    Acceptable Elevation Tracking tolerance

    If the reticle agrees with the turrets, you're likely at something a bit further than 100 yards.

    Acceptable Elevation Tracking tolerance

    I've done that test with SWFA, Leopold VXIII, Vortex Viper PST, and Vortex Razor. I only do 10 mils, and have never been off more than my ability to resolve the centers of the groups, maybe 1/2" between the two. There was plenty of resolution to figure out if the Leopold was .25" or .25 moa...

    Sidearms & Scatterguns SIRT Trainer Pistol

    I'm kind of surprised nobody is using these. I've had one for several years and it's an extremely effective training too. Potential training scars are - Looking through the sights for the laser becoming habitual - Believing you're as fast with recoil as without it - If you're still riding the...

    Acceptable case wall thickness variation after neck turning

    Good job, but you might be over doing it. I look to cut 60-80% of the neck. Anything that gets trimmed more or less than that gets tossed. Anything that shows a lot of variation along the neck gets tossed. I don't think these things help uniform the neck tension anymore, but the necks give...

    Under sized 308 brass

    Depends how many times they've been fired like that. If they haven't been fired, the 2 fire forming techniques that can be used to lengthen them are loading the bullet out to hit the lands and expanding the neck up before sizing it back down to create a new shoulder. There are no bullet fire...

    Looking to re-chamber... Short Action Remington 700 - What to do?

    I was wishing out loud that I could get the Sierras for the same price as the Hornadys and a little chagrined that I'm going to get much better ballistic performance for a lower per round cost. The 2 bullets being compared are for such different purposes they might as well be different...

    Looking to re-chamber... Short Action Remington 700 - What to do?

    Depends how bad you want to hit it, what you want to happen when it does, and how big the target is. I'm at ~1500', 28.5 inches of barometric pressure, and my calculator has it going transonic (1340 fps) between 900 and 950 yards for muzzle velocities between 2850 and 2900 fps. At 1000 yards...

    Looking to re-chamber... Short Action Remington 700 - What to do?

    If you'd like to keep a lot of the low cost attributes of the 223, you might look at rebarreling with a 1:7 or 1:8 twist and throat it to take the 80 grain Hornady Amax's loaded out to 2.5" OAL. It's a whole new 223. There are better bullets, but those Amax's are cheap. It'll give a little...

    77 SMK trial loads

    Which brass you use will matter. For PMC holding 30.5 grains of water after sizing. The gun is a Mossberg MVP with a ton of freebore. The bullets won't contact the rifling until 2.400" and they're loaded to 2.260" to fit in the AR magazine. It's a 1:9 barrel and the stability...

    7 WSM and Berger 180 Hybrid help

    The Berger reloading manual gives a starting load of 63.0 and a max of 66.4 grains for H1000 and their 180 grain bullets in the 7wsm.

    Choosing which rifle to build upon

    s Depends on what you call build. If you want to hang a scope on it and go shoot, the odds overwhelmingly favor that Savage outshooting that particular Remington by a wide margin. If you want to rebarrel it yourself in another caliber, you can do that yourself on the Savage without...

    6.5mm 140g berger hybrid seating depth question.

    Litz's book gives 0.689" as the nose length on the Amax The Berger reloading manual gives a nose length of 0.816" for the hybrid and 0.721" for the vld. The bullets are not contacting the rifling at exactly the ogive to bearing surface transition because the rifling diameter is smaller...

    Range Report Which Bryan Litz book to start with?

    I read the books first, starting with Applied Ballistics and bought the DVD on the recommendation of a friend. The DVD is more of a hands on demonstration but some of the comments made some lights go on about things I'd read in the books. I suggest starting with the DVD and then going to...

    Help with Shoulder Bumping

    I loaded with the braille method for a long time. Since starting to actually measure the headspace I've found one die in my set that would bump the shoulder back 0.025" below SAAMI minimum and 4 that wouldn't bump enough. One needed 0.020 turned off it before it would bump at all. Most of...

    Gunsmithing New 6.5 Creedmoor Won't Shoot New Factory Hornady Match Ammo 140 gr. Amax

    Will a case with a pulled bullet chamber and pop the primer? Accuracy Systems does have options to get factory Hornady ammo to chamber in a 6.5 Hornady Creedmoor barrel. With the bullet the round was designed for no less. One would be a throating reamer, the other would be a correctly...

    match rifle ammo: dillon 550b vs 650

    I set up each of the tool heads with a Lee universal decapping die. Either to remove the primer or make sure nothing from the tumbler is in the primer pocket or flash hole. I set up that die to stop the ram short. This keeps the press from springing and keeps everything length involved much...

    match rifle ammo: dillon 550b vs 650

    I loaded with a 450 for 20 years, then that press with the 550 upgrades for a few more before buying the 650. For rifle ammo, the principle advantage of the 650 is the case feeder will work with rifle cases. This can make you pretty cavalier about how many times you run brass through the...

    New Tipped Matchking "TMK" loads from BHA??

    Sierra did well in the Litz paper on advertised ballistic coefficients for the Air Force Academy. Hornady also did well. He uses them in his book to talk about velocity dependent ballistic coefficients and presents them in a positive light. The drawings in the back of the book make it clear...

    Nato Brass Case Capacity

    1 ml of water weighs 1 gram, 15.4 grains. This sorting goes pretty quickly with a digital scale. Brass has a specific gravity of 8, meaning it takes 8 grains of brass to displace 1 grain of water. My experience has been the relationship between case internal volume and case weight is breaking...

    Gunsmithing Remington factory stocks

    The plain vanilla Remington plastic stock on the SPS SS line is pretty bad. Flimsy, no pillars for the action screws, and lots of contact with the barrel. I bought a Stevens 200 as a donor gun for another project and was surprised that it's plastic stock did have pillars and the barrel was...
