1/32" above the case mouth is about right. For my gun - a vintage 1984 Colt 1911 - The correct COL is 1.238" for your basic 200g LSWC. Which is something closer to 1/64" above the case mouth; although like Mike, I've never actually measured it.

For your gun, it might be something different. Actual mileage may vary. You must perform a plunk test for your gun and that bullet to find the correct COL. Cartridge Overall Length isn't something that is variable in nature. It's either right or it's wrong. And it must be determined for each and every bullet type, and each and every gun for which you load it.
