Shotgun ammunition in the UK is defined as being 5 pellets per cartridge or more, any less & it requires an FAC to possess, BB are 4.5mm in diameter & there are approx 70 pellets per ounce.Briggs 2.0 wrote:@ForgeCorvus
I'm going to stand to be corrected here but I am 99% certain that SGC limits shot size to BB.
SG & LG pellets or as the Americans call them 00 & 000 Buckshot are 8.3mm & 9.1mm respectively.
SG (00) usually have 9 pellets per cartridge but some like those made by sellier & bellot can be found with 12.
LG (000) typicaly hold just 6 pellets, both SG & LG are legal on shotgun certificate within the UK.
Gamebore "Buffalo" are a good brand of SG (00) buckshot available in the UK as they have the gordons recoil reducing system & pattern quite well, but not as good as the Federal Flite Control which employ a special wad that holds the shot pattern together for longer, giving a much improved pattern on target with a reduced "doughnut" effect over far greater ranges.
The federal flite control rounds are hard, if not almost impossible, to find here but can be brought back from the USA if you ever get the opportunity to visit.
These heavier loads must be treated with a greater respect & are deadly at much greater ranges than regular birdsot ammunition & care should be given to ensure a suitable backstop when using them.
