davidindallas, I agree 100% with everything said here by CptCurl. I have a pre WWII Ferlach Austrian made O/U in .270, a pretty intense non rimmed cartridge for double rifles, that has never malfunctioned in any way. I prefer a scope on an O/U, compared to scope on a sxs, so a small scope works beautifully on this rifle. Have used it successfully for deer hunting numerous years. I am a traditionalist too, but this .270 convinced me that such cartridges can be used successfully on double rifles, IF built correctly.
