    Flush seated DEWC 148 grain 2.7 grains Bullseye. I use AA No.2 2.6 grains with the same boolit. Deep seated wadcutters reduce case capacity, and allow small charges of fast smokeless powder to burn efficiently. 38. Special started off it’s life...

    Thank you Springfield. I like this idea. I was going to go with the mold idea because I wanted repeatability. I can make a ladle that will give me this repeatability. And I already have a muffin pan. Thread closed, JM

    I’m gonna make “Pewter Nuggets”! I’m looking for a scrap mold. Cavity size isn’t important; I will modify/drill to make cavity’s that cast the weight I need. Two cavity would be great, but beggars can’t be choosers. I will pay shipping, plus...

    JM7.7x58 replied to a thread Cases bulging... in Cast Boolits
    Pull your boolit, size the case again, if the bulge is gone, then it’s not how your sizing, it’s how your crimping. JM P.s. I vote for trimming down your brass. It will reduce your case capacity, and get that 3 grains of Trailboss burning right.

    Winchester and RP brass (no nickel, no +P) go in my “Wadcutter Can”. Everything else goes in the “Everything Else Can”. I have had problems with some brands of brass bulging and not chambering when I seat wadcutter deeply. Since I started sorting...

    Washington has been doing some pretty silly stuff. I hope lead doesn’t get banned up here also. Washington banned lead COWW ten years ago. However, they have left fishing weights and boolits alone. JM

    The Japanese made the Type 99 with all metric threading. 6mm x .75mm is not a normal metric thread size however, I had to special order the tap and dies. Not something you can go to the hardware store and buy. From what I have read the Spanish...

    I had to make a rear screw for my Arisaka. The screw started out as a long 6mm bolt. Grinding on the head was done with a 4 1/2” right angle grinder and a drill press. I rotated by hand until it was 12 sided, then turned on the drill press and...

    That is very cool. Good score! Just a little hose safety. That hose that came with your pot may not hold up for very long using propane. There are two different grades of hose. I have included a quote from one of the hose suppliers below. ...

    I don’t know if the original poster has a scale or not. Yes scales are great to have. I own two and want more. I will say this though. My main powder scale is a lee safety scale. It only goes to 100 grains. I later picked up an older (and beat...

    Used nonfunctional/rebuildable Blue Streak Sheridans, built before 1978, are going for $75 to $95 dollars on EBay. When I’m pricing things on EBay I will sort by “completed” sales/auctions. It is a more accurate way of pricing items. I’m all for...

    Brand of tool is not all that important. Many Chinese/harbor freight/grizzly/midway cheap calipers can give good service for the work we do. Some right out of the box, others after a disassembly, cleaning, deburring, and lubrication. I have both...

    Good shot! I have been shooting wasps in the backyard with my son’s “Red Ryder”. Glad it’s a repeater. I average about fifteen bb’s for every wasp shot. JM

    Ed is a straight shooter. He had an old press that he wanted to get rid of, and was giving it away for free. A very generous thing to do by the way. I drove to his house and picked it up. Thanks again, JM

    I would boil a pot of water. Remove it from the heat and set that plastic bottle in that hot water. When it gets syrupy I would add some mineral spirits. You may have to replace the hot water a few times. I would roughly guestimate how much is...

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.
