[QUOTE="Michael Eichele, post: 170058, member: 1007"] I think you are under the impression that I am talking about a wide difference of BC with the same load. This is not the case. Each one of my loads has a very concistent BC. The loads I am using that yield .590 are very concistent. Another load I am using is .459. I can count on .459 being a "constant" for my ballistic calculator as long as I am using the 95.5 BMG load. When it varies so much it is typically due to a completely different set of circumstances like from one rifle to the next. Or a major difference in the loading components or procedures. For example one of my current loads for my 300 RUM is a 200 ACCUBOND using 95.5 grains of H50-BMG powder that load has been giving me a very concistent BC of .459 It is kind of dissapointing but shoots accurate and doesnt beat up my brass. Another load I have toyed with using 86 grains of RL-25 gave me .590 at least out to 600 yards which is as far as I have shot that load. I get a better BC but it is a very rough load on my brass. Why the huge difference? I dont know, but it is what it is. One load does this, the other does that. This post will probably get me in trouble with some here but my advice is get out there are try it for yourself. If you shoot and reload long enough, you will come accross some very bizarre experiances, esspecially in the BC department. [/QUOTE]
