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...

Re: Plastic wad orientation

If you put the sharp edges up (facing the bullet) it will do a better job of cleaning out the fouling from the previous shot.
BTW, I have no idea if that's true or not but sounds good. In any case, as Brent does, I keep mine up when using poly.

I realize that the majority of you guys are not FFL holders. But I thought I’d provide a handy reference for those of you that may have questions now and then. I have a Type 1 FFL (by far the most common) and have been somewhat confused about the other types and options prior to putting the followin...

Re: misfires

This was a later Winchester 45-90 with 30" barrel. I believe it was unfired when I bought it and not sure I ever did fire it before modifying it. Brian, I'm confused. You said the following earlier.

Re: misfires

OK thanks Just shot the gun today and its a pain to try to remember to move the ejector before putting another shell in. Brian, If your rifle has an NT in the serial number than it's highly likely it has the original design extractor. If so, to fix the problem you need to order a replacement extrac...

Re: misfires

Thanks Wayne. I'll add that section to my book. I do have one of Lee's springs, but this trigger hasn't been worked so I might send it in to him and get everything done while I have it apart. On another note, I have another Browning that I had rebarrelled to 45 2 7/8. When It came back it has had a...
