Bullshot,
It is awkward off the bench, indeed. I shot my Aydt for the first time a few days ago with Lee 180 grain gas check 8 mm (0.323") boolits and it shot reasonably well, although nothing to write home about. They were made to shoot off-hand, so I am going to cut a 4X4 and clamp it to the metal post of the cover over the benches at the range so I can rest the barrel on it and shoot off-hand. I can't shoot for sour apples off-hand without a rest!
