I’ve been trying to come up with the perfect long range, mountain, saddle rifle for years. I’ve yet to find the perfect combination of slimness, weight and accuracy that fits comfortably under the leg while on a horse. The BLR comes close except for it reputation for janky accuracy and that god awful trigger. The Long Ranger is also a contender but I just can’t warm up to them. They’re a bit chunky for what they are.
I’ve gone through a couple of Number 1’s, none have met my accuracy standards. I’ve shot some that do but none that I’ve owned cut the mustard. I think the single shot Blaser might fit the bill but they cost to much to be thrown on a horse IMO. I’ve had horses do some rude things to rifles.
I’ve settled on a bolt gun and put up with the size and issues that come with saddling one.
