Gonna re-use an old 6.5-284 barrel myself...
Spec'ing a reamer for it now.
Loaded rounds run 0.2900 - .2906" at the neck with 142/123Sc/123SMK So I'm thinking .293 for a no-turn nk.
I have some average base dims too...need to get my notes together.
Just figured out OAL requirements for it last night to get the right freebore.
Unfortunately it won't be ideal to get a 142 and 123SMK to work in the same chamber, but I may try it.
with the 142 seated at the absolute bottom of the neck, the 123SMK is about .120 ABOVE the N/S junction.
the 123 scenar is only about 40thou above.
the 123SMK is a good bit smaller than the scenar, but sleek and slick.
Thinking I'll start with perfect seating for the 123 scenar, and if i can't get the 123's to work, punch the freebore 40-50thou and the 142 will fit perfect.
the 6x47 is doing all we thought it would a year ago...easily getting 3100 accurately in a BR platform with the 105/6/7 bullets...and shooting well at 1K [img]/ubbthreads/images/graemlins/wink.gif[/img]
Judging by the successes with the 6mm version, 3100 should be feasible with a 123 scenar in the 6.5 version...
Here is my photo lineup from last Nov. of some other little guys. Click and scroll down:
You planning to run solely 142's or more towards the 123?
