3" chamber
 

My friend bouight a Stoeger Commanche that is chambered in 3" for both barrels, he got 2 the 12 and 20 gauge,. He is trying to tell me that he can shoot 2 3/4" shells in it. I have shown him my browning and stevens where it says either or 2 3/4" or 3". He says it makes no difference if it can shoot 3 it can shoot 2 3/4". I dont think this is correct and would hate to see him blow himself up, he owes me money. If i am wrong then i stand corrected but he has promised me that he will wait to shoot it until i get an answer. thanks in advance

I shoot 2 3/4, 3 and 3 1/2 inch in my 835.

My model 12 shoots either 2 3/4 of 3 inch with no problem.

The 3 inch stamping on the barrel just lets you know that it will take up to 3 inch but you can still shoot 2 3/4".

I agree my 20 guage H&R is labeled 3" and I have been shooting 3", 2 3/4", and 2 1/2" for 28 years come this December.

You can go down a shell size, but you can NEVER go over the shell size.

The labeling '3 inch' or '2 3/4 inch' is telling you the maximum length shell you can use in a given chamber- not necessarily the only size.
In the case in question, 3 inch is the maximum length shell you can use. As the others have said, you can also use 2 3/4 shells in a 3 inch chamber.

thanks everyone
