![]() But my brass seems to be well under the 2.060 I measured. So my question is that it states above to trim to slightly under your actual chamber length. ![]() Then I measured about 15 or so of my once fired cases. ![]() 260 chamber to 2.060 using the sinclair gauge insert. Once we have our cases all trimmed to a uniform length to our specific rifle we now need to deburr the mouth." Now until this dimension were to change (barrel removal, etc.) trim your brass just short of this measurment, instead off BOOK trim to length specs. It would probably be a good idea to repeat this measurement three times and average all three readings. Measure the overall length of the case, head of the case to end of the plug and note that measurement somewhere obvious & permanent in regards to loading for this particular rifle. It has hit the end of the chamber and been pushed back into the case by the action of locking the bolt. remove the case gently without bumping the gage. Seat you plug gage into the case- long.Ĥ.ease this round into your weapon and fully close & lock the bolt.ĥ. take a scrap case and trim it WAY back with your case trimmer, say. So I am a little confused on trimming to actual chamber length of the rifle instead of just cutting your brass to book specs.ġ.
