Forgot to mention, I'm getting 2500fps, with the Partition/Amax loads. The 6.5calibers just seem to work really well even starting out at what we would call low velocity these days.
I personally wouldn't have any issues shooting a 200# deer out to 250.

And that's perfectly adequate for my purposes, as shots longer than that are very unlikely on any of the ground I hunt; most being much closer. If I find myself hunting where really long shots are possible, I have other rifles.
I compare manufacturer velocity recommendations for proper expansion with data from ballistics tables to be sure I'm not straying from the path. Based on that, the 123gr SST factory load should be good out somewhat farther than 250, if the opportunuty arises. I've started using a local range that goes to 300 yards, so I'll be able to verify trajectory and my own ability out that far, anyway.
I appreciate everyone's input.
BTW, I got a notice from Midway this morning that they have 123gr SSTs in stock and on sale. The 100 rounds of factory ammo I ordered arrives today as well, but the rifle remains in the wind until my check gets to the dealer.
