Dear friends,

I have a .577 3" BP Express double rifle. Does anyone have an idea if nitro proofing would be an option? I have heard that besides the difference in pressure there is a problem with regulating the rifle and there is supposed to be different twists of the bores.
If not, what would be a practical hunting load? Would it be an option to us Pirodex f.e? I cannot find loads for this round in the Pirodex data.

With kind regards,

Huub
