Re: amax/accubond b.c. wanted
Funny thing about the 178 AMAX is it will vary in a LARGE way depending on what twist youre using and how fast you drive em.
Published is .495 or .496. I assume the factory is using G1?? My experiances have been drastically differant. Out of my 11.25 twist 308 at 2550 FPS I was getting .318 G5. Out of my 12 twist 300 RUM, I am getting .495 G7 which is amazingly flat. Close to 1.011 G1. That is unbelievable.
I havent fired the 180 AB past 300 yards, but have fired the 200 AB out to 600 yards and its BC worked out to right at .588-.590 which is what they are published at. I would suspect that the 180 AB is going to be very close to .507.
PS, There are several others here that have had similar results with the AMAX's with a variety of calibers and weights.
Long range shooting is a process that ends with a result. Once you start to focus on the result (where the shot goes, how big the group is, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.
