    JM7.7x58 replied to a thread Identify this bullet in Cast Boolits
    I would use data for the Lyman 35891. It’s a button nose wadcutter at 148gr. It has a crimp groove and is not a flush seated wadcutter. Weight is almost the same. I use this data for the 150gr 358477 SWC when I load it in 38 special. JM Lyman...

    I made up a few dummy rounds tonight. I tried to crimp with the Lee push through sizer, it sorta worked. I ran it down about 1/16" past the rim. It did flattened out the flare, but it left a funny looking ring that wasn't even all the way around....

    Battis, I’m in the same situation. I bought a set of RCBS dies on eBay for .32 long / .32 H&R Mag. I assumed that this set would deprime, size, expand, and crimp the 32 acp. Well you win some and you loose some. This set does most of those...

    A 30 amp clothes dryer circuit will be fine. In five different houses I've lived in over the last twenty-five years, that is what I have used. I have run SMAW, GTAW, and GMAW on a 30 amp circuit. I wouldn't try to run 5/32" stick. I wouldn't try to...

    Yes, I do. Why do you ask? I just started to cast for my stock first generation M&P 40 shield, barrel slugged at .4015". I was able to fire off my first batch before the COVID-19 stay at home orders came out. Lee 401-175-TC, as cast .403",...

    I started with a Coleman camp stove and an eight inch cast iron Dutch oven, I used a large kitchen ladle with a 3/32” hole drilled in the bottom to cast. I then bought a lee bottom pour. For me buying the bottom pour pot was a big mistake. I now...

    If we go with the .001” to .002” oversized theory. Then .357” would be about right. I have sanded out a few Lee sizers. A dowel, a bit of masking tape and a piece of 600 grit make quick work of it. JM P.s. I have run .0025” oversized without...

    I am currently playing the “learn how to make .40 s&w go bang everytime game”. In an effort to reduce variables I have sorted out one headstamp of 40 brass for load development. I hope to start using mixed brass once I get this round figured out....

    I don’t think that there is really any difference mechanically when depriming. There is a difference when priming on your press. Hornady shell holders will not work with the Lee on press priming system. If you ever want to Prime on your RCBS you...

    That old revolver pretty much lives in the back of the safe. I have a nice Security Six that replaced it 15 years ago. I think that I will try to stretch that spring a little. Thanks for the hint. JM

    While I don’t have decades of experience. The few thousand primers I have seated on my Lee Classic Cast have all been touched by my hands. They all went off. It seems that there are two camps with primer handling the “rubber glove and tweezer” camp...

    The only thing that I would change for sure is my first lead pot purchase. I regret buying a Lee 20# bottom pour pot. Mine is currently "adjusted" so that the slide will not move, basically plugging the pot. I am now laddle casting, and very happy...

    ^^^^This is a great idea!^^^^ If you don’t have round nose pliers (they are great by the way, I have two pairs), you could insert a Lee Case Length Gauge into the neck of the Bee and clamp down with some “soft jaw” vise grips. I like cut up...

    We have a bush that grows around here called ocean spray, it also goes by the name iron wood. The natives used it to make digging sticks, second year growth makes good arrows, and if glued at the handle a good bow can be made from it. I use a stout...

    I really value the Lyman Cast Bullet Manual 3rd edition. It has a lot of Herco data. I just recently picked up 12 pounds of Herco for a great price. Between this website and my copy of the 3rd edition I did a lot of research before my purchase. I...

    JM7.7x58 replied to a thread Preheating mold in Cast Boolits
    I use a cheap electric Panini sandwich press. It has a heating plate/element both top and bottom. I paid like $7.00 for it at the thrift store. I start heating my molds at the same time as I turn on my Lee 20# pot. By the time the lead is melted...

    I sized and tumble lubed 300 Lee 452-230-RN-TL and 200 Lee 358-148-WC-TL. I then loaded two dummy rounds for my new to me 32 ACP Beretta 81. Did this without having any dies, they are in the mail. I used the NOE expander for my 30-06, to open the...

About JM7.7x58
Long time listener, first time caller. I've been reading this forum for years. Very grateful for all the information I have gathered here over the years.
I was given an old Type 99 Arisaka over a decade ago by a family member. It had been disasembled back in the 70's and was missing half of it's screws. I got it put back together and am now getting ready to cast boolits for it and for 38 special/.357 mag.
