As
@Sash says, plus
Membership of the biggest Home Office approved club
£10million liability cover for pretty much all shooting, including pest control, and even beating/picking up. Satisfies the owners of my permissions so I don't need separate CCC or BASC cover.
£10,000 insurance cover for your own shooting kit
A wide range of firearms to hire from the Armoury, at very modest prices, for example half day hire of a scoped Accuracy International £31.50, or a straight pull L1A1 for £18.00, and you don't even have to clean it after use.

NRA Shooting Club, usually 2 days a month, can shoot multiple firearms at multiple, (usually 3 or 4) distances in a half day session. I've done 25yds, 200yds, 600yds & 1,000yds in one morning session.
Guest days, bring up to 4 friends to have a go, with free loan of some of the NRA firearms, just add ammunition. Scoped Savage 12 FTR in .308, straight pull AR-15 in .223/5.56, SMLE in .303Brit. Plus you can bring your own for them to have a go with as well.
Sizeable discount on annual membership of the National Clay Shooting Centre at Bisley, £80 instead of £140
If you are within a reasonable travelling distance, a great option that I feel gives me great value.
