Re: Highest B&C bullet for a 12 twist 30cal.
I also used the 178 AMAX at about 2550 and found it to be nothing special as far as trajectory. It was .318 on the G7 curve for my circumstances which is close to .475 on the G1 curve. Published at .496. The interesting thing though is when I use the 178 AMAX in my 300 RUM 12x at 3100 FPS it follows the G7 curve at .496 which is truly an unbelivable trajectory!
You mentioned someones claim of 1.00 with the 178 amax and if you convert from G7 to G1 1.011 is a close match in trajectory between .495 (G7) and 1.011 (G1) Trust me its happening!
I think there is a pattern here. Seems like when guys are shooting the 178 AMAX at medium to lower velocities they dont see any special trajectories. When they launch them at higher velocity, the trajectories are inperpotionatly flatter when compared to other bullets.
Any other thoughts or experiances??
Long range shooting is a process that ends with a result. Once you start to focus on the result (how bad your last shot was, how big the group is going to be, 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.
