Who knows the Lachmiller presision case comparators? i have two one was incomplete when i got it at an estate sale several years ago, then recently i got one that was in the box. thus found out they had sleeves that were machined to fit the mast diameter and set the caliber length. i got three of these sleeves with the one in box in 300 win 270 and 30-06. My question is , WHO knows these tools and able and willing to make sleeves in other calibers?
