BSA supersport Transfer port modifocations

[evert]

I wasn't thinking of power limits, I was thinking of the amount of preload and the port size, together making it a bit slammy...

I shoot FAC springers too, and have a pro elite that shoots softer than plenty of 12FP springers I've fired.. whilst ticking over at 20 FP. Incredibly accurate too...

Yeah, it feels a bit too much now. But it is still recoils quite flat, and seems to have less tendency to vibrate than the 3,2mm port.
The .177 XL Lightning with the same spring/guide setup is softer, but I'll have to set up another Supersport with the same spring to do a side by side comparison.
