What form factor is this? Too high for G1 BCs.

Form factor is a metric to compare how high a bullets BC is given it's weight and diameter. Lower form factor # = better in regards to how slick a bullet is aerodynamically. G7 BC = Sectional Density of bullet / Form Factor. Most companies dont publish that number but it is an interesting one to use in comparing berger bullets.

Form Factors: A Useful Analysis Tool

In 2009, Berger Bullets introduced G7 BC’s for boat tail bullets. For those who are unfamiliar with G7 BCs, it’s simply a Ballistic Coefficient referenced to the G7 standard projectile instead of the G1 standard projectile. The G7 standard is a better match for modern long range bullets, so the...

Form warned me about the Eldms, but I haven't seen it firsthand. The only other animal I've shot at sub-2000 FPS with eldms was a bull elk, which I took down with a 147 eldm, and it worked as usual. This experience only reinforces my love for the 6UM.

I wasn't planning to shoot the 7PRC that day — nor at that distance, although I had validated it up to 1200 yards the day before. I had taken my son-in-law out to shoot a doe, but I went to a spot where I had seen a big buck the week before. As luck would have it, I spotted that buck chasing a doe and moving toward the timber. I tried to get my son-in-law on the buck, but he couldn't find it in the scope. I told him to switch to the spotter.

I hit the buck with five out of six shots, only spotting one hit, VERY frustrating. My son-in-law said I was shooting high, but I was actually shooting through him. Lesson learned: only hunt with a 6UM when big animals are on the table!

Interesting! and somewhat disheartening.

With that being said, I took a buck at 730 a few weeks back with the same exact bullet out of a 7PRC. Impact velocity would have been about 2020FPS and it shattered the scapula, broke 2 ribs on the way in, and the organs were liquid. Deer didn't take a step.
