    I had a 1640 in 6.5x55 for nearly 40 years. Sold it recently to a young hunter to get him started the right way. Great rifle! A little on the light side, but they were meant to be carried a lot and shot a little. A 9.3x62 in the original...

    Interesting! But why not make them as a single piece - if the button can be pushed in, it can also be pulled out. You'll need a hollow-based slug for the rifling to grip the slug - unless you plan on imprint the rifling into the slug by force. I'm...

    A large caliber like 9.3x62 won't gain all that much going from 20.5" to 24" barrel. Quickload estimates around 90 fps with a 260 grain bullet and 62 grains Hodgdon H380

    As long as the gun has a cylinder bore I wouldn't worry at all. The swaging will be done by the forcing cone and the rest of the trip through the barrel will probably meet less resistance than an ordinary shot load. I have shoot a bunch of ribbed...

    Kraken, the more, the merrier! Slugs are fascinating... Clear hulls for slugs make sense, especially for safety reasons, that's why I only use roll crimp; With my sloppy way of handling things, sooner or later a slug load will end up in a pocket...

    I would think so. Normally I have always added a 1/2" felt wad between the seal and the slug. I'm trying to keep things as simple as possible which is why I skipped the felt wad. The slugs still grouped well, under 4" at 55 yards, but since I was...

    Longbow. The "cavities" has been there all the time. The first design was too weak so I added more support. The reason the wads are not solid is that the plastic shrinks too much which prolongs the solidifying process as the plastic loses...

    Reloader 12 is listed in the Quickload program. I ran a test for a 270 Win with a 130 grains bullet and 48 grains of RL 12 although it's a bit on the fast side for this caliber/weight. The pressure was 60.800 psi. I then tried same powder weight...

    Tested the difference between deep/shallow crimp with a heavy slug (1-1/4 ounce) over 34 grains of Blue Dot. At 1450 fps this is a "warm" load probably above 10.000 psi. As with the fast powder test the deep crimp resulted in slightly faster speed...

    If the ball matches the diameter of the datum line, its center will always be above the datum in an angled (conical) hole. The exact amount is depending on the angle - I'm afraid trigonometry must be applied here... B.I.S.: My avatar is...

    I've been contemplating a suppressed shotgun design for several years: Most of the suppressors for shotguns add quite a bit of length and weight to the gun and only works on single-barreled guns. I had an idea of modifying an ordinary...

    The correct way to measure the chamber length of a bottleneck cartridge is to have a ball bearing of a known size resting on the angular flats of the chamber shoulder - then measure the distance from the chamber face to the top of the ball. The rest...

    Apparently Alliant, Norma and RWS powders are all made by Bofors. This list gives a comparison between them. Powders on the same line can be used interchangeably. http://www.bushman.dk/sider/genladning/krudt/krudttabel.htm

    As mentioned above, it's partly a grain problem. Try drilling perpendicular to the grain, it may even result in a more sophisticated look:wink: Use a two component epoxy, like boat builders use, it's extremely strong and will bind on a smooth...

    I made a bunch of buckshot molds of all sizes for a group-buy years ago. The molds were filled from center stems with the cavities arranged as close as possible Did quite a bit of testing before starting on the final molds and the best results were...
