    keeping all the other things the same; start low and go up in powder, .5 grain increments usually ; load maybe 8-11 rounds stopping at max in manual. two or more bullets in the same hole indicate a sweet spot. drop down 4 to 5 grains from max and load one round in .5 grain increments.

    Everyone has an opinion, Ron gives good advice. My thoughts are a 200+ grn bullet with H1000 and a 215M primer. If you want to stick with the 180s I would use a stiff charge of Imr4350 or H4831 with a 210M or WLRP. Any of the tangent ogive pills should shoot decent at mag or saami length, the secant ogive pills can be finicky with a lot of freebore.
