Well I FINALLY got the completed rifle home this weekend, loaded a few break in rounds and some OCW loads last night.
Got a chance to go out after dinner this evening as we had little to no wind so it was ideal for a little break in and test.
I opted for 2 x Shoot 2 & Clean instead of my usual 3 x Shoot 1 & Clean, 2 x Shoot 3 and clean, etc....
The first 2 rounds from the Broughton took me awhile to clean as the copper left behind was quite substantial, picture blue baby snot once the 26% Amonia hit it

.
2nd bout of 2 rounds went much easier and cleanup after the 5 shot group pictured below was an absolute breeze with very little copper fouling showing up on the patches.
As you can tell by the picture below this gun certainly looks like it wants to shoot.
My break in was done with some old 180 Berger VLD Match bullets I had in the cupboard with a powder load that fellow shooter recommended for fireforming loads.
The 4 foulers were my start load for the OCW using 180 Berger Hybrids
Pics of the completed rifle to come in the next few days.
