You have a good site just down the road from you.
Fireball Squadron at Bassets Pole. It's a good site, Think the rentals are M4's.
The site is at the back of the paintball site by the Mcdonalds on the Bassets Pole roundabout. You have to drive through the paintball site, down a mud road for quite a distance then you get to the car park and game hut.
Because of the location once on the site you can not get off it again until after the paintball site has finished playing. Unless it is a real emergency.
They have coffee/tea/soft drinks, and a selection of sandwiches at lunch for a reasonable price.
They have BB's for sale and some very limited stock.
The site itself is dense woodland. With a good collection of buildings/structures. The density of the woodland is such that you very often engage at CQB ranges.
Games days are the first saturday of the month, and they like you to pre-book if using hire guns.
They also like you to be onsite early. You have to be on before the paintball site closes the gates. So it is best to be slightly early, grab a cofee in Mcdonalds and wait for the gates to open. All the information you need is on the website, but it would be worth calling them if you are planning on going.
Boots are also required at the site as a site rule, And you will need them. There are rabbit holes, exposed roots, and brambles.

Next shoot there will be on the 7th July.
Not sure if I'll be there as I've only made one this year so far! Everything seems to happen on a saturday atm! The regulars are a good bunch, chatty and normally fairly friendly.
