I started making up rounds for my Jericho 941 .45 tonight, I am making up batches of 10 rounds at .2gr increments. The Jericho's have a short throat so I knew I'd would have to figure out the OAL and not use the number in the manual. I ended up at 1.185", at this length the bullet is just off the rifling and drops freely out of the chamber. However about 1 out of every 10 grabs the rifling just slightly and requires a light tap with my finger on the barrel, should I pull those rounds apart and redo them or are they ok??? Thanks, Andrew.

Take the one that is sticking and seat it 3-5 thou deeper or apply more crimp to it. You will have to play with it and keep doing the chamber drop test. To see if it is a case issue remove the bullet and do the drop test with just the case. I bet it is still and OAL issue. Don't be afraid to shorten a bit more but make sure to work up your load.
I'm using 230gr plated made by campro, I think your right that it's just a variation in the bullets.
yes campro plated (the ones I used) had variation. if you measure the length of 5-10 of the bullets with a caliper, you will find differences.
this is a bit annoying as some of the bullets were rounded and some were flat at the tip giving different OAL's for each completed cartridge
