    Storage of loose match ammo

    I load 223 with 77 grain bullets. I put 223 in strippers then into cardboards then into bandoliers. I can get 1,200 into a fat 50. Its a tight fit. If I put 100 rounds of 223 into a quart ziplock bags, I can maybe 1,500 into a fat 50. Its good exercise moving those around. I store 308 and...

    Another chambering issue

    Thoughts ... :) So far you don't know which reloading step is causing the issue. Do the following chamber checks with a stripped bolt - that is, remove shroud/firing pin assembly and ejector pin. Can you reliably chamber ... 1. ... a piece of brass fired in your weapon? - if yes, you have...

    What’s the science behind loose primer pockets?

    Thanks for the images. I hijacked one of them and I will use it to explain my question. okay, the firing pin just ignited the primer, the powder is now in the form of a gas, it is very hot so the pressure is high. The gas atoms are pushing against the walls of the brass. For engineering...

    What’s the science behind loose primer pockets?

    I don't understand the dynamics here. I accept that the barrel/chamber gets larger from pressure and that the brass is transmitting the pressure from the inside of the case to the steel. The powder makes 50k PSI, forces the brass against the chamber walls, the steel deforms elastically and the...

    300 PRC Die Question

    Consider doing sizing on a Dillon. I have a 550B. In the past, I set up a toolhead with a full length 308 button die and a mandrel. I could full-length size and deprime, re-prime and mandrel for each pull of the handle. With proper lube, precision was adequate. About the mandrel: the full...

    300 PRC Die Question

    I use the Wilson full length die with button to ID .303, mandrel to ID .305, and seat with Wilson seater. I anneal every time so neck tension is very consistent.

    Rifle Scopes Optic Failures

    Leupold 36x - had two of them, each worked for about 18 months then had to be sent in. Turnaround under a month, came back as good as new, very good service. Kahles 6x24, used, bought from the Hide, illumination didn't work. Sent in, fixed. Took about 2 months. Kahles 5x25, used, bought from...

    Someone please tell me how this is even possible.

    Seems to me I read about different ways or aspects that a bullet could follow as it went down range. Perfect is when the bullet is spinning around the long axis of the bullet and that log axis exactly matches the computed ballistic curve - minimum drag, easy-to-compute flight path. When...

    Mistakes when reloading

    While loading 300 win mag and 220 grain SMKs using a balance beam scale, I put in 10 grains too much powder. I think it was 82 grains of H1000 instead of 72 grains - compressed charge. Solution: buy a decent digital scale with calibration weights. This was about 30 years ago. I still have...

    Expanding Dies / Mandrells

    I use the 21st Century 0.306 mandrel in their floating mandrel holder thingy. I anneal after every firing. Full length size with a Redding type-S so that neck ID is about 0.303. Using graphite for lube, run each case over the 0.306 mandrel and I get 0.305 neck ID. A 0.306 gauge pin won't...

    Swaging start ups

    About 20 years ago, I made 6mm benchrest bullets for a while - 68 grain, .2435, flat base, I seem to recall 7 ogive. What do you need: three dies - squirt die to make cores of a uniform size and weight, core seater die to seat the cores in the jacket, and a point up die to form the pointy...

    Can't stop breaking sizing dies !

    See attached SAAMI cartridge and chamber print. In your drawing, you said that your fired brass base diameter was 14,96 to 15,0x. In the SAAMI print, the max base diameter is 14,845. The base of your brass is at least 0,1150 mm (0.004 inches) oversize [(14,96 - 14,845)/25.4]. You said that...

    What caused this primer failure?

    You can pull it out or push it out. If it was teotwawki, I would put the bolt between two hardwood blocks, put it into my drill press, drill a small hole into the ejector (think scope base screw), thread the hole, run a screw into the threaded hole, and pull it out. If the world has not...

    Best way to do a neck tension test ... with the fewest supplies

    You only need 3 or 4 pin gauges for each caliber. For example, assume you are sizing for 308. You don't need a 308 gauge, you have bullets that are 308. You probably don't need a 307, you should be able to use your fingers to push a bullet into that diameter. You probably want a 306, 305 and...

    Anyone anneal this fast?

    My apologies. I watched your video a couple of times and I thought I saw the first-torch inner blue cone hitting and wrapping around the neck - not much hitting, not much wrapping around, but a little. When I had mine set that way, the necks did not get hot enough to soften. When I arranged...

    Bullets coming apart downrange - did bad reloading cause this?

    Thanks to everyone for addressing the question. I did not know the answer. When I made bullets, I bought J4 jackets in small tubs. As manufactured, jackets are shaped like a tall straight-wall drinking glass. The jacket wall is tapered from the base to the top edge. I assumed that the...

    Anyone anneal this fast?

    I use a "Vertex bench source". I had some new Lapua brass and the necks were too hard. I tried annealing with the inner blue cone wrapping around the neck and shoulder. Even with the longest dwell time, they were not getting softer. I suggest that you Google "where is the hottest part of a...

    Bullets coming apart downrange - did bad reloading cause this?

    About 286,000 rpm - that seems like a lot. Here is my math -- 12 inches per foot divided by 7 inches per rotation = 1.71 rotations per foot. 1.71 times 2783 feet per second = 4,770 rotations per second. 4,770 times 60 seconds per minute = 286,251 rotations per minute. For comparison, I...

    Concentricity gauge

    Since I don't see that, I'm curious. How do you seat bullets? Are you using factory bullets or custom bullets?

    What happens if you anneal the same case twice?

    Should we anneal the powder and primers too?
