All I can say is"WOW" I got my Prometheus powder measure about 2 weeks ago , and this thing is incredible! I can load a round every 10 second , and do it with 1/100th of a grain accuracy. Don't know if you have seen the machine but there is a pretty good video on You Tube. If you want to know particulars( price etc) give him a call his name is Brand Cole 425-239-9100. He is a super guy and an amazing engineer and craftsman! I can truly throw a charge seat the bullet and it has another charge ready to throw to .01 grain, not aprox . .1 like achargemaster but .01! You can get that accuracy with the top of the line digital scales and the lil dandy(that's what I used before) but about 3 to 4 times the time. No I don't get a kickback or anything this is just one of the coolest things I have seen or used in my 65 years. You long range guys would love it! Sorry, sometimes us old guys ramble on! JVON
