Awhile back a year ago I posted up my new trap that I had made out of 1/4” welded up plate. Has worked great, and it doesn’t matter what distance. Wether 36” away shooting thru a chronograph or 50 yards away, my 30 cal pellets land on them like flies on a windshield at freeway speeds. But, I have to say, it is heavy with an additional 8 lbs of duct seal.
My much lighter version which was a NEMA type 1 electrical junction box at 10” x 10” was way lighter, but the 16 ga steel was easily phased by the 30 and 25 caliber pellets, if you were first sighting in a freshly mounted scope.
After a year of using a hand truck to haul my trap out to 50 yards, I told myself I needed a lighter version.
So back to the electrical box box I went, but this time what I did different was line the inside backside with 3/16” plate, bolted up, then cover the face of the electrical box with a 1/4” plate picture frame, to protect the face of the trap. Way, way lighter by about 15 lbs. So, this will be my haul out to 50 yards trap, while the heavy one can be for chronograph use. The electrical box doesn’t work to well shooting thru a chrony 3’ away cause of its lighter weight, I need to clamp it to the table as the shots keep driving it backwards. The heavy all 1/4” plate one I don’t need to clamp down. It hardly budged with a 30 cal shooting 876 FPS at 36” away.
