    Down rigger balls and bottom fishing lead, that I find at garage sales and thrift stores is a major source of lead for me, here in the PNW. It doesn’t seem to be pure, it seems to all have a bit of tin in it. A 3b pencil cuts and a 4b slides on the...

    I got a chance to shoot the first batch of fifty over the weekend. All fed and functioned just fine. I’m gonna continue crimping my 45acp with the 7.7x58mm seating die. It works and it speeds up production. The .472” crimp worked just fine. I’m...

    Sportsman’s warehouse is having a sale on 4 pound containers of WST. I got mine for $59.97 before tax. It is an “in store” sale. If your store doesn’t have it then they won’t ship it to you or transfer it to your store. It seems that they are...

    Wheel weights have been banned in this state for over ten years. The scrap yards will still sell other types of lead. It is against the law for them to sell even scrap wheel weights here. My local scrap yard is selling lead for .75 cents a pound....

    I think that I’m going to pull the bullet from the dummy and see how much if any it got swaged down. .472” seems to be towards the larger end of the crimp spectrum for the .45acp. I see numbers from .473” to .469”. I’m thinking that crimping them...

    I’m using a rifle seating die to taper crimp my 45acp. It is a 7.7x58mm seating die. A 7.7x58mm case is tapered from approximately .472” at the base to .429” at the shoulder. The seating dies taper is slightly oversized, when the 45acp case has...

    There used to be a tv show on MTV called “Pimp My Ride”. They would do over the top custom jobs on pintos and escorts! You could do something similar, with a common Plain Jane bolt action. How about taking a Savage 340 in 30-30 and doing a full...

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.
