I am thinking of getting a new case trimmer. Something better suited for high volume. I have both a Forster and Lyman. I am looking at the RCBS mostly because their stuff works. But am wondering how many shell holder thingys I have to buy. Trimming mostly 30-06 family and 30-40 and 30-30, 303 Savage, maybe 222 Rem. I guessing 5 or 6 shell holders. Any opinions on this appreciated. How about 50 cal stuff? Is the cutter big enough? thanks in advance
