In 1992, Winchester added an unsightly and generally disliked cross-bolt safety to the receiver of Model 94 rifles, including the Big Bore. All Big Bore 94s were carbines with 20" round barrels and a full length, under barrel tubular magazine that held six cartridges. (Contrary to some reports, this was not a recoil pad.) Big Bore rifles circa 1983 had a Monte Carlo comb, others had a conventional straight comb. The stock had a straight hand and terminated in a thin rubber butt pad. The XTR designation was dropped in 1989, although the rifles remained the same. A folding rear sight replaced the earlier semi-buckhorn rear sight to clear a low mounted scope.īig Bore 94 rifles received what Winchester called the XTR treatment, including a highly polished blued barreled action and a checkered walnut stock and fore end. Angle-Eject allows low and overbore scope mounting and AE receivers are drilled and tapped for top mounted scope bases. When the Angle-Eject action became standard across the M-94 line, starting in 1982, the Big Bore rifles incorporated the new feature. In addition, side mounts for riflescopes were available. The top eject action was supplied with standard Model 94 semi-buckhorn rear and hooded bead front sights and was drilled and tapped for receiver sights. The anticipated sales never developed and the project was shelved.įrom 1978 through 1983, Big Bore 94 rifles were built on the post-1964 top-eject action. 45 caliber cartridge to complete the line. 375 Winchester cartridge been as commercially successful as hoped, the folks at Winchester intended to introduce a. I remember reading that, had the Big Bore 94 rifle and. 38-55 +P load that exceeds the killing power of the Winchester. 38-55 cartridges, including the Buffalo Bore Heavy. Actually, although most owners do not realize it. 375 Winchester was based on a slightly shortened and strengthened. 356 Winchester were essentially rimmed, internally strengthened versions of the existing. USRAC purchased the rights to the Winchester name in 1981 and rifles made under USRAC management were marked, "U.S. I understand that butt pads on the early rifles were marked, "Winchester Repeating Arms" if manufactured before January 1981. It was, in fact, the last new model introduced by Winchester RAC. The Big Bore 94 was introduced while the Winchester Repeating Arms Company was still owned by Olin. Serial numbers on Big Bore rifles were preceded by the letters "BB." (The internal parts were identical to the standard Model 94, only the receiver itself being beefed-up.) The new calibers were. It was built on a strengthened version of the regular Model 94 receiver intended to accommodate a new line of rimmed cartridges loaded to a maximum average pressure (MAP) of 52,000 CUP. Winchester introduced their Model 94 Big Bore in 1978. Bottom line–the upcoming book will provide real, measured twist rates for all of the calibers of 1895’s, and I am betting the date brackets from the serial numbers can be derived or inferred if the rate changed over time.Model 94 Big Bore XTR (top eject model). The bigger details will remain, the finer details get fuzzy. Bear in mind, this is from my memory and I am finding it fools me at times now days. Some of them agreed with what was measured, but seems I recall some did not. As I recall, the “blackpowder” cartridge guns were in very good shape, and the twist rates were consistent and agreed with other data.Īs I recall, Brad had written data from “olden” times from some hunting magazine writer, if I recall, that gave the “correct” twist rates for the differing calibers at that point in time. It took a series of efforts in driving a lead slug down the bore ahead of the rod, then averaging the outcomes, for me to say what twist rate my Russian musket was (and at this point I don’t even remember what it was!). I can add that my Russian musket was a challenge to determine twist rate as there were sections of the bore that the rifling was weak enough or even missing that the cleaning rod was not even rotated for a short distance. This will be included in the upcoming 1895 book that hopefully will be published yet this calendar year. However, some of us measured (as best we could) the twist rates of a fair number of 1895’s in the differing calibers. Perhaps Brad will add to this or maybe even correct it.
