Hello, hope I'm in the correct forum, recently I've bought some new ball in .457 and .535 the ROA balls are perfectly round and unmarked and nearly equal wieght but the 54's are 7 to 8 thou out of round and can vary in wieght a good deal.
I have matched weighed and re rolled between glass sheets making them rounder indeed and producing 3/4 to 1 1/2" groups at 50 metres out of my GPR.
Has anyone any ideas on how to make the ball rounder ? :hmm:
