Yes. You should not use modern off the shelf ammunition in these old guns. T-32 does indicate the gun started life with 32-inch long twist barrels. If the gun is vetted as sound by a qualified double gun smith, one can use low pressure handloads or get quality low pressure ammunition from specialty ammunition companies such as RST -- http://www.rstshells.com/

A.J. Aubrey -- Albert James Aubrey (Feb 23, 1862 to Dec. 3, 1947) was born in Meriden, CT., and by the 1880 "U.S. Census was, at age 17, listed as working in the gun factory, likely Parker Bros. (My math says he should have been 18, but the census says 17?!?) On Nov 25, 1891, Albert married Miss Blanche Boomer of Wilkes-Barre, PA. in Fulton, New York. Maybe he was working at Hunter Arms at that time. The 1893 Wilkes-Barre City directory listed Albert as plant superintendent for the Wilkes-Barre Gun Co. When Wilkes-Barre Gun Co. folded the 1895 WB City directory lists Albert as removed to Elmira, NY.

Albert became manager of production for Sears, Roebuck & Co. in 1904. He convinced Sears it would be more profitable to make their own guns then contract out. In 1905 they bought a factory in Meriden, and with Albert J. Aubrey as vice president formed the Meriden Firearms Co.

Meriden Fire Arms Co./A.J. Aubrey doubles were made from about 1905 to WW-I. In all likelihood very few of them have ever seen a black powder shell. Wood smokeless powder became available for shotguns around 1876 and by the 1890s numerous, both bulk and dense smokeless powders, were dominating the shotshell market. By the time Meriden doubles came along, black powder shells were mostly for poor share croppers Zulu conversion single barrels --
