The reduction in velocity has decreased the 17gr Vmax's effectiveness by 20- 25 yards. About a 5% decrease in power. Doesn't sound like much right?
The impact velocity at 50 yards used to be just over 2300fps. Now that same impact velocity is at only 27 yards!! It used to be just over 2000fps at 100 yards, but now it reaches the same speed at only 77 yards!!
I'd call that a significant drop in killing effectiveness.
