Excellent Kman! Lots of work and thanks for the effort.

Looks like the 220 Partition tumbled,shed the core. Had it happen once. The 180 TBBC looks good to me.

Of the 6.5's the only one I'd bother with is the 127 LRX.

Interesting stuff with a couple of surprises.On average the 30's did better than the 6.5's which is no surprise.

The 280 Remington is overbore.

The 7 Rem Mag is over bore.
