Stoeger is a Turkish made semi- auto shotgun. It is based on benelli's inertia system which has proven to be extremely reliable in harsh hunting conditions. As opposed to a gas systems which use gases from the firing of the shotgun to cycle the action, the inertia systm uses the recoil and the actual force from the discharged shell to cycle it. Since there are no gases escaping or being used they are known for being extremely "clean" guns. Meaning they can go long periods without cleaning. Some people feel there is more felt recoil than in a gas gun but trade that off for the reliability. Similar guns are the benelli m2 and franchi I12. Both are considerabley more expensive and made in Italy.
A pump-action shotgun typically fires one round per pull of the trigger, and the rate of fire largely depends on the shooter's ability to cycle the action quickly. Most experienced users can achieve a rate of about 3 to 5 rounds per minute, though this can vary based on individual skill and the specific model of the shotgun. Unlike semi-automatic shotguns, pump-action shotguns require manual operation to chamber each round.

A Western Field Mod 30 is a Savage Mod 520 Model 30 (based on Stevens/Savage 520) was a pump action shotgun and came in 12 and 16 gauge, but NOT 20 gauge or .410 gauge. Model 30 (based on Kessler model 30C) was a bolt action shotgun and also only came in 12 and 16 gauge. There is some confusion about model 30 Western Fields because there were two very different variations, both pump and bolt action types. If your Western Field shotgun only has "model 30" stamped on it, with no other alpha-numeric designation such as 25EKN or SB526, then it is likely a pump action 12 gauge.
