FAS 6004

After eventually finding the seals that my wife had opened, put down, covered in junk mail and forgot about, I excitedly fitted them to the Supertarget. 
Naff-all improvement.
Maybe another 10 or 20 fps after I re-set the barrel to account for the slightly slimmer breech seal.
So with every possible modification done, (apart from drilling out the transfer port to 4mm), I am seeing 350/360 fps with 7.33 grain H&N pellets.
But today I got over 425 fps with a lead pellet I hadn't tried in it before!
The 'awesome' Kvintnor Delta Russian ammunition!
Super-fast but absolutely abismal accuracy. Even at a distance of 8 feet from the target, the spread was about an inch.
Speed isn't everything...

Been down to the end of the garden to give the Sig a better try out. Still getting used to handling it now I have finished tinkering with its innards.
I think I have found that Meisterkugeln or R10 pellets suit it better than the H&N Econ II, but I have yet to find a gun that suits the Kvintnor Delta.

360 Fps is about what you can normally expect from these once correctly sealed. So at least you have achieved correct sealing.
The rest comes from piston packing but can be fraught with technical challenge to get it done right.
H&N Finale lights are the best i have encountered in Chiappa barrels.
