Just had a thought. Given that 6.5x284 brass is hard to get, I was wondering if a 7mm version of the 6.5x55AI would be equal in performance? Would the case capacities be similar if not the same?
Been there thought of that the case capacity of the 55, 57 is about 4 grains of H2o less than the 284, but with the better case design you maybe able to run higher pressure and get similar velocity, or run the 162/168 type bullet at higher velocity.

6.5x284 cases are listed as available on the Q store/shootenstuff website. Even then there are nosler custom and hornady cases available. A bit more prep needed but might be a short term fix. Bob K has been running prepped remington cases in his SAUM and it shoots unreal.
And for 6mm version of 6.5x55 you should find it on the web somewhere just google it, Better sticking with the 6.5 and run 130 or 140 bullets though.
I take it they are the soft ones? I just picked up some from a mate in Perth a week back that he bought way back when blue boxes were fairly new and going by the lot number, they are from a much older batch. Fingers crossed they handle being run as 284S well. He even primed them for me too!
I would like to know if anyone has tried running nosler custom or hornady cases necked up and prepped for uniformity. Wouldnt be a bad idea for club cases if you wanted to save good lapuas for matches.

I think the Nosler and Hornady are made by Norma (very uniform BUT, in the past have also been on the soft side), but could be worth a try, just treat them gently to start with.

Those Lapua cases they're listing are the ones I bought (& regretted), lot P00620601.

John,
They are also the ones I bought and DIDN'T regret it . I used them at the FCWC and found them about the same as any other batch. In fact when I was doing velocity comparisons between Australian & US powder batches, one ladder ended up at 3033fps, and the primer pocket seemed okay next time I primed it.
