Default RE: 6.5x55 vs 6.5-284

I am going by my Nosler manual and comparing a 140 grain bullet and there was 100 fps. 2900vs 3000
Its probably possible with a Nosler partition- in my experience, they have a very short full diameter bearing surface, while the full diameter bearing surface on the SMKs that I normally shoot arequite long. A different powder might give a bit more velocity in the 6.5x55 as well- I use RL-22 because its known to be one of the best powders for accuracy in the cartrigde, but its a very slow burning powder relative to the case size.
