Got it. I've been consistently getting 1.586 to 1.588 with the 110 gr (the Fiocchi factory ammo I've got is even shorter, with their 142 gr flat nosed). I'll play around with it.

With regard to your question "Any idea how many turns ....". If you know the thread pitch of the adjuster knob, then divide it into 1" and that will be the change per revolution. I use Dillon dies and the whole die is adjusted up/down for seating. It is an industry standard 7/8" x 14 die. Since the pitch is 14 turns/inch, each full revolution of the die is 0.071 inches.

This was probably one of the dumbest questions posted EVER, so I'm sorry to have wasted your bandwidth. There's really hardly any adjustment required at all.

I loaded up a dummy round with the 158 gr boolit without touching the seating die at all and it came out exactly at the same length as the 110s I've been loading. The fact that they're both Hornady no doubt made this easier/less complicated, but OAL is OAL.

ESquared - You mentioned using Hornady. Brass or bullet?
I tried reloading some range pick-up Hornady 357 brass and found the case to be MUCH shorter than the Federal or the Starline cases I purchased.
Just Fyi.

I know that to be true for the LEVERevolution 45-70 cases .... they can be reloaded but only with the same style bullets Hornady loads at the factory .... no doubt, that is by design .... I have been told that is true for other calibers, thanks for corroboration

Florida_Cracker, those range pickups must have been loaded with FTX bullets.

According to Hornady's Handbook, Ninth Edition, their .357 magnum FTX bullets require a case length of 1.24; all other bullets use the usual saami specified case length of 1.28-1.29 (max).

This recommendation is loosely related. When changing die depths to accommodate loading different bullets or different brass, i.e. switching from .38 Special to .357 Magnum brass, I measure the distance from the top of the die to a fixed point on the tool head or reloading press with a dial caliper and log the information in my reloading bench book. That way I can save time by adjusting the die to the recorded measurement instead of making adjustments through trial and error. It's saved me a great deal of time when switching from one bullet profile to another.

If you really want to save time swapping from 38spl - 357 you can get a washer machined to the correct size that goes under the die and simply remove or replace it when swapping. Redding used to sell them not sure if they still do.
