This topic came up on my post about ring height and I thought I'd give you a good easy fix to those of you that have to have higher rings which make you not be able to settle in on your butt stock correctly. I've done this to both my Marlin 1895s (my Guide Gun and my 1895SBL).
Buy yourself one of those Uncle Mike's elastic cartridge holders for your butt stock. Then go to the pool section of your local Wally world and get a pool noodle. Cut off a length of the noodle about 2" shorter than the cartridge holder and cut it down the length of it. Now cut it down the length again removing about 1/3 section of the noodle. With a sharp knife or razor blade round off all the outer edges and stuff it under the elastic cartridge holder on top of the butt stock. Then position the whole deal on the butt stock where you need it.
If trimmed correctly you won't see the noodle at all and you'll have perfect alignment with your scope. The noodle won't slip around and will not absorb any water either and it is comfortable on your cheek.
