I have the option of picking up a used rifle in the said chambering with a 9 twist benchmark barrel. I'll be at 800' elevation. What bullets do you think it will stabilize?
 
I have a 26.5 inch Shilen 1 x 8.5 twist it likes the Sierra 142's a lot. I am playing with some Berger 130 hunter vld's in hope of deer season.

I am at 5000 ft. Today it was 100 degrees f out. H4350 no problems.
