Well I own one of the Circut Judge's in .45 colt/.410. Right off the bat I thought it was ok accurate. But its not. With a load of 8.5gr of Unique and a 250 gr jfn (which is very accurate out of my 5.5" blackhawk) it PRINTS 4 to 5 inches to eather side of the bull at 50 yds. I am pretty sure its that BIG jump to the barrel from that LONG .410 chambered cylinder. I may slug the bore to see if its bigger than .452. Has anyone who owns one of these tried a longer COL to make that extra distance through the cylinder a little shorter. The other issue with these is cracking of the buttstock at the tang. When I received mine I noticed play / looseness with the buttstock. This may be an issue on others causing the cracking if you dont tighten them up. I tightened mine up and with 250+ rds out the barrel the buttstock is ok with no sign of cracking.The trigger seems to get alot better the more you shoot it. Other than that stuff its a hoot to shoot ! Practical its not but fun it is.
