    I had a 22A, and while I really liked it when I owned it, it was finicky with ammo. Federal lightning was my goto plinking ammo for years and years in other guns, but the 22A didn't like it. The only cheap ammo it really liked was CCI blazers and...

    Larry, I can't see anything in Glen E. Fryxell's article "Cast Bullet Alloys and Obturation" about calculating/predicting when failure occurs, it is all about when Obturation starts. Why are you trying to point out that the formula fails at...

    GTIV, Welcome to the forum. What caliber? if it's a 9mm, that can be a troublesome caliber to load with cast boolits. You may have success on one gun and failure in another. There are a couple threads about loading cast boolits in 9mm that...

    Larry, You are the last person I would ever try to argue with, and I won't. With that said, the formula is not for calculating a Maximum or Fail Pressure, it is for figuring Minimum pressure an alloy of given BHN will obturate the base of the...

    Good question, I have no idea. I have researched a little bit about ZAMAK 3 as a adjunct in boolit alloy. It should be easy to research it in regards to Plating. good luck.

    The vast majority of American made zinc wheelweights are cast with ZAMAK 3, which has 3.5-4.3% Aluminum and 0.25% Copper, if it is RoHS Compliant. Foreign manufacturers may use a different zinc alloy.

    compress means something different than what I think you are asking. I would use the term "slump" when referring to a boolit becoming shorter in length, which happens to the unsupported nose when a condition of too much pressure occurs. But...

    Last week, I finished loading a bunch of 41 mag ammo, that I had cast for. Most of the boolits were cast in the last year. But as I was reorganizing the storage area, I found some that I cast in 2011 from a Saeco 411 four cav. mold, the batch was...

    JonB_in_Glencoe replied to a thread Ornery Brass in Cast Boolits
    If the primers aren't crimped and/or sealed, then I suspect corrosion. Did they spend anytime on the ground at a outdoor range, being subjected to rain or dew? The only other thing I can think of, is wet tumbling and not being dried out completely...

    JonB_in_Glencoe replied to a thread Bee's wax in Boolit Lube !
    That will result in a lube very similar to NRA 50/50 ...So yes, it will work well as a boolit lube, but you may need to modify your technique to apply it.

    I lube all types of molds with a Sprue plate lube, the one I use is similar to a fully synth two stroke oil.

    You are correct, I have it mixed up. Oops. :oops: I will admit, this is my assumption. I have a few old Ideal GC style molds. When I install the old style brass GC's and run the GC'd boolits through a Lubesizer, the GCs go on nice & square...

    Bzzt, welcome to the forum. That's a good question, maybe send a private message to Gunload Master.

    I agree with Winelover. The other factor he doesn't mention, is the water warms as more boolits are dropped in. Oven heat treating, all the boolits go into the water at the same time, water is the same temp, which makes for uniform hardening. ...

    You could devise a vibratory gravel sifter (electric or manual), but there would probably be so much powdered lead in the mix that could become airborne, I would think it would be too risky (healthwise), for the reward.

    Yesterday, I also was pondering the meaning of life, the universe and everything. I was loading some 410610 (a 41 cal SWC very similar to the 35 caliber 358156). The previous day, I had worked up a load to Max for my 3" 657. The GC'd 410610...

    Old Ideal/Lyman GC's were designed for boolits that were cast from old ideal molds....and some old molds marked Lyman. If you measure the Shank on boolits from older Ideal/Lyman molds, they are a tad larger. The Thin Ideal/Lyman GC are made from...

    I am loading a batch of 'snappy' 41 Mag today. I loaded several different charges of 2400 in some test rounds yesterday, to work up a load. I wanted to find the limit for my 3" 657 with the Lyman 410610. and the winner was 17.7 gr. It was 15...
