3" vs 2-3/4" CHAMBERS

Dear Technoid,

Can you tell me why the Cynergy Sporting model only comes in 3 in
chamber?

i want the looks of the Sporting with the punch of the 3 in....and a
ported barrel..

any ideas?

thank you for your time

Richard





Dear Richard,

What you meant to say was that the Cynergy Sporting comes only in 2-3/4"
chambers and you'd like 3", right?

Well, the reason is that Browning thinks that it gets better patterns
from 2-3/4" shells when they are used in 2-3/4" chambers, not 3"
chambers. Some time ago the Browning website had a FAQ that addressed
that point and gave Brownings test results comparing 2-3/4" shells in
2-3/4" and 3" chambers. I've not been able to locate that FAQ recently,
but I didn't try very hard either.

This opinion is by no means universally held. Beretta makes just about
all their 680 series O/Us with 3" chambers, even the competition ones. I
think that Krieghoff does too. At least the 28 gauge K-80 I tested some
time ago had 3" chambers and there isn't a 3" 28 gauge shell being made
that I know of. Two months ago when I was working on a review of the new
Blaser F3, I asked the president of the company why the picked 3"
chambers for a sporting clays gun. He said that they did extensive
testing and found that the 3" chamber was absolutely no disadvantage
with a 2-3/4" shell. But- Browning thinks the other way, as do some
other makers.

You are going to shoot 3" shells in a ported barrel? If that's going to
be in a goose pit, I sure hope that anyone to either side of you has
earmuffs and full battle dress.
