I've found two neat-looking single-shot rifles in .45-70, but I know little about them. One is an H&R "Shikari" and runs at $250. The other is a remake of the old Wesson & Harrington buffalo gun and costs about $300. Neither looks as tough or as nice as the high-end single-shots, but the price is right. Anyone have experience shooting these brands or models? Are they lemons?
