Here's the results from today's experimentation. Targets set out at 121 yards with a 7mph 45 degree crosswind. All shots were 5 shot groups:
Powder weights from 25.2 - 25.6gr
COAL adjustment using 25.1gr which I figured had the best potential following yesterday's results.
Think I'll stick with 25.1gr with a COAL of 2.290". I'm confident what little vertical stringing there was, was in fact down to me. It would've been helpful to have a finer dot to use as an aimpoint.

I'm sure this is a daft question but you are cleaning the rifle thoroughly after each session (not group) and not just using a pull through or some such?
Are you using the rifle for target or foxes? If foxes then all those shot today will kill it.
might be a daft question but if you have used the n133 with success, why switch to another powder.....ive just done my 53`s with n133. >HERE<

Have you tried vit 140, I use it in .223 and get very tight groups, it also meters very well
For what its worth my best 5 shot group at 50 metres was 0.22 inches that was using 24.0 gn of vit140 behind a 69 gn sierra match king.
I have had similar results with cfe 223 same load and head.
