I am based in the UK, and I am about to acquire a 6.5 x 68.
It is a 6.5 based on the 8 x 68 RWS case but necked down. I also have little experience of the 6.5, and was going to post until you beat me to it!! Looking at the loading Data, the Rem Mag,Win Mag, and 68 all come out very close, so there should be little between them. However, the 6.5 bullet in the heavier loadings has some high readings for sectional density. It should be a good penetrator.
I look forward to the replies. I am intersted in size and distance of game that it is felt can properly be taken with the 6.5 bullet.
