Again if you go you will at least need one more person with you and even on some weekdays it can get busy. So if you go prepare to have to wait for 1 or 2 hours before its your turn to use the range.

They have a selection of rifles (nothing larger than .223), pistols and shotguns that you can use, and no need for a PAL.
