I was shooting my 1882 G grade Parker Hammergun this weekend in the Texas FITASC SidexSide Event (which I won). One or two people commented how it was really smoking targets which I also noticed. When I returned home I miked the chokes and found they were both .025, but to my surprise found the bores are .750!
Has anyone else noticed bores of this diameter on theirs? I presume the 11 ga bores were made for brass cases and 11 ga wads.

| Leighton, I believe your assumption is correct. In my (measuring) experience, most pre-early 1890s Parker 12 gauge guns are bored around .750 and 10 gauge guns around .790. "TPS" Vol. II has a write up on this. Oh, and congratulations.

Good on you Leighton, glad you whooped em. My 32040 has .752 & .750 bores with .024 and .026 constriction and it will reach out there as well. I have four other Parkers from 21399 to 87426 with bores that run from .731 to .735. I have two 10 bores that are both .802 and they throw very tight patterns.

Leighton; Congratulations; I enjoy shooting my hammer and early hammerless Parkers at skeet and five stand, and most of them have 3/4 inch twelve gauge bores as well.
This is one of the most frequent topics on the forum, and we attempted to answer it in the first "We Get Letters" column in spring Parker Pages. I have had difficulty with posting excel files so I have printed and scanned the file to post as a photo.
Note that 48/64 of an inch is .750; 47/64 is .734
Immediately after King joined Parker (around s/n 3000) he filed for patents on barrel boring methods , noting that twist/laminated/damascus barrels were not very homogeneous, and required special methods to be bored straight and true. The table shows no real preponderance (mode if you are a statistician) for guns below s/n 5000; it was a matter of ream and polish until the tolerance was met. There was about an equal demand for tens and twelves at this time; barrels that did not clean up at 3/4 (48/64, .750) were probably reamed to ten ga, as both guns were predominantly made on the 2 frame.
King apparently mastered inhomogeneous barrel boring after s/n 5000. Note there is a significant mode , and a minor mode in the s/n 5000 - 70000 field. Parker had no significant export business to Britain and no need to conform to British proof laws. They did not need to buy special bore reamers, and could use standard American reamers which came in 1/64 inch increments. A few barrels apparently cleaned up at 47/64, (.735) but most needed a 48/64 reamer plus a little polish to make the grade at .750 - .755
There were great advances in metallurgy around 1890, and fluid steel appeared soon after. Most barrels after s/n 70000 cleaned up with the 47/64 reamer plus a little polish. I account for the few barrels in the .730 - .735 bore range as having been reamed with a sharpened reamer.
The ALL category tells the tale; there may be a collecting niche in collecting Parkers with the English 12 bore standard of .729; less than 1/8 of Parker twelve ga guns have bores less than .730
Best, Austin
