Wanted, Diana 34/52 cast metal trigger guard

[maximus]

Got it back together the other day and it is now lovely and quiet to shoot, no twang at all but it's only doing 9,5ft lbs. I suspect the breech o ring may not be sealing properly or the piston is a bit tight so further tinkering required. I will start with the breech seal.

Edit, swapped the breech seal and now doing 591 fps with falcon accuracy plus equating to approximately 10.5 ft lbs. Happy with that for now, will do some open sight plinking and see how it goes.

That's healthier! Should be sweet at that level but similarly near the limit as they are quite pokey guns. Slightly more stroke on these than the 34 I think and careful sizing of the piston seal will release more if needed as you know.
Happy shooting
