if a boolit is sized too large? Other than the obvious that it won't chamber, are there other signs? I have .358 and .359 for my .357s. I need to unplug one set of holes to lube a new boolit and I have a new .359 that I haven't plugged any holes yet.

The pistols are S&W and I don't have a fixture to measure them. I also have a Marlin .357.

I hope this question makes sense.

I doubt .359 is too large. A lot of mine as cast are .359 and they do well. I pan lube, and size to .358. Slick.
In a revolver, if it is too big, I have had shaving before. The forcing cone does a lot of sizing.

As long as the cartridges chamber, the bullets aren't too big. I don't think you will see any signs of leading etc from a too large bullet, only one that is too small, too soft or too hard. In a rifle you might see high pressure from a too large bullet, but I don't think you will in a revolver.

The thing I've notice with large diameter boolits is my seating die bell remover (crimp) wants to grab the boolit too soon and cause problems.

I very seldom size my 357's and they have been dropping lately on the average of 360. I don't have a leading problem in my Ruger or my Marlin.

.359" is my standard size for both the .38 Spl. and .357 mag. Should work just fine for you.

What are the signs? Possibly poor (or poorer) accuracy and an increase in pressure as well.

each .001 in size only raises your pressure 250-300 psi.
so unless you are shooting 8 grs of bullseye....grin.
i wouldn't get too excited about it, if it will chamber it will be fine, your cylinder throats will size it just right for you.

I would think that sizing takes a certain amount of time that otherwise wouldn't be required. During that time, different things would happen depending on circumstances that otherwise didn't. And you get a faster or maybe a complete seal too. Most of the time all I have seen is a change in ES either way in a gun with matching dimensions. But I seldom run full power with cast in a handgun.

As with anything you try, start low and come up.

I have started sizing to .359 for my Charter Bulldog 38 Special and find improved accuracy over the .357 and .358 sizing I had been using. I would shoot them as cast (.3595 with three molds) but I prefer to lube with the lubesizer. .359 does not bulge the WW and RP cases and chambers easily. Some military cases I have do bulge slightly, but still chamber with no stickiness at all. DALE
