Cylinder bore guns sometimes shoot donut patterns if there is too much powder for the shot charge so you should pattern the gun at 10-15 yards to see what it does on a piece of butcher/freezer paper stapled to a piece of cardboard. No need to get fancy with the patterning.
A little late here, boys. Whut I got ta say may not be werth spit ennyways......
AA hull, somewhere at 50 grains Goex 2f 'n 209 Wimpchester primers. Powder, a scoop full of grits, 1/8" nitro card, a squirt of Crisco 'n 7/8 oz. of anything from 7 1/2 to 9 shot.
Them honeys ain't much to shoot, maybe a l'il bit more than FeatherLites - precious little more. Been takin' knockdowns of various manufacture down without a problem. Everything was lovely.
Hit a shoot late August. One stage was all shotgun, two Texas Stars. Clear 'em, whatever it took. End of stage.
My Coachgun, 'n I had an Uplander with tight chokes in the cart I decided not to use, didn't wanna get it dirty, is Modified and Improved. Figured I'd alternate Stars. Give 'em more of a chance to settle down. Took the top plate off the left one, left the top plate on the right one and that was the story of the stage. Had a fit with the improved barrel. Took me 16 shells to clear the things. The last four were the 'knock-'em-down-stomp-all-over-'em' 1 1/8 loads I carry for stubborn targets 'n thems a bunch worse than FeatherLites. Damned near melted the barrels down......
One ah the fellas watchin' was an ole time skeet shooter. Told me it looked ta him like I had a hole in the pattern 'n suggested a shot cup. I'd say Hellgates onta somethin' here.......
