The directions say to use a chamber headspace gauge to set up the sizing die. Which gauge should be used ? A go gauge, no-go, or field ? Setting it up for a M118LR 308 sniper round if it makes any difference.
This works fine for bolt actions. Your not going to shoot the reloads out of the DROP-IN CASE GAGE are you?You can do the exact same thing by using your rifle itself.
Just set the die so you can feel slight resistance when closing the bolt on a sized case.
That's closer to being right for your rifle then using a DROP-IN CASE GAGE set to SAAMI "close enough to fit everything" specs.
This works fine. Your not going to shoot the reloads out of the gage are you?
What threw me off was Dillon saying to use a gauge to set up the dies in the first place.
The rifle's chamber will tell you if it'll chamber. It won't tell you if you'll be overworking your brass or otherwise creating an excessive headspace condition. A case gage/comparitor/case mic will.
uh oh...........you'll be overworking your brass or otherwise creating an excessive headspace condition
AgreedWell stated.
Why horse around guessing?, get a case gage and measure what you are doing!
