Rookie semi auto shotty question, and I got my information from old remembered processes.
If this already has been discussed, my apologies.
I did type some various search titles trying to find this specific topic... and came up empty.
I checked the 1301 Beretta Factory manual and came up short.
This 1301 is my very first brand new to me semi auto shotty.
I recall reading in the yearsssss past that a new semi auto should be shot with heavy loads for a period or it will never cycle light loads reliably.
I got some 30 years + behind an 870, had a Benelli M4 for a spell many moons ago but before I shoot this 1301, I want to start off right.
Is that still the case?
I have some reduced loads buck and slug but I can also access some with some oooomppph.
Some years back at a place where I work.... someone ordered a case of 3" loads... and it still sitting around.
