I have been reloading for .223 with AA230 only so far with 55gr FMJ bullets.
When I was working up what load my rifle liked I did 10 rds of AA230 at various powder levels.
I did 22.5 to 24.7gr in increments of .2grs
My rifle liked 23.2gr the best.
This was the first time reloading for .223.
What I don't recall/have data notes on was the trim to lenght. I know I checked each of the cases (once fired commerical brass used in my AR-15) to ensure it was below the MAX of 1.760 and tried to get them as close to 1.750 but the brass was ranging from 1.755 to 1.748 IIRC.
Now I plan on using H335 and again will be 10 rds at various powder levels.
However here is where I'm not sure which way to go/if it matters.
I have a batch of brass (range pick up) that is all at 1.750 already, trim to lenght.
I also have a batch of brass (the same brass from before; this would be the 3rd time fired, 2nd time reloaded) but it ranges from 1.755 to 1.749, trim to lenght. Its only been fired from my ar.
So would which brass would you use and why?
This is for plinking Project Appleseed targets on the 25 and 100 yard ranges.
I only have enough H335 to do this test once for now.
In the end when I reload again for this AR so long as the brass is under the max and above the min I will load for it based on what I find here today either with aa2230 or h335. For that reason I'm thinking go with the 3rd time fired brass. However, the compolusive part of me says remove the trim to lenght variable from the equation to know which powder level is best (granted not all the brass is from the same maker so their might be slight differences and thus why i wanted to use the 3rd time fired brass which is all from the same maker and has only been thru my rifle.
So which way would you go?
