223 barrel slugging question

[Muddydogs]

I have slugged a few pistols in the past and tonight I slugged my 223 Ruger M77 heavy. I started the sinker slug at the muzzle and found that by the time it was started it pushed through the barrel very easy, no real resistance. Is this normal? I realize that even a .380 slug has a lot more surface area then the 223 especially when using pistol slugs made from lead in once fired brass but I expected a little more resistance. The 223 slugged at .225 which seams on the large side of things.

many of us go both directions just in case one end is tighter than the other.

It could well be you're right about .225 and are about to be in the market for a fat .22 boolit and a .226 or .227 sizer.
Yep the .22s do slug easily, but are hard to measure....unless you have .22 caliber fingers.
