45flint : no apologies necessary, it's always nice to see a good looking elegant rifle on the forum!

JOHN K : I have a couple of GS397's, one resealed by Lawrie in 2014 and the other by Ped in 2018.

I've never had the power checked but I doubt it would be all that high, even with heavy pellets on a warm day -- probably on a par with the Sheridan 8/9 ft lbs.
