[QUOTE="Michael Eichele, post: 291591, member: 1007"] I would be willing to bet the 177 despite its all copper construction would very very easily be well over the .550 mark. Some years ago, I tested the old Barnes 180 grain XBT and all be darned I came up with exactly what was published. That was .550 for a BC. Now that was before the grooves AND the nose was more streamlined. This being the case, I could see where the 177 being much more streamlined than even the older sleeker XBT, could have a higher BC. I would be willing to bet that the 177 would come in higher than .550, he!! the 180 E-tip is .523 and is really really close to that. If that short boat tail and tangent ogive can yield .523, surely the the 177 can be much higher. I am guessing .575 to .590. My next barrel WILL be a 9x 26" 30 cal. I will dinking around with the 177's and 180 HAT's. It wasnt me that tested the 210 Bergers but I have tested the 208 AMAX and came up with .671 which is higher than published. This was also concluded by double chronies. [/QUOTE]
