Now I lay me down to sleep
A gun beside me is what I keep
If I awake, and you're inside
The coroner's van is your next ride
Less informative and far sketchier on the technical whys and wherefores than our "sticky".
Seems as if author didn't really understand either and it was a case of the ignorant leading the blind...
The ENEMY is listening.
HE wants to know what YOU know.
Keep it to yourself.
The perfect fitment for all centerfire revolver calibers is boolit sized .001" to .002" greater than groove diameter, cylinder throats sized .0005" to .001" 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?

K.I.S.S. has worked for me for about 30 years; size bullets the same diameter as the cylinder throats...

BINGO!

In revolver its almost more important to get the cyl throats right. Does little good to go 0.001" over groove dia then have throats 0.001" smaller than groove dia.

Unless the throats are 0.001" smaller than groove dia. My RBHSS had 0.4505" throats on the avg. It shot ok, leaded early. After opening them to 0.452", accuracy was about 50% better & now no leading.Originally Posted by mdi

This only works if the throats aren't already too small.
What are you going to do if you cast, size and lube a batch of boolits sized to the throats, then they sit for a year and suddenly the ammo won't chamber because the boolits have gained .0003" as they age hardened?
Ruger single action revolvers are notorious for uneven throat diameters. Can't size to uneven throats. Well, you *could* but that certainly flies in the face of the K.I.S.S. ideology.
There are good reasons why the arrangement I mentioned is near perfect for a revolver.

Yep. But I slug the barrels and measure the throats of all my guns before I shoot any lead. One important factor for shooting lead bullets is to know your gun. Otherwise it's just a WAG...
