New to reloading and would like to know if any one uses n160 , n165 or n550 powder for your 300 wsm loads? Using Hornady eld-x 175 and 200 grn bullets. The rifle is a Winchester feather wt stainless 24 inch with 1-10 twist. Thinking of using n550 for the 175s and n165 for the 200s. Any input , appreciated
