Ok thankyou chaps very good.....

Personally, I have Kynamco in mind for these guns. Sure its dear, but this would never be a 'daily popper' for me at all.

-My question was based upon the risk that the previous owner had been putting the gun through too much stress, or that it was made for a heavy load.

Do 577 loads differ? it seems so....regulated for lighter or heavier loads, no? Can the old guns use loads such as Marrakai's Greener conversion??

Thankyou!

Ben
