My Farmingdale Business Rifle weighs 11.4 lbs, the current Sporter weighs 10.6 lbs, both with sights. The 28" barrel of the BR measures 15/16ths at the muzzle. The 30" octagonal barrel of the Sporter measures 14/16ths at the muzzle. The Business Rifle is noticeably heavier when you pick it up.
The advertised weight of Sharps rifles is moot, depending on wood density, barrel dimensions, etc.
I agree with the lack of lube on the 457193 bullet. I get better resuls with a grease cookie or lubed wad.
As for the stocks, the BR has a straight grip, the Sporter a pistol grip, making it easier to hold, especially off hand. I find it almost impossible to shoot past 100m offhand with the BR due to the weight and straight grip.
Sir Charles - your 45-70 load must kick like a mule in your '86 SRC! My '86 rifle is quite pleasant to shoot with 62-65 grs FFG and the 457193. I watched a friend shoot some of his silhouette loads in an '86 carbine, five in all. When he was finished, he put his head down on the bench and was still. Someone touched him and asked if he was OK. Answer - "Yes, I'm just trying hard not to cry."
I still want one, if i can find one at reasonable cost.
