I’m more of the , I get the bushing by the table that’s supposed to drop what I want and I load . I’m meticulous loading rifle cartridges not as much so with shotgun shells .

You would probably be surprised if you weighed your drops, especially from MEC bushings, they're notorious for drops different from those published on the charts.

I have weighed some in the past and you are correct . But it’s not just the Rube Goldberg MEC’s I saw the same thing with PW bushings in the 800C’s I used when I first started loading . But the bottom line is “usually” that small amount by charge isn’t going to make a difference . Now with that being said there’s nothing wrong with drop weigh drop weigh drop weigh I just don’t care to do that anymore . As I said before I still weigh rifle charges but generally I’ll never load more than twenty of a specific load at a sitting . Years past I went so far as weighing new empty rifle cases and segregate them by every five grains but that was far so called bench rifles . But to each his own , my intrest in getting to in depth anymore is leaving me from what it once was .

I know I will get some flak for this but the best investments I've ever made to upgrade my MEC's were the adjustable charge bars that were made in Canada. I got tired of messing with bushings a long time ago.

Powder baffles do help. I always throw about 5 or 6 "dry run" charges after filling the powder hopper. Then I'll weigh a couple just for my piece of mind. I am also in the habit of recording the powder charge weight and type on a small rolled paper and sticking it the hopper, easy to read and a safety check for interrupted loading sessions....dogs, wives, phone, or just ready to go sit down!
