Cheers for the advice all - all makes perfect sense
Never shot indoors before - well its only been about 3-4 months since my beginners course! hahaha

is that all ?? WOW - this must be addictive, it plagues my every thought!
You have all been the voice of reason so I will follow the advice - besides 60 yrds will be fine to shoot throughout the winter (less walking up and down the, now, freezing field!!)
I have just been doing Short Nationals up until now which currently 3rd class.
Did my first National today and got a comfortable 2nd class score - 454 - which I am chuffed to bits about
Hopefully I can grab 2 more before season ends and we all head indoors so I can get a new sticker on the 'handicap board', not to mention a badge for my quiver!!
Thanks again for the replies
Happy shooting
