    Concentricity gauge

    You have targets for that, a gauge is not helpful. Just for fun, check this page. It is the national benchrest shooters association (NBRSA) group size hall of fame. Notice the top guy, Tony Boyer with 176 points. Notice number 2, WAYNE CAMPBELL, 59 points. Boyer has just under three times...

    Sizing down brass

    SAAMI says the necks on your 30-caliber brass and 7mm SAUM brass should be no more than 18 thou thick. 30 caliber bullet diameter is .308, max diameter for the round is .344, .344-.308=.036/2=.018. 7mm bullet diameter is .284, max neck diameter for the round is .320, .320-.284=.036/2=.018...

    Small, easy portable and stowable reloading solutions.

    Basic benchrest kit: In addition to the press, add Wilson neck die and seater. Buy a powder thrower and stand. Buy a priming tool. Use fine-grained powder. If you have the settings for your powder measure, you don't need a scale. Add a pound of powder, brass, and 100 primers, it will all...

    how much does a powder trickler help?

    I have a good powder thrower. I used it with a Dandy and a quality load cell scale for a while. Process: pick up the scale pan, throw 95% of the final charge, set the pan on the scale, trickle to the right number, throw the charge, move the funnel, and repeat. I set the Dandy next to the...

    how much does a powder trickler help?

    "Help" is relative. What kind of shooting do you load for? What sort of scale do you have? How many digits to the right of the decimal point? Do you need to go a little faster or a lot faster? How much accuracy do you want and can afford? My original scale was a Ohous 1010 - still have it...

    300PRC +P Load development

    I stopped rock climbing a few years before cams hit the market. I was using Chouinard nuts - I still have some and some blades and bongs, some of those postage stamp pitons, and similar stuff. I was more into ice, rigid boots and crampons, and Salawa ice screws. I am very familiar with...

    300PRC +P Load development

    I do not understand how this will work. I looked up the yield strength of 316 stainless steel - about 30,000 PSI and cartridge brass - about 75 MPa (megapascals) or about 10,000 PSI. Given the yield strength numbers, the steel will accept about 3 times more pressure before yielding than brass...

    I'm going to re do my last batch but, before I begin ...[UPDATE]

    This forum is for people who reload. Some are just starting. Some (like me) have been doing it for longer - I started to reload in 1970. This forum is not divided into beginner and experienced groups - both are present and both are welcome. You choose to make comments directed to those who...

    I'm going to re do my last batch but, before I begin ...[UPDATE]

    Hi Sheldon, We may disagree on torque. I am not seating the die against the shellholder. I have the lock ring fixed in place. I torque using a hex-sided lock ring. Torque is to insure that the distance between the shellholder base (where the brass pushes against) and the .420 line in the...

    I'm going to re do my last batch but, before I begin ...[UPDATE]

    Some additional detail on the Hornady comparator devices. I am working with a 300 PRC with a mostly SAAMI chamber - throat is 0.015 longer than SAAMI. The datum diameter is .420 so I attached the .420 body to my caliper and checked caliper zero. 2.003. According to the SAAMI print, the case...

    300 PRC

    I'm getting halfway decent groups (sub-half MOA) with 72 grains of 7828 and 215M primers and Lapua brass. Has anyone else tried a combination like that?

    My first reloading attempt was a failure, what now?

    Do not throw them away. There is a lot of value there and it isn't just the cost of components. I worked up a load for my 308, I thought it was great. I made about 1,000 rounds of it. Time passed and I discovered that load wasn't as good as it should be. I disassembled it all using this...

    300PRC +P Load development

    I'm just a knothead with a computer but I thought I would run some of your computations through my stuff. I am generally suspicious of internal ballistic tools however, I downloaded the GordonsReloadingTool and it has been working for me. I ran a prediction using the specs from your post...

    What type of malfunction is this - when bullet doesnt eject

    You need a flashlight if the load factor is small - case only a third full or some such. If you use a large load factor (say 80-90%) , it is easy to see the powder level in the case since it is nearly up to the neck. A decent overhead light will do. Another advantage of large load factor -...

    Protecting a map question ?

    Fewer buttons to press, you can see the whole scene at the same time, they float (mostly), there are no button clicks to drop a waypoint, you can guess at a distance with a glance and get a good estimation with a simple ruler, they emit no energy - neither light nor radio, it is easier to...

    Ammo storage & transportation

    For 5.56, three techniques: 100 5.56 rounds into 1-quart freezer bags. I can get more than 1,200 rounds into a fat-50. 1,200 rounds in a can is heavy. 5.56 into 10-round strippers, cardboard sleeves, bandoliers and a spoon - 1,200 rounds in a fat-50. go-can: loaded mags. For precision...

    Self sustained multiday matches?

    This is a blast. Theme is the movie Red Dawn. There are usually 8 shooting stages and a 5k land nav ruck in the woods carrying 25 to 45 pounds, you get your next checkpoint from your current one. Land nav usually takes 2 to 3 hours, you have to run to do it in 2. It is much better to be on a...

    "Match Grade"

    "Match grade" has a meaning - it means that whatever "it" is will cost more money.

    Brass Resizing Dillema

    What safety risk do you think exists in this case? How do you think the brass will fail and how might you or someone else be injured by that failure? I don't think that your 10 cases are unsafe. If that was my brass I would shoot them or toss them depending on how much brass I had and my...
