How many rounds for load development?

[PiratePast40]

How did that 25g of H335 do for you?

Very little difference between the 25 and 25.3 grain loads in accuracy and both were really tight groups at 25 yards. It was overcast and sprinkling so the chrono readings couldn't be trusted. Tried CFE 223 at 26, 26.5, and 27 grains. 26 grain had the tightest group. None of my loads with either powders showed any overpressure signs. Interestingly, one of the American Eagle rounds actually had a slight ejector discoloring/mark on the case head.

I make 5 rounds per charge, start near the middle of the load spectrum and in .2 increments to max.
I also write the charge amount on the case itself that way I can check primers for overpressure.

I color code the primer or cartridge base and keep that in my notes

You need to start a go fund me page for targets.

Just kidding.

Are you a telephone guy?
blue orange green brown slate-white red black yellow Violet.

Show me 25 color combinations that make the telephone world go round.

No, I don't have 25 different pens, let alone 5! But I'm never shooting so many that I can't get by with 3, coloring either just the primer or the whole case head.

Start with the white wire (tip) and start with the blue wire (ring)
pair 1 = white blue
pair 2 = white orange
pair 3 = white green
pair 4 = white brown
pair 5 is white slate
Progress to the red wire and start with blue wire
pair 6 is red blue
pair 7 is red orange
pair 8 is red green
pair 9 is red brown
pair 10 is red slate
Progress to the black wire and start with the blue wire
pair 11 is black blue
And so on, it's pretty easy to learn but it took me 3 months to get it in my brain.
