Set to .980" and plunk test to insure feeding adjust down if necessary .

For any 'new-to-you-bullet' to find your max usable oal:
Use an unsized Fired case. Actually have several if possible. Find one that your new bullet will seat into just barely far enough to hold it in place. Carefully push this into your barrels chamdber removed from the pistol. Push it in until it seats firmly on the case mouth. Turn the chamber down and carefully remove the bullet and case. Measure it .
Do this a few times with more spent casesto verify the consistancy. This is the length that contacts the rifling in THAT pistol with THAT Tbullet.
Subtract .010-.015" from that measurement and that's your MAXIMUM USABLE OAL in THAT pistol. Find load data that's at or less oal than your max. usuable oal and you're good-to-go.
This is much easier than it sounds once you try it.
Hope this helps.

You really don't need spent cases, or split cases, or dummy rounds.
What you need is a black Magic-Marker or a birthday candle.
And the first loaded round with a safe suggested Starting Load.
Seat long, then color or smoke the bullet and push it in the chamber.
Then keep seating slightly shorter, color or smoke again, and keep doing it, until the rifling stops rubbing the ink or soot off the bullet.
That right there is your Max OAL for your gun.
