Thanks once again for all the help and information regarding the choice I have to make, one thing rings true for sure what ever I choose the most important thing is shot placement with out that nothing counts, and any of the cals seem to work for well for those that use them, going to look at a few rifles this saturday hopefully will get sorted though I am starting to lean torwards the 308 as my local gun dealer has more good used 308s than anything else we will see what happens and will let you know how I get on,
thanks once again to everyone and all their advice
