Hi

Well,just cant find any stats on it.......is it a more potent round than the 577x3,or very very similar?

I found the nitro round yes,and its for sale.....same gun as your friend isnt it 500nitro? for sale as a '577x31/4 magnum' and cordite load.

Seems impossible to find the 577x3 1/4 BP data,or any gun mentioned either....was it a flop?

Thanks

Ben
