Hello all, with help of the forum(s) i have just bought some scales (on balance ct 250, @ £36) and they are very good. I weighed about have of a tin of jsb exact 4.53, 8.44gn, and the results where as follows: 190ish @ 8.4 to 8.5 (i.e a mix of say 8.40/8.41/8.42/8.43/8.44 & so on up to 8.50) and about 20x 8.30 to 8.39, - 20x 8.50 to 8.59, - 10 x 8.60 to 8.69, and a couple of 8.2's. Anyway my question is, what deviation in grain weight terms, would affect the accuracy of a decent regulated rifle? By this i mean, randomly loading one of the lightest pellets from the tin 8.2/3gn and then the heaviest @ 8.6+gn? thanks m
