I had heard somewhere about using 54 cal 60 gr pellets in a 50 cal gun, so I tried it today at the rangewith great success. I had been shooting 130 gr (2-50 gr 1-30 gr) of Pyrodex, but 120 grs worked great. Iwas shooting a Knight Disc rifle with a 24" barrel topped with a Zeiss Conquest 4.5-14 scope and a 250 gr Barnes Expander. I shot at 50 yards and 100 yards. I "clover leafed" at 50, but I pulled one shot at 100 about an inch low. Both groups were with in 1 1/2" across. I shot my 130 gr load also and got basically the same groups. I will probably continue to use the 54 cal pellets, so I don't have to carry two sizes of pellets. Just thought someone might be interested.
Do you own a rifle with an easy loading QLA System. That would be the only way I know to stuff a 54 caliberpellet in a 50 caliber muzzle hole.
