    That bullet has a .95 +/-" length so stability out of a 14" twist should not be an issue. However, the bearing surface length is 50% or less. That leaves a lot of unsupported bullet hanging out from. You might try HTing or WQing the bullets to...

    I have always used .314 cast boolits, and .312 Hornady jacketed in my Mosin's. I always work my loads up, so I've never had any problems with the data listed for .308 bullets. And no, I doubt if the manuals will ever change their data. I've also...

    #2 alloy contains 90% lead, 5% antimony and 5% tin. Given COWs only contain 2 - 3% antimony I never could figure out how 9 1/2 lbs of COWWs plus 1/2 lb of tin could make that alloy. I have used quite a bit of #2 alloy made with the linotype,...

    That was the myth for many, many years. I believed it too because it sounds reasonable. Problem is, it doesn't work out that way in reality. I've spent a lot of time, effort and expense trying to determine, by actually measuring the pressures,...

    We're not going to get any "pressure signs" at 38 SPL pressure levels. If you do then you are probably above 357 Magnum pressure levels. However, this is where the chronograph comes in handy. If you're using a different bullet than the manual,...

    The 327 dies may not crimp unless they were made to load the 32 S&WL, the 32 H&R Magnum and the 327.

    Oh, I'm "up to speed on it" alright because I've measured the psi. If you have a load, particularly a top end load, and use another bullet, even if the same weight, that seats deeper into the 38 SPL case the psi will be higher. As I've posed a...

    Agree with Bookworm. I've been shooting cast in MNs since the '70s when I got my first Lee single cavity C312-185 mould (have a 2 cavity now also). Mine drop excellent bullet cast of COWWs + 2% tin at .313+. I GC with either Hornady .30 cal GCs...

    One would have to know what was meant by "optimum".....optimum for what? If in a Handgun with a single load that probably is pretty close. However, unless one wants to register a carbine with a barrel shorter than 16" as an SBR, pay $200 to BATF...

    Over the years I've fire lapped numerous rifle barrels. I've done 22LRs, 6.5s, 7mms, 30/31 cals and 8mms. Mostly milsurp barrels but a couple inexpensive commercial barrels also. Accuracy did, in fact, improve with all of them. No, it did not...

    35 caliber in a not faster than 14" twist would make a very good cartridge for use with cast and jacketed and would fit your criteria nicely.

    The reason for that is Blue Dot requires a certain pressure level from ignition and rise to pressure to burn efficiently. Blue Dot, like many other powders, is not suitable for reduced pressure loads in the pressure range many cast bullet shooters...

    I consider a "mid range" 44 Magnum load to be a 240 - 255 gr cast bullet at 900 - 1050 fps out of a revolver, depending on barrel length. Unique, at 8.5 gr has always served me well producing that velocity level with excellent accuracy. I've used...

    Agree with derek45, it's an urban or barracks legend. I suspect it stems from those who associate the caliber designation as being the cartridge, i.e., "7.62" as in 7.62 NATO, 7.62x54R and even 7.62x39. I even heard a well known anti-war protester...

    I use 8.5 grains of Unique for 240-250 grain cast boolits. It's a decent mid range load, and very accurate in my Ruger Blackhawk.

    The difference is in the malleability of the alloy. A true 16-1 alloy is a binary alloy of lead and tin with no other metals. This alloy will not harden by WQing or heat treating. COWW alloy + tin is a ternary ally consisting of lead,...

    You might come close to .313 IF it's an older Lyman mould AND you add 2% tin to your COWWs. Also casting with the alloy temp at 710 to 725 and pour the alloy in allowing it to roil back out leaving a good sprue, even if some runs off the sprue...

    Using wheel weight alloy you will probably not get any expansion. With the 1650 fps load the nose may fracture and slough off if solid enough bone is hit. In COWWs there is too much antimony and not enough tin for reliable, if any, expansion at...

    Larry Gibson replied to a thread Ugh! Too big! in Cast Boolits
    The bullet inside the case will have been sized down. How much? You'll have to pull one to find out but I suspect the sized portion will run .451 - .452. I suspect any pressure increase, if any at all, would not cause any pressure problems.

    If the BHN is 7.5 then the alloy is closer to 40-1. As mentioned, a 16-1 alloy should be in the 10+BHN range.

    I sometimes use it to lube paper patched rifle boolits, it works pretty well in that application. It works OK for low velocity pistol loads. Honestly, I think LLA works better for the pistol boolits.
