How much variation in powder charge from round to round can occur and still maintain accuracy? (Assume: non-maximum charges for safety reasons).

I've been using extruded powders in my rifles forever. Always trickled charges to weight after coming out of the Uniflow. Now I've been thinking: what variation in charge weight (average and extreme spread) could be expected by using a ball powder and not weighing/trickling each charge? And how much larger would my groups get?

I know not to expect the same match quality. Maybe good enough for pratice though. Any ideas or data.

Thanks.
