I usually stick to low power variables like a Leupold 1.5 -4 or a fixed low power . I have an old Leuplod M8 3 power that has been on more rifles than I can remember . It's sitting on a Savage single shot Model 219 , chambered in 30 /30 , at the moment . I've found that I use the lower settings a lot when hunting in thick cover , sometimes , less is more . I've used a few Scout set ups over the years , they do work , but they have a fairly small field of view when compared with a receiver mounted scope . When using 45/70's , keep in mind that the more eye relief , the better . Ask me how I know lol . I hunt with two guys that use high velocity, heavy bullet loads in their 1895 SBL's , they both have intermediate eye relief , low power , scopes on their rifles to avoid the ocular cookie cutter , something to keep in mind if you intend to go that route . A stainless version in either caliber would be a good idea in the UKs humidity . A blued version is fine , but a stainless rifle is easier to maintain . They are a bit flashy though . There's a picture on here somewhere of an SBL that I ceracoted to make it a little less noticeable , important when you're shooting animals at close range . There are a lot of after market accessories available , especially for the Marlin 1895's and 336's . You can customize them to suit your taste or needs .................... and you will .
