[QUOTE="britz, post: 254207, member: 7865"] I don't use the Forster, but I use an RCBS and I beleive they are somewhat similar. You should be able to get within .001" from case to case. If you are having trouble getting it close than I would look at the shell holder and see if there is a problem there. Also, I assume that you are using a 22 caliber pilot on the cutting head. Having too small of a pilot, or none at all will allow the neck to wobble during cutting and you may then cut the case irratically. Generally speaking trim lengths will be .01" shorter than the maximum case length so I think you would be trimming to 1.75". for a 223 (admittedly I don't load for the 223 however). When I set up my trimmer I start with a case that is too long and set the trimmer so it starts to cut. Then I measure the case with a standard dial caliper and if it is too long I adjust it to cut shorter little at a time until you get to the right length. Seldom do I wreck a case due to over cutting when I set the cutter up. The RCBS has a screw type fine adjustor for the cutting depth with hash marks on the ring so I can keep track of how much I am adjusting the cutter. If the Forster doesn't have that fine adjustment then I would wait for some other advice. Good luck, Mark. [/QUOTE]
