No I didn't Tony. I wanted the MV average and SD straight away. My next tests will be strictly as per "the system".

My goal with these tests was mainly to find out where my 2900 - 2920 node is now as my barrel has sped up so much since I first developed it. I'm now more than 3 full grains of ar2213sc under the original charge for the same speed. I also wanted to get some more rounds through it to try and get the speed to settle. I think it has now.
I shot an educated guessed load of 64.0gn at 300m today and had a good result.
Now that I've identified where my node is, I'll follow the system strictly as you'll see in our FB group.

Looks like good waterline Denis! It will be interesting how it holds up at longer ranges !

I believe this nodes a trough Graham and proper testing will reveal whether 64.2 is positively compensating as I think it might be. If it is I'll try and find a second load for 8,9 & 10.
