Perhaps...

but hasn't prevented my Walther LG400 being modded to 16J...by a top UK gunsmith...in fact, I ordered 2 X LG400s, and the other was modded by a 2nd other top UK engineering bloke. ( one is mine, the other his).

I suppose what I'm saying, there is plenty of talent in the UK in overcoming any issue...

Regarding other 10m rifles...matter of fact, Daniel Roemer from Tesro told me at IWA...there are possible ways of power modding the RS100...so that's another one being added to my collection with a power mod.

So methinks, the Fwb 800 may be a challenge, but will be overcome with British Engineering ingenuity.

As far as Anschutz 8002, 9003, well, it's well known these are 10m successfully power modded to 12 ft/lb, and being used on FT circuit.

Will keep you posted. If the Fwb 800 prove impossible to power mod., will keep it as a wall display ornament
