G'Day Fella's,
While I'm in between doing other things, I've been running in the new barrel, on the BSA.
I initially cleaned the barrel and the prepped it with a Moly barrel treatment product, from Brownell's (as per their instructions).
I then fired the first shot of a ladder test, into my bullet trap and then cleaned the barrel........
Here's some images.
The loading block, with the 1/2 grain increasing powder charges (x2 each), and the first shot now fired.

Here is a better view of the bullet trap (250mm Dia, 9.5mm thick steel wall x 1.500mm long steel pipe, filled with "Stuff"......... to stop bullets.
Please note the flexible exhaust hose, connected up to the B/Trap.

And the rifle in it's MTM cleaning cradle, with some Patch Out, bore solvent up the barrel.

I do a Ladder Test, and run in the barrel at the same time.
Once I'm aware of what appears to be the Maximum Safe Working Load (MSWL), I then head for the range with some additional loads, around this same powder charge.
If ithe rifle shoots OK and velocities are where they should , I will settle on a powder charge, and then work on bullet seating depth, to get it shooting to it's best.
Hope that helps
D'oh!
