Editing Shotgun slug (section)

===Design considerations===
The mass of a shotgun slug is kept within [[SAAMI]] pressure limits for shot loads in any given shotgun shell load design. Slugs are designed to pass safely through open chokes and should never be fired through tight or unknown barrels. The internal pressure of the shotshell load will actually be slightly higher than the equivalent mass slug projectile load, due to an increased resistance that occurs from a phenomenon known as shot setback. Common 12 gauge slug masses are {{frac|7|8}} oz ({{convert|383|gr|g|abbr=on}}, 1 oz ({{convert|437.5|gr|g|abbr=on}}, and {{frac|1|1|8}} oz ({{convert|492|gr|g|abbr=on}}, the same weight as common birdshot payloads.<ref>{{Cite web |title=Home USA {{!}} Brenneke - Ammunition |url=https://www.brennekeusa.com/ |access-date=2022-12-26 |website=www.brennekeusa.com}}</ref><ref>{{Cite web |title=Shotshell Ammo {{!}} Winchester Ammunition |url=https://winchester.com/en/Products/Ammunition/Shotshell |access-date=2022-12-26 |website=winchester.com |language=en}}</ref>
