[QUOTE="pvanwyk, post: 153922, member: 3421"] seem to be getting nowhere with my stock standard Sendero in 300rum. We have a limited amount of local powders to choose from which makes the frustration even more. First loads with the rifle produced 0.5MOA straight out of the box with 200gr SMK's and a local powder that has a burning rate equivalent to H870, (CCI mag primers). Varying burn rates with the local powder (specifically the H870 equivalent) from tin to tin has made an almost impossible task of trying to duplicate that load. We have more consistent powders that are equivalent to H4831 and IMR 4350 but I'm not convinced that they're slow enough for such a big magnum. Any help would be appreciated with the following. preferred bullet is 220gr, or 200gr smk. - which primer CCI bench or CCI magnum ? - should I perservere with local powder equivalent to H870 or has anybody had fair results with H4831 (next slowest burning powder equivalent that we have locally) - Should I try using a lighter bullet (180gr) ? Your help is appreciated Paul (South Africa) [/QUOTE]
