HI All,
I'd like to duplicate the Gator .30 cal copper gas checks. It seems that I have found :
Gator material Thickness - .017 I have only seen this number once can anyone verify. I don't have a micrometer.
I found a source of .016 ( 12 oz ) copper delivered that should yield .30 cal checks at a price of $.014 to $.015 figuring 4 checks per square inch.
This is less thick than Gator, but I assume this is because of material variations as .017 does not seem to be offered for sale.
Has anyone punched copper this thick in either the Checkmaker or Freechex III
without tool modifications?
If it needed modification, what did you do?
I would like to stay with copper. I read that some folks verify that it preforms better at the higher velocities, which is where I would like to end up if I can someday cast good enough quality for that level.
Thanks Matt
