I think that you should take a look at the Hornady Light Magnum ammo. In the US, the ammo manufacturers load the 6.5 kinda low (because of older guns). However, thank goodness for Hornady because they have raised the velocity with their Light Mags. (Although I'm not sure if Hornady still has the 6.5 in their Light Mag line-up - mayby they dropped it, but still have it in their regular line-up). Don't get me wrong...I know that the purpose of the 6.5, in part, is that it is light recoiling. However, don't think that the Light Magnum ammo is hard kicking. It's just a little bit more than standard US ammo.
Another choice would be Sellier and Belloit (or spelled something like that). Take a look at the European ammo makers since they load it to a bit higher pressures.
Also, remain confident in this cartridge. It has been used by hundreds of hunters in Europe and has equally killed hundreds of Moose!
