Re: 6.5x68 vs 6.5x65mm

In reply to:
Well the 6,5x68R is a little bit slower than the non rimmed 6,5x68 but it is not very much. The 6,5x68R is just about 15m/s
slower... A damned hell of a rimmed cartridge! But as i told you before have a look at the correct twist!
I recently revisited the references books and yes they did list the too cartridges together. Somehow I got into my mind that the rimmed version was slower.
As for twist, if the rifling twist is correct for 90 gr to 140 gr projectiles that is fine. I do not want to shoot 160 gr projectiles in this hot-shot.
