and is reasonably available
That's the tough part. If you're talking about factory loaded 250 grn Partitions, they're accurate and do the job well. I haven't looked around specifically for that round and bullet lately but I have noticed that Scheels seemed to have more ammo than Cabelas. You might have to do some internet searching or call around. You might also shoot a PM to Nomercy448 as he's located in Kansas and may be able to steer you to a store there. Good luck.
