It's academic when you don't know the length of line used to fill the cylinder. We also don't shoot at a fixed temp... i think last year I covered 35 degrees.

I don't think anyone is going to get upset about the fill count not meeting x person's predictions... the benefits of 300 are that if your shooting at 200 bar you can hold a lot more air in the same volume for a longer amount of fills.

Reminds me... I need to get my 3L filled... i've forgotten how many fills it's done... but it's down to 185 and i'm scrounging air. Even though I shoot almost every weekend, and regularly each week, I can't for the life of me remember how many fills I get out of my 4 pcps... all with different sized cylinders.
