I'm based in Poole. For me the Bucc's is closer, but i'm also a member of South Dorset (weymouth) as their plinking range and courses are open every day.
Here's CSFTA's website www.csfta.co.uk
I'm the chairman so if you want to ask anything ask away. As a region we cater for FT & HFT.
There's also the club map
. Christchurch gun club is close by but it is limited in it's facilities. It's been years since i've been down there so that may have changed. Parkstone indoor club i'm a member of as it's handy for dry practice, zero'ing etc.
