Daryl, I think you will find that you can get a fair bit more out of them with a 26 inch barrel which is the norm for 256 Mannlicher. 25 and 28 were also commo9n but mostly 26 inch. You need the long barrel so that the rifle balances with you hand just forward of the magazine, which they do really nicely. Also helps with a long sight radius as most of that model are open sights. You can fit optics but it is more difficult than a MS as you must load the magazine with a clip of five rounds meaning the scope must be easily movable or off to the side which is a bit crap.

Matt.
