After messing around with ---the odd rim size,--- various throat lengths, ---differing twists,--- pressures.
I came to my Looney senses and realized I was messing with all the 6.5 oddities when I already had a perfectly good cartridge in my safe.
I can easily load my 270 to achieve the soft recoil of the Swede with matching ballistics
I'm on the threshold of "it ain't worth the effort"....too,
with a 270, I'm already there.
