I would like to replace the powder so that I can do a load work-up using TAC without using my valuable stash of boxer primed brass. Plus I am sure I could make much more consistent charges than the surplus stuff anyway.

I understand your point,however you may find that after working up a load with TAC or any other powder in the berdan primed case that it may shoot differently to point of aim when that load is used in a different case and boxer primer.
Nothing wrong with working up a load with the original powder. Just pull and measure a random number of cases in the same lot number and measure the charge weights. I generally start with a load at 2.0 grs. below the smallest charge weight measured and work up an accurate load from there. European ammo is loaded to C.I.P standard which is generally at a slightly higher pressure than SAAMI standards.
I've done this many times with brass case mid 50's Bulgarian 54r ammo and found that doing so gave more consistent and accurate ammo.
