chamber lengths

[pete evans]

i have always been under the impression that a 2 3/4" shell shot from a 3" chamber doesnt pattern as well or have the same velocity as a 2 3/4" shell shot from a 2 3/4" chamber. Now i know that a 3" from a 2 3/4" is dangerous pressure wise and shouldnt be done.

in the shooting press i notice that most guns are chambered 3". does this mean that people compromise their gun performance for the occasional time when they use 3" shells or have i been misinformed all these years?

No they dont compromise at all , a lot of people have the forcing cones lengthend on 2-3/4" chambers for reduced recoil (note:- mainly target shooters).

 

but if your shooting a 2-3/4" from a 3" chamber , same thing .

the pattern from the load is affected by the barrel constriction to choke diameters ,not your chamber .

 

and your right, big nono with the 3" in 2-3/4 chambers ,the pressure increase is obviously relative to the load fired ,but still "WAY TO HIGH " JUST DONT DO IT ,you may end up wearing a receiver for face decoration .
