I have been thinking about getting one , since learning about them.. a few months after the reloading started. Has not even been a year yet of doing it. However, right before early deer season , muzzleloader started I took my new flintlock deerstalker 54 cal to the range to learn how to shoot it. Sight it in and just get familiar with , Tuesday ,season started Saturday . Anyway I met a gentleman there, John, at the rifle range( a min drive down the driveway from the pistol range at the club) 357 sig shooting it thru his chronograph. Competition I believe was the make. I left him alone till he was done with his set. Then inquired. Turned out he retired from where i work , I know 3 of his 4 children and we knew a lot of the same people. He told me he had been shooting competition for years , with his boys. Reloading 30+ years, etc. Bought one 10 years ago and wondered why he took so long to do it. Said it helped with load development. And safety overall. Anything can fail he said, even after you just checked that scale ,calibrate it ... anything can happen he said. Told me about a guy Kenny who worked there as well, (he sponsored me joining the club when I moved & started working there) Kenny was ....we will say different but he is a nice guy. He was trying out new loads.. well John said he must have ran it over with trickler... said Kenny always loaded em hot! Told his boys get back when he shoots. They all did that day.. Kennys gun blew up into hundreds of pieces he said. Very Lucky! his hands has some burns was it. Safety glasses were on. I stayed , kept shooting, John left after we talked a bit. Neil , a gentleman a see at the range often. He showed not too long after. Set his up Caldwell. 222 Remington loads he was working on. Groups looked damn good. Said would not believe just how different the numbers vary from the data books. And he is correct, like i have seen posted on here already. Same barrel length ,chamber etc.. I do plan on getting one .. just which is the debate.. would like one for all 3 shotgun , pistol , rifle
