Hi Stuart
That rifle is very impressive indeed. I noted you mention the 1:7.5 barrel twist, is that something new? I thought everyone was running a 1:8 twist for the 6mm and variants, but I am just leaning and maybe you have found better bullet stability with the higher twist. It may also allow you to run a heavies bullet then a 105, would like to hear your thoughts on it.
Turners - I have tried 4 or 5 different types on Rimfire rifles including Harrels, Loweys, and Huntsman using the "Purdy" tuning method. I have never found them to be beneficial and just feel I wasted time and ammo trying to Tune. Others swear by them and others add tubes to the end of the tuner in the hope of find a winning combination.
On my FWB 2700 (Feinwerbau) I just put on the factory bloop tube and then gun shoots very well, it was the rifle used by Tony Ryan who came 3rd and shot his screamer patch. Ed McGrann shot it at Wagga and also finished 3rd and shot the highest scoring target - neither shoot had every shot the rifle before the match!
Kathy's rifle has a home made tunner which has never been adjusted, just sits there! The rifle has a Hall action which is very light and easy to use and a Broughton 4c barrel which must be a hummer as its won many events.
Most important, the tuner gets a lot of crap build up over time and should be removed and cleaned separately. Good time to clean the rifle crown as well.
