Sizing Down 6m/m bullets to .223 cal ?

[brstevns]

Asking for a relative. He was wondering if anyone has sized down 6mm bullets to .223 cal and if so how did they work?

Trying to size down 1/5 of an inch would ruin any Bullet cast or jacketed.

I haven't sized a boolit down this much before, so take what I post with a grain of salt as it is mostly speculation based on a little experience.

I would imagine that a 0.020" reduction would cause a loss of the lube grooves, especially if not prelubed. With lube in the grooves, the grooves may be retained, but would probably be distorted. I would be concerned about distortion in the boolit from uneven sizing. To accomplish this with the least amount of distortion, the boolit should be sized down in less that 0.005" increments. Larger increments would likely result in more distortion and difficulty in sizing. Even 0.005" might be too much for a hard boolit.

The simplest fix is to trade them or melt down and recast.

Nope, I haven't done it.

If you are talking jacketed bullets, that will be a difficult task with cast boolit sizing dies. If you tried it with a Lee brand bullet sizing die, you will likely wreck the die, as the Lee has a fairly narrow band that actually does the sizing.

If you are talking cast boolits, usually Rifle boolits are a harder alloy, so sizing them down will be a difficult task, unless you cast with a softer alloy, then heat treat after sizing, but that will make them easier to deform, which would be bad for the rifle's accuracy.

I've tried to size some 458 cast to to .452 and didn't have much luck. They resized but they were deformed more than I liked.

Thanks, That is more or less what I told him. Now maybe he will believe me.

Texas, LOL, your math is off my a factor of 10. Yes a factor of 10 (ten) the difference of .224 and .243 is 1/50th of an inch not 1/5. your decimal point slid on you move it to the left one place and you will be much closer.

A change that large isn't sizing, it's swaging. As others have said, this is not on its face a very promising idea; with a big enough press, the right dies, and enough power you can make a sewing needle by swaging down a 50 cal machine gun projectile, but it's just not a practical proposition.

KenYes, math is a foriegn language to me often. But .243" minus .223" = .200"- correct? If .250" is a quarter inch, why isn't. 200" a fifth of an inch? Either way, that's too much to squeeze.

Not quit .223 from .243 is .020 . Taught Math a few years when I was a much younger man. :drinks:

OK Thought you would like that.
You guys made me have to correct it.

OH! I get it now! (Memories of school). It'd be funny if I DID drink.....it's kinda sad otherwise.

Between both of us, I think we gave the members a good laugh! :killingpc

Laughing here! :drinks: All in good fun!

[jimkim]

I suppose if you sized it down to 20 caliber, and swaged(with proper bullet swaging dies) that back up to 0.223" it would work. That would be and awful lot of work.
