    If it was all clip on WWs you probably have a ternary alloy of 97% +/_ lead, 2 - 21/2% antimony, .05% tin and some other trace elements. If there was stick on WWs in there that will raise the % of lead depending on the % or stick ons as they...

    Lee's book gives a "factor" (VMD) for powder density based on how much 1 grain weighs cubic centimeters. The lower the figure the more dense the powder will be and thus will occupy less space with a given weight in a given cartridge. The VMD...

    Foraging shot 45-70 load I use a fired R-P case but others work just as well. Deprime and reprime with standard LR (make doesn’t seem to matter) primer. Drop 10 gr of Unique over primer and then gently push a gr of Dacron down on top...

    No doubt as a lot of cast bullets were used by military shooters. Earliest I read of Ideal's (the mould company name) #1 alloy was in Lt. Townsend Whelen's book Suggestions To Military Riflemen (1909) originally published in 1909.

    The 358W can give feeding problems in the SR Mauser actions (M93 - M95) as they do not have the correct case taper, same as the .308W. I had a heck of a time getting my Oviedo M93 to reliably feed .308Ws if 3 or more rounds were in the magazine. ...

    In most circumstance with commercial 30 caliber rifles.....no. In 14" twist barrels reasonable accuracy can be had at 2500 fps that alloy if cast and loaded correctly. Otherwise a harder alloy is needed for best accuracy. With a...

    If you can get the tin then my suggestion for the alloy you have to make 94/3/3 alloy remains. Next purchase get the Lyman #2 alloy and lead. Then just mix the #2 with 40% lead for the 94/3/3 alloy and you won't need any additional tin. That...

    "The original 55 gr ball ammunition in the 5.56 was slightly unstable in 1/12 twist, and... a little known fact, was that the lead core was melted by the hot powder gas when the bullet exited the muzzle." Gotta say I've never heard that one...

    As a suggestion I'd add 50% lead to that and then 2% tin for a 94/3/3 alloy. What mould/bullet are you casting for it now?

    What I'm really asking for is how the Lee listed BCs were determined, by computer or by actual tests?

    Years ago I would buy 1,000 bullets unsized/unlubed from a commercial cast in Oregon (Liberty Bullets). They were 8mm 160 gr PB'd bullets. I sized at .325 and lubed them with Javelina and loaded them over 6.5 gr Bullseye in cases formed from '06...

    Can you be more specific as to where on Lee's site? What I get from leeprecision.net is; We don't have ballistic coefficients for our bullet moulds. The primary reason is that the percentages of material used in the mold is quite different from...

    What I noticed when I resized the cases was that the die met more resistance at the bottom 1/2" or so on the case. That is normal if the pressure is sufficient to obturate the case at that point. That area of the case is called the "web" and has...

    I also have a good amount of H4895 and trying to get velocity on lighter bullets with out gas checks. H4895 is not a good powder for 130 gr PB cast in the 30-06. Haven't used TG but Unique is what I used in the past for 1400 to 1500 fps with...

    BCs (Ballistic Coefficients) are mostly derived from computer programs based on the bullet drawing. There are many things that can adversely affect the actual BC of the bullet in flight.......the computer programs do not take those into account. ...
