Vinny thanks a lot,
that's a lot of good advice there. I set it up a few weeks earlier in Atherton indoor range, on Sunday 7th it shot really well, then this Sunday, I thought it needed a tweak on the turrets whilst on the plinking range, so back to Atherton as soon as I can get there.
Up until now, it has been fantastic, but it does get heavy in the positionals, especially kneeling.
I will let you know what I do and how it goes as and when.
Once again many thanks for providing so much help,
