Parker Chamber

[Dean Romig]

In my opinion, wall thickness at the juncture of the chamber and the beginning of the forcing cone is far, far more critical than chamber length differences of a sixteenth or an eighth of an inch.

I tried a few times with the paper trick of sliding it to touch the start of the force cone with no luck for me , I could feel it good enough

It sure looks longer then 2 1/2 inch to me , I’m going to search out someone who has a chamber measuring device

The bores looked really good

and this took my breath away when I unboxed it after work , it’s more then I could of hoped for , the colours in the CCH is so nice , looks like a old patina on it
1910 Parker , 30 inch barrels ,
I can’t wait to shoot it ,

Handsome gun, very nice!

I've seen a letter reference from a principal at Parker to Capt. Charles Askins and dated in the 20's that states unequivocally that Parker chambered 12ga guns to 2-5/8" and intended for 2-3/4" shells at factory pressure level. I'll look for it later and will post the content if I can find it.

Richard - Poor man's answer. If you have a small machinist's rule, turn it on its edge and slide it into the chamber until it begins to reach the chamber neck, and light will show between the rule and the chamber wall. Read the rule. Bingo

Excerpt from the reply letter from Parker Brothers to Capt Charles Askins:

“Replying to your letter of December 17th [1920] …... Referring to the cone, we ordinarily permit our shells to lap into it 1/8-inch but as a matter of fact we have found that the majority of guns will shoot a better pattern with even more lap than this. …… In user’s hands we do not advocate the use of longer shells than those which give 1/8 lap.

Parker Brothers, per W. A. King”

The chambers in my 1898 DH 12 with Titanic Steel barrels are 2 9/16” and when I shoot 2 3/4” AA’s in it the very tips of my fired shells are pinched… even to the extent of being pinched off. The felt recoil is only a smidge more than when I shoot 2 1/2” shells of equal loading.

Would someone 'not from around heuh' understand this?

[Dean Romig]

Hmmm…

How about an increase in felt recoil of .017 ft. lbs. ?
