You did resize them before you trimmed them didn't you? I ask because it looks like you are depriving in the press and that would tell me they have not been sized.

I have the same case trimmer. I made the operation a lot easier and faster by removing the handle and replacing it with a 3/8" variable speed electric drill. To prevent placing an undue strain on the trimmer I planed a section of 2"x4" to the right thickness to support the drill. Works like a charm and no more sore elbow.
The very first step I take in reloading is to punch the primers out with a special anvil and punch I have made up.
How many times has this brass been fired? It being M1 carbine and a short range caliber IMO it's a waste of time unless it has been fired several times and you are concerned about safety factors
Trimming is very important with the .30 carbine as it headspaces on the mouth of the case.
If once fired how big a factor is OAL? I admit to never reloading the caliber as it does not interest me..
Mark, thanks for the clarification.. if you miked them and they were that different in OAL then it makes sense
The biggest OAL issue with any magazine fed weapon is that the round isn't too long for the mag. The next issue is that the ogive isn't too far forward that it engages the rifling before the bolt is fully in battery.
Well as said the 30M head spaces on the front edge of the case so its way more important then most other semi autos.
