Yes, a new light Nitro 577 would be very cool ! I Have been looking for a top lever hammerless 577 BPE for a couple of years now ,found a few ,but barrels a little long or damascus or buggered or all of the above ,also think old steel barrels won,t take a soild too well,which is needed I think for full penetration on real big stuff (Marrakai would know better than I )Have now ended up with 12b rifle Top lever hammerless 3 in 15 Lbs job ! still no solid and a lack of good bullets for 12b rifle ,and no load info is a problem now ,but a very cool rifle all the same !
