Please Note: Not all shotguns are the same! While most shotgun are capable of handling high pressure rounds such as the. On the other hand some are not. Therefore only use these rounds in shotguns that are capable. For example, a shotgun with a SB1 or Sb2 reciever. I recommend on any shotgun to test the first shot in a vice while out of harms way in addition always wear eye and ear protection. After that if you see that the primer punctured in the round discontinue using this round and use the less powerful round. Such as a 38 Special instead of the 357 Mag These high pressure rounds include: 45-70 gov., 357 Mag, 327 Shotgun Adapters , 44 Mag, 30-30 Win and 22 Hornet. Please always be safe and aware.
