how often do you check your OAL? - Page 2

My tolerance is .005" for plinkers, zero for "other ammo"-let's not get into that debate.

For 10mm my target OAL is 1.260" If I get OALs from 1.255-1.265" I still sleep like a baby. If I get OAL variance of .01" I pull and reseat the bullet. Too long is better than too short. Too long= pressure reduction. Too short= pressure increase.

I check the first few out and then every 50 or so.

Loading lubed lead I will check every 50+ rounds. I load a lot of .40 and got burned once with lube build up in my seating die.

[-0.015"] On jacketed maybe every 500.

I set up to seat bullets, verifying OAL length of the finished cartridge, then don't measure again. Instead I monitor the seating die to insure that everything is staying tight during the bullet seating stage. It always does as it's easy to screw everything down tight and there are set screws that help keep it that way. We're talking single-stage press here, an RCBS Rockchucker.

Once the dies are set, I check OAL every 10 rounds and check the charge at the same time. I would reset if I were getting more than .001 variation. May seem kind of obsessive but after many years as a machinist, making medical equipment, checking my work is second nature. :)
