One of the guys that works where my wife does gave me a brass pre-measuring loader today. The only thing is he didn't remember how many grains it loads. Here are the dimensions:
The reservoir is 5 3/16" long x 1 3/8" across
The laod tube is 2" long x 1/2" across
Do any of ya'll have one of these and do ya know how many grains of powder it feeds to your MZ?
