Been there done that. Not sure how you got there but mine has happen(s) from over powering the case trimmer past the stop with my right arm.I inadvertently trimmed my 300 WSM brass to 2.087, min trim length is 2.090. Will I see any negative effects? Thanks guys
Someone please correct me if I'm wrong. Regarding Max, Trim, and Min case lengths, I was told that the "trim to" is Max - .010", Min is Max -.020"
Just using the 300 WSM as reference, I would have assumed:
Trim To: (2.100" - .010 ) = 2.090"
Min: (2.100" - .020) = 2.080"
And trimming below the "trim to" is fine, so long as you don't go under the Min length, and more importantly is to trim them all the same.
Please chime in and set me straight if I have it wrong.
I agree, and for a measly $6.00 for a chamber length gauge, it’s a no brainer to get them and know exactly where to trim.I will add as to why I said for the time being, if cases are trimmed too short. Meaning short term and you can let your cases grow out from there. Reason being in my mind is that you would risk a carbon deposit or ring forming out ahead of the exposed area in the neck of the chamber if you continually kept them short, then later if you switched to normal or max length cases, you could have immediate high pressure.
I will admit that I don't have a handle on exactly why or when carbon build up will show up. Seems some cartridges are more prone to it, as well as some powders are said to be worse, or bad for it. Cannot confirm that personally but doesn't mean it isn't true.
