Ok, let me start by saying i know nothing about shotgun slugs. I went into the gun shop the other day to get my usual box of 00/SG buckshot to shoot pigs with. While i was in there i asked him about slugs and how would they perform on pigs, he said they would be worth a go and he gave me a box of 25 slugs which have no markings on it to tell me what kind they are. My question is, what will the recoil difference be between the 00 buckshot and the slugs or compared to a rifle caliber?
Sorry i cant give you more details on what type the slugs are.

thankz
