    Can I use this powder?

    Some time ago, I watched Skip Otto do that with Vit 133 in 6ppc cases. He was trying to minimize flight time. It sort of worked but it was hard on barrels. I'm not sure how many times he did it. It might have been just once but it seems to me that he did it for a couple national matches. He...

    Can I use this powder?

    Hi guys, 8 pounds of vintage H1000. Metal cap. Note the reddish "rust" around the cap. Good? Or, not good? Smells like acetone, does not smell sour.

    Eric cortina seating depth

    Maybe off-topic, a little. I am out of BR now. Some years ago, I used to watch Mr. Boyer shoot matches - with his funny hat. He did not win by shooting a lot of small groups. At that time, he won because he almost never shot a big group. The man had great aggregate scores. He was the...

    Eric cortina seating depth

    Ever shot a big 3-shot group, then added more shots to it, and the group got smaller? If it starts out small, it might stay small. If it starts out big, move on - unless it was you. That is the value of small 3-shot groups - they help you sort the wheat from the chaff.

    Crimping for rifle accuracy…

    When making 300 grain solids for a 375 H&H, I crimp. Otherwise, not.

    Velocity- Accuracy Relationship Question

    "You then change powders to brand Y but change nothing else ( same seating depth ) and find a powder charge weight with that new powder that duplicates the 2700fps average." The reason a given load shoots well in a given rifle (ignoring such things as the shooter, rest, wind, etc) is the timing...

    Heavy Bolt With Mild Load

    I want to talk about the cases. Call the bottom row A, next row up B, third from the bottom C, and so forth. First case on the left is 1, center is 2, right case is 3. I see ejector swipe on A1 and A2, B1, C3, maybe on C2. Ejector swipe is caused by case brass being forced into the ejector...

    Vibratory Tumbler Recommendations

    I bought a Dillon 750 in the mid-1990s. In 1999, I thought I had a problem with it so I called and received a RMA number. Turned out that I didn't really have a problem so I didn't send it in. In 2022, one of the motor bearings failed completely. I called and they found the RMA and noticed...

    Case Prep: What are you using?

    Bench-Source Annealer. As you will be told, no doubt at very high volume, there are other annealer tools. Giraud case trimmer - separate cutter heads by caliber, lock rings on the case holders. I think that flash hole debur is a good thing - only do it once per case. 21st century expander...

    Case Gauges?

    Yup, you're right. I went back to the instructions and what you are describing is what they built it for. The minimum chamber gauge would be the correct Wilson tool. The only time I used brass where the headstamp was different from the caliber was Lapua 220 Russian neck-expanded to 6 PPC...

    Case Gauges?

    OP had a boom. He says because a case neck was too thick, weapon didn't go fully into battery. If I understood correctly, bullet diameter plus neck walls were a tight or interference fit in his chamber, bolt did not completely engage locking lugs, and bad things happened. My Wilson 308 case...

    Lesson-Learned: Primer Storage and Humidity

    Off Topic ... maybe "mayhem aplenty" Wasn't there a dancer who went by that name?

    (UPDATE) Which node would you use?

    Another point of view ... look at 38.6 and 39.0. Remove the wind from 38.6 and you get 39.0. Vice versa, add wind to 39 and you get 38.6. Maybe. Maybe that horizontal isn't wind. Maybe the barrel is moving at 38.6. More testing needed. Where is bullet 5 in 39.4? I see four holes...

    Shoulder bump inconsistency

    OP said that his once-fired brass measured 1.555 to 1.560. He says that he can pick a number (for example 1.557) in that range and reliably resize to -.002 or 1.555. Since his once-fired brass is coming out different lengths, he is asking what number in that range to use. People said ...

    BR case neck thickness?

    The combination of statements and your request seemed odd to me. You are spec'ing a reamer. You want to know the neck thickness of commercial brass. Your reamer guy can make the reamer neck anything you ask for - SAAMI or something else. I have everything from tight-neck BR guns, custom...

    BR case neck thickness?

    Do you want to turn necks? Do you plan to buy 6br brass or resize some other brass to your variant?

    Inline Quick Change Plate Mounting

    My bench top is two parts - 3/4-plywood on 4x4 wood legs with a 2x4 frame and some stuff I found that is about half-inch thick with plywood in the middle and hardboard laminated on both sides. The hardboard/plywood piece is glued to the top of the 3/4 ply. The QC bases are about half an inch...
