    I’m using it in 40 s&w and 30-06. In the Lyman 3rd edition cast bullet handbook there is lots of Herco data. In 30-06 with a 311291 the starting load for Unique is 12gr, for Herco it is 12.5gr. I shot a batch of this load this past weekend out I...

    The employee was very polite. This was a small flat rate box with ten pounds of pewter in it. Not very heavy. I had wrapped clear packing tape around it twice. She informed me that it could only be taped on the seams and flaps. What I had done is...

    The post office rejected a flat rate box for being over taped. The post office employee handed me a piece of paper with the rules on it. Basically you can only tape the seams. They can charge for the weight of something if they deem it over taped....

    I have done a simple cost analysis of what different alloys cost me. My cost for 30 to 1 (lead/pewter) is less than $0.80 cents a pound. My cost for 20 to 1 (lead/pewter) is less than $0.90 cents a pound. Between sail boat keels and old fishing...

    My type 99 has a generously sized bore. It slugs at almost .317” I size my bullets to .318. I have had good success with a gas checked Lyman 323470 and the Lee 324-175-1R. I converted Lee to a plain base mold. I’ve learned that the Metford...

    Larry, I have tried the upside down method. I ended up with bent bullets. I just couldn’t get a long round nosed bullet to start straight enough in the die. They ended up looking like bananas. JM

    I have to agree. The Lee shank on my 324-175-1R was so frustrating to work with. I finally gave up and drilled out the shank and made it a plain base mold (Thanks Ben for the tutorial thread on shank removal). Where as, I have a Lyman 323470 that is...

    Here you go. I think the photo uploaded sideways. But, you get the picture. No pun intended. This does the same thing as the NOE tool. You are just using your bullet seating stem instead of a Lyman style top punch. JM

    Here is how I seat stubborn gas checks. I use the bullet seating die. I disassemble the die, the seating stem is then screwed into the top of the die and then the die is thread into the press upside down. I then use the ram from a lee sizer to press...

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.
