Re: 300 weatherby ammunition
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.
