There are more reasons wherefore Marlin 1895 SBL comes in cycles. For example, everyone wants a reliable and solid .45/70, so every new batch sells out fast. The reputation of the gun is also part of the process, but Marlin is trying to produce more SBL versions of other guns too. It may take a while until Marlin 1895 SBL becomes more common. Until then, whenever a new batch comes out, it tends to sell out straight away. There are times when even ammo might be a bit difficult to find. The low availability has obviously increased the selling prices as well. Despite the official retail price recommendations, a high quality gun will sell for much more.
