I've the rossi puma in 44 magnum, with the octagonal barrel.
Touch wood it's never skipped a beat, it my favourite rifle by far and have put a fair few hundred rounds through it.
Good luck chap
That's a decent number that, good effort chap.
Have you bought a pole or have you diy'd one.
Always wondered if you could get screw ends to put on pole from somewhere and make your own.
