Hello Boolit Buddies:
When sizing a cast boolit for the throat, do I size for the same dimension of the throat, or do I size for .001 less (or something)?
Thanks

Size so that the boolit will push through with some resistance. I have found a loose fit to be better than one that won't push through. My loads tend to be around 1000 fps and a bhn of 10 works well.

Just push through. I think my goal is .0003" under throat.

I like to be .001" over the groove dia. That should be slightly less than the max throat dimension.
Are you asking about rifle or revolvers? Different answers.
Disclaimer: The above is not holy writ. It is just my opinion based on my experience and knowledge. Your mileage may vary.
With a revolver, that would be more often than not after honing throats...
Centerfire revolvers work great with boolits sized .001" or .002" greater than groove diameter, throats sized .0005" to .001" greater than boolit diameter, so you have a push through with the fingers fit in the throats with light drag. Semi auto boolit diameter .001" or .0015" greater than groove diameter, throat .0005" greater than boolit diameter.

Got a .22 .30 .32 .357 .38 .40 .41 .44 .45 .480 or .500 S&W cylinder that needs throats honed? 9mm, 10mm/40S&W, 45 ACP pistol barrel that won't "plunk" your handloads? 480 Ruger or 475 Linebaugh cylinder that needs the "step" reamed to 6° 30min chamfer?
