I managed to scrape up some shooting supplies for the .54 cal Knight Black Knight rifle I got on an auction a couple weeks ago and took it out today just to get the scope close.
At my local shop there was one old pack of T/C .54/.45 sabots. These were so old the clear plastic packaging was yellowing from the gas heater in the shop. And I had some 300 gr Sierra soft point .451" bullets.
Off to the range the first two shots were only 3" low and about 1" left and were touching @ 25 yds.
Made some adjustments and moved the target out to 75 yds. (that was my max range at this area). After some more scope adjustments I settled in and shot a 3 shot group measuring about 1 1/2". Not real good but I wasn't too upset. I got this .54 to shoot big old conicals not saboted bullets. If I want to shoot saboted bullets I'll stick with the .50.
The sabot/bullet combo seemed to load with a nice even pressure but when I walked downrange I noticed that every sabot I picked up had at least one of the petals off. They must have gotten brittle with age and could have been affecting accuracy?????
Heading to Cabelas tomorrow to get some conicals for it.
