Ive was given half a box of semi magnum 20g cartridges think they 30 or 32grm 4s..it reads 1050 max on the cartridge itself i was wondering what those barrels are tested to on the armsan a620s.. and thought one of you armsan users might just know??
I bought a some of the above cartridges for my son for clays but bit to punchy for him so just going to sell them of to fund some other ones. Think theres 200 there £4.50 a box. Collection Co.durham with cert.
