The article in question was written by Peter Barrett in the 1979 Gun Digest & is titled "Two inches of Pleasure & Problems" in which the writer discusses buying a 5 1/2 lb. two inch chambered sidelock Holland & Holland (never mentions if it's a Royal or a Badminton & I can't tell from the pictures) & proudly tells how he basically ruins the gun by lengthening the chambers by 1/6" so he can shoot his "special" 1 1/8 oz handloads in it for grouse & woodcock.
The problem is that after he has taken this fine gun out of proof he discovers that his "special" 1 1/8 oz handloads pressure test @ over 15,600 LUP
so he has to settle for his 1 1/16 oz "special" handloads @ 9,900 LUP.
I't difficult for me to understand why someone wouldn't just buy a 2 1/2" chambered gun in the first place if they felt they had to shoot more than 7/8 oz loads for grouse & woodcock but to be fair it wasn't all that uncommon in that era for people to lengthen 2 1/2" chambered guns to 2 3/4" thus taking them out of proof & shooting much heavier loads than the gun was built for .
