I just got a new RCBS Lube-A-Matic 2 and am having problems with adjusting the depth of boolits, lube "flow" and boolit lube groove fill. as follows:
1) I installed the LAM as instructed by RCBS, although I moved the lock ring on the boolit ejector screw from the bottom to the top of the lower casting to deal with short boolits. Initially I set the adjustment at 1/2" under the die.
2) I am using a Lyman .430 sizer die and 421 top punch. The boolits are a gas-check design. A Lyman heater is installed under the LAM. The lube of the RCBS lube that came with the LAM 2.
3) I cranked the lube pressure handle down until I felt resistance, but no lube showed up when the boolit was inserted, even when repeated with the same boolit several times. I kept increasing pressure and varying the depth of the adjustment screw, and turned the heater on for 20 minutes.
4) finally I began to get signs of lube - smeared over the nose of the boolit, none in the lube groove.
I have the sense that this is a trial and error process, but maybe you all can give me some tips that will shorten the process.
