you using? An M1A is VERY preferential in what it shoots. Designed for a 147 grain bullet Fired around 2650 FPS, the gas system is limited to sub-180 grain bullets at velocities below 2600 FPS. Combined with the requirement to...

    Sako vixen.?

    Which Sierra 55 grainer? Big difference between a softpoint flatbase and a FMJBT.. The FMJBT needs more twist, due to the length of the boattail. Thisis why the US Army changed rifling twist on the M-16 from 1-14" to 1-12" before fielding the rifle. Cold weather tests (Alaskan winter) showed...

    prvi priming problem

    No, and no. An AR-10 can slamfire, the initial reviews of the SR-25 rifle (circa late 1993) noted the gun would occasionally fire w/o actuation of the trigger, supposed cause was use of Federal primers in the tested ammo (Federal Gold Medal Match). The first AR-10s from Armalite would also do...

    222 Rem best twist

    Tracer bullets NEVER fly the same as a ball round. Why? The ball round keeps most of its mass in flight, the tracer's is affected by the tracer's burn. For starters, the bullet leaves the barrel with mass, and as it flies dowrange, loses mass as the tracer compound burns. It also flies...

    222 Rem best twist

    The M-249 was originally built in Belgum and used Belgian designed ammo. The added length of the tracer added burn time, as existing 5.56 mm bullets did not have sufficient capacity for the desired performance. (Provide trace out to 800 yards?) The US adopted the ammo, and redesigned the M-16...

    222 Rem best twist

    Actually, DENSITY of the bullet determines twist rate, not the length. You can get an 80 grain HPBT bullet to stabilize in a .221 Fireball, assuming the twist rate is appropriate. Change bullet composition to say, copper, and you might need more spin to stabilize the projectile. Or, change...

    40x rimfire bolt cleaning.

    AHHHHHH! Breaking your bolt while cleaning it is a bad idea!!!!! :D (KIDDING!) The correct spelling is "Brake Cleaner". I do not see a problem with your process, it is the same as using an aerosol gun cleaner for the same purpose. Just make sure to use a light coating of a light oil (or a...

    Depending on the type of target used, it is legal to use electronic targets for NRA highpower. Let us not forget that F-Class is part of highpower, not an independent discipline.
