Hi Ed,
Thanks for the reply, that's quite interesting I had a sneaky feeling having had an Airsporter back in the 70's that it would be better with a lighter pellet and possibly a slightly bigger skirt. My old 0.22 Airsporter was way better with the 5.6mm Wasp pellets than the 5.5mm version. I think I'm right in saying older BSA barrels were slightly bigger than later ones / European ones.
Thank you for your kind offer of the pellets, I'll hold off for the time being, Mark who I bought the gun off gave me a quantity of RWS Superdomes (8.3gn) that he'd been using for Bell Target competitions, these seem ok, and I also tried my usual JSB's but the skirt must be smaller ( 4.52's ) as they drop straight in
I saw the ms025 spring on the Chambers site listed under the BSA section "Standard" funny thing is on the improved model D listing they quote a std spring pair, light version and a 0.22 version then a 0.25 one ! No mention at all of 0.177 ?
I think I saw somewhere that the model D in 0.177 is rarer is this right ( saw it quoted as only 1 in 10 made were 0.177 compared to 0.22 )
The very least I'll do is get a new piston seal for it.
Many thanks,
Norm
