You and your guns Native. Always a good read. So forgive my ignorance, what creates the seal with the bullet ? Go slow cause I know of patches and round balls or sabots. Pretty amazing setup you have. What is the drop at 300 yds with zero at 100, I assume not much? I shoot my ML routinely with 150 grain powder at 275 yds and I know it typically I typically eyeball crosshairs high at 16-20 in drop depending on humidity, but I don't start at 3000 fps at the barrel.
Dogghr, you had the same question that I had about the seal. He explained it to me this way - the explosion makes the back of the bullet expand enough to form a seal. And, he said that he had recovered and examined enough bullets to verify that.
I don't do a 100 yard zero on any of my rifles, but if I did I think the drop at 300 with this rig would be around 12 inches. I do a 200 yard zero, because there is very little rise at 100 yards with a flat shooting rifle. Using the ballistic coefficient provided by the bullet manufacturer (approximately 0.300) and knowing the other variables, we can run it through any good ballistic program and it gives us the drop. When I zero at 200, I am 7.7 inches low at 300 yards.
In essence, this ML has basically about the same drop as a 308 Winchester with a 150 grain bullet at yardages I would consider shooting at a deer - except with the ML I am pushing a much bigger bullet.
The scope I have (along with the chart that he has worked out) allows me to dial the scope for different yardages so that I don't have to do hold over if I don't want to. If I do want to use holdover, below is the numbers out to 500 yards:
100 Yards = +1.7 (or I can dial my scope to zero)
200 Yards = 0.0 (or I can dial my scope to 1.2)
300 Yards = -7.7 (or I can dial my scope to 4.0)
400 Yards = -23.3 (or I can dial my scope to 7.1)
500 Yards = - 48.8 (or I can dial my scope to 11.0)
It's pretty cool, and I really love the gun.
