so im thinking about a 6.5 x 55 sweede ackley,

in a long action it would gain 5 gr powder capacity by being able to seat bullets out long, plus and extra 5 gr or so from ackley dimensions

so basically gaining 10 gr capacity, i would think you could match or exceed 6.5x284 performance with cheaper brass(70$/100 lapua brass) and being able to use LCD

any holes in this story??? anyone done this?

TIA
