My .243 is a RWS Titan 6 and I have had this longer than any other rifle it's excellent.
I have just bought a .308 Ruger M77 which is a very sturdy big of kit,these are pretty cheap second hand and well worth a look.
Most of my rifles are topped with Docter 8x56ir scopes I really rate them ,Again these are not too dear they can be found for £400to£500.
Just noticed you list a Savage ,another good buy ,mine is the weather Warrior in 7mm-08 ,don't like the weird set up of the bolt but otherwise a lovely rifle.
