-INSTRUCTIONS FOR USING THE WILSON …

1 - instructions FOR USING THE WILSON CARTRIDGE CASE TRIMMER- To save room, trimmers are boxed with the cutter and bearing assembly reversed. To place in operating position, loosen the cutter bearing screw under the base and turn cutter and bearing together 180 degrees. Tighten screw securely. The trimmer is best held in a vise, or Sinclair mount, which will hold it in proper position and high enough from bench for handle clearance. Cardboard or blotting paper will protect trimmer base from vise jaws. In setting the trimmer for correct case length the WILSON Cartridge Case Gage is recommended in those calibers for which it is furnished. The case trimmer should be adjusted to produce a case length, which will register flush with the lower step of this gage. In all other calibers adjust the trimmer according to the TABLE OF CARTRIDGE CASE LENGTHS furnished below. With a little practice you will develop considerable speed in putting cases through the trimmer.

2 In our use of the tool the operations are done as follows. Drop case in case holder and tap head end on hardwood block. Hold firmly in trimmer with case head against stop screw and twirl cutter until it stops cutting. Remove case by tapping mouth on same block. NOTE: Case holders have a groove turned near head to indicate at a glance which end is the head end. The trimmer is now being furnished in .38 Spl., .45 Auto, and other pistol calibers in which the cases have practically no body taper. These cases require a special type hardened case holder which is constructed very much like a sizing die and cases can t be bumped in and out like most rifle cases but must be forced in without damage to the case mouth. The holder is counterbored at mouth end for cutter clearance. Users will find the trimmer somewhat slower on pistol cases than on rifle cases but it will produce a very uniform case length with consequent perfection in crimping.

3 All trimmers are now made with a rake-tooth cutter. This cutter has the advantage over a straight-tooth cutter of cutting faster and with less pressure required and will be found superior for all purposes within reason. The cutter has been designed expressly for the job it has to do, which is to face off amounts from zero to about 1/32 . If desired to face off larger amounts, as in cutting 06 brass back to 8mm length, it may be necessary to adjust the stop screw so that the material will be removed in more than one operation. By doing the job in steps the cutter is allowed to contact the stop often enough to steady the cut and prevent grabbing . Our hardened steel burring tool is a recommended accessory for this trimmer. It is used by hand to chamfer the inside of the case mouth and to remove the sharp edge outside of the case mouth after trimming. One burring tool serves for all calibers from .22 to .45 inclusive.

4 * The last burring operation done on one case should be the first done on the next. In this way you reverse ends with the burring tool just once for each case. The new standard burring tool serves for all calibers from .17 to .45. Occasionally we have a case holder returned as defective , because the case drops in clear to the head and still is not tight. Almost invariably these so-called defective holders are in .30-30, .32 Spl., .300 savage, or . Winchester. Standard holders in these calibers are made for FIRED cases and cannot be used for both new and fired. Holders for new cases in these calibers are now stocked, are marked NEW CASES and can be had at standard prices. Unless holders for new cases are specified, however, the standard holder for fired cases will be furnished. In almost all calibers only one holder is required for both new and fired cases, the definite exceptions being the calibers listed in this paragraph.

We would suggest that your case trimmer be adjusted to produce a case length .010 under maximum.

7 The lengths are over-all, including the rim, where the case has a rim.
