Yet Another Shotshell Reloading Question

[Duffy]

Please pardon yet another shotshell reloading question, but you guys are very helpful. Is it typical for the MEC 600 Jr to drop a shot load slightly underweight than the charge bar is rated for? The charge bar on mine is rated for 1 1/8 oz loads, but it is dropping just a smidgen over 1 oz, but not quite 1 1/8 oz. Has anyone else experienced that? Any problems? I assume it does not matter, but I wanted to check.

I have also read that bushings will typically throw charges under what they are supposed to according to the charts, such that you may need to go to a bigger bushing to achieve a charge closer to what any recipe may prescribe, and I have already had to do that.

Thanks in advance for your answers, as ever.
