With this , we are limiting the cartridge to only one achievable velocity . If we handicap our selves with this parameter, Then, BC becomes the only thing that that can change the maximum point blank range.
In the real world, ANY CARTRIDGE MADE, will have a greater MPBR, with a lighter weight fast pill.
For example, the old favorite 30-06. Loaded to saami pressure with a Nosler 210 ablr, g1.661,
200 grain accubond,
150 grain accubond, and
125 grain accubond G1 .366
Which one has the greater mpbr?
Feenix, I know you are a very intelligent person, and I know you that you know these are facts.
No.
The only way to increase range in regards to MPBR, is to decrease TOF to the target in order to keep the maximum trajectory parameters set by the shooter.
Probably somewhere around the 45" MPBR target size is where the 210 ablr would catch up with the 125 ab. (Just a rough guess, driving, no time to run the numbers).
Let me be clear. I love high BC bullets. I shoot 300 grain pills in my my longest range rig. Light and fast won't do at extended ranges.
But for point and shoot, no dialing,
4" to 6"target MPBR, light and fast wins every time.
