So I'm new to reloading, yeah I know bad time to start with all the shortages. Working with what I got on hand. Trying to re load Winchester AA hulls to factory specification using the recipe on the bottle of Winchester super handicap powder, one of the two powders I got on hand and my MEC 600 Jr. According to the MEC bushing chart they do not have one that throws the exact 20.7 grns that the recipe calls for so I got #21 and #22 since these are supposed to be right around 20 grains. Figure I'd measure each time and discard a little if need be for safety. However the #21 is throwing about 16 and the #22 about 17.5 according to my rinky dink Lee scale with the little ball that you roll back and fourth. For shoots and ladders sake I tried a #30 bushing that I bought for ramshot competition and it throws 23 grns exactly of the win handicap stuff. Is that scale no good? Does MEC not know their own bushings? Or is the Winchester super handicap just a pain to work with? Should I get a digital?
Welcome to reloading! Now's a great time to start, just different than if you'd have started 20 years ago..
Keep asking questions, that's how you learn:
First, "Is the Lee Safety Scale any good?" Yes.
Second, "Is that scale no good?" The scale is as good as the operator.
Third, "Does MEC not know their own bushings?" They probably do. But also developed their data under a certain set of conditions, your conditions may be different.
Forth, "Is ____ a pain to work with?" Most all reloading steps/processes are finicky, depends on your threshold for pain...
Fifth, "Should I get a digital?" Of course - if you want one.
All measurement devices have pro's and con's, features and limitations. The issues between them are different (breeze from HVAC, EMF, florescent lights, etc..) but they both have issues. Just know what you're working with and make accommodations accordingly.
