The M1895 Lee Navy-our only real lemon of a service rifle. Caliber too small, the powders of the day too hard on the bore, no proper cleaning rod, the floating extractor was easily lost.
My idea of a misfit is a rifle like the M1895 Lee Navy-or the Ross-that is well made but has serious design flaws that make it unsuitable for issue. Then there are designs like the Dardick that are intriguing but....what's the point? What do they do much better than a conventional design ? The Gyrojet-the same.
The explanation given to me of the problems with Remington's 5MM Magnum was that it was basically Remington's proprietary version of the better established 22 Winchester Rimfire Magnum and there were some quality control problems, complaints of erratic pressures, etc.
The 45 GAP-coming up with a 45 semiautomatic round that is incompatible with the 45 ACP ?
The Bren Ten-like the 44 AutoMag-seems to have been a business failure, an undercapitalized company trying to rely on customers' deposits for funding-not a wise business practice.
