Shifting the thread. Good luck with the build.

I looked to have a .577 LNE build on a Greener Empire E17 shotgun in 12-bore. Rolf Babnick built Marrakai's short barrelled "Fat Lady", which is now Mick's/264's. Of course then I needed a second shotgun so I could have a DR AND 12-bore barrel set.

Ralf told me he doesn't build them anymore, too much liability, and he claimed similar cost.

For a gunsmith I understand the first. Someone blows off half their face ... Perhaps overloads, plug in barrel, or make?

Cost the same? Doubt that. A modern .577 dr is usually quite expensive, more than say a .470.

Myself I wouldnt dream of doing it myself lacking the skills.

So I have a nice old Greener Empire in 12-bore for fox and duck shoots.

Actually I think a .577 Light Nitro Express would be nicer with external hammers.

So what cartridge chambering?

My choice with zero info on the donor shotgun, is the .577 2 3/4" Light NE.
