Re: How much is too much Leade. ?

So what are the negatives if any of a long freebore when seating the bullet back in the case & having to jump the freebore? I'd like to hear from shooters that have direct experience, not guesses or assumptions. A shooting friend recently acquired a Pedersoli .45-70 Sharps with a lot of freebore. Al...

Re: Good casting session today

Wayne, was your alloy 20:1 or 20 to 1? 20 to 1 would give you a proportion of 21:1. 20:1 yields 20 pounds of alloy containing 1 pound of tin vs 20 to 1 which yields 21 pounds of alloy containing 1 pound of tin. Plainbase, It's 20:1 by weight or in this case actually 21:1 by weight meaning an alloy ...

Good casting session today

Getting ready for the upcoming Texas State matches. I believe I’ve got the casting technique pretty well figured out. Now if I can only shoot as well. The 140 bullets are from a BACO JIM410410M1 mould for a Browning .40-65. I have been using 16:1 alloy for some time but thought I’d try 20:1 for a ch...

An interesting simple casting experiment

I knew that the alloy temperature affected bullet weight but had never determined how much. Normally I went with the temp that resulted in fully filled out bullets using a specific alloy. Since I planned to cast sufficient bullets for 3 silhouette matches I figured I’d run a simple experiment. So I ...

Re: What is wrong here?

Being a long-term member I've watched this forum slowly deteriorate over the last few years. The problem is the forum owner/administrator hardly ever pays attention to the forum & it has been repeatedly down due to the lack of support. Therefore problems go unnoticed for lengthy periods of time as d...

Buffalo Arms (BACO’s) Moulds/Bullets: Changes & Decoder

Some of you may be familiar with or use the so called Jim Kidwell or “Kidwell” bullet in your .40 caliber rifles as I do in my Shiloh Sharps 1874 Sporter. Until recently Buffalo Arms (BACO’s) designation for the mould was JIM409400M4, which was incorrect since the 1st three driving bands are reduced...
