Probably apple to oranges, but I've found with my 9mm and 38 special guns/loads that I get better groups by bumping up the velocities using the plated bullets compared to coated.
Coated, for me, usually group best in the lower to middle powder throw range where the plated seem to be happier in the middle to upper range. This is using fast to medium fast powders and recipes geared towards plinking/ target use.
Thanks for that... I will work them up with that in mind.
