Thanks for the response. I manly hunt with it and just want to get it as accurate ax possible. To bd honest if I am not going to get Lille improvement I will probably leave it until it needs a service and then look at the options.

I have just sold a pcp and am now in springer only mode. A pro sport and a walther lgv both in 177. I probably wont bother with a pcp again as they are a bit tedious and both springers shoot so well.
Any thoughts on tuning a pro sport? It shoots very nicely but could it be better?
