[QUOTE="Ridgerunner665, post: 713174, member: 12660"] It is very unlikely that the BC's are much more than 10% off...the average for Ballistic Tips in Bryan's test was 6.33%...with Nolsers lighter for caliber bullets being overestimated the worst....if you remove the light for caliber bullets from the average, its much better. The worst was the 120 grain 7mm bullet...at 12.7% The 117 grain 257 bullet...........................at 10.76% And the 125 grain 30 caliber Ballistic Tip at ...9.58% The 200 grain 30 caliber partition deserves a mention here...because Nosler actually UNDERESTIMATED that one by 3.99%...its advertised BC is .481, Litz came up with .501 And the BC's Nosler has on these new bullets are still pretty darn good even if you subtract 10%. I have not (yet) read Bryans books...but I did find parts of his testing online...and what I understand from it is that the light for caliber bullets are overestimated the most (in most cases)....I'm guessing thats an issue with the computer program that spits out the BC's...and it wasn't only Nosler, all except for Sierra had some pretty bad numbers (Nosler was the worst though)...kinda tells you who actually shoots their bullets to come up with BC's, or at least that was my impression...could be wrong. Sorry...I couldn't help myself...had to defend Nosler a little, they sure have filled my freezer enough times to earn it. [/QUOTE]
