And...we have a winner!...A 300RUM will push a 101g Hammer Blackout @5000fps. My 300wsm shoots 55g sabots at over 5000fps.
Here is a fan experiment, if you think BC is not a factor in MPBR try loading the 115 VLD backwards with the same charge and see what your actual dope/drop. Yes, there a guy that did it with CEB (ESP Raptor) - without tip, with tip, and backwards.II'm currently shooting a 25-06 which gives me a MPBR on a 4" target of 298yds with a 115vld.
^^^^^^^^^^^^ This ^^^^^^^^^^^^^^^^^^^The answer changes quite a bit depending on range. Within 300 yards or so, anything shooting little bullets over 4000 fps will win. A 22-250 with 40gr bullets comes to mind. At a mile, it depends much more on a bullet's BC and SD.
Your data doesn't pan out. The OP is talking about 2" up and 2" down for a 4" total. The numbers on your example only come close at 4" up and 4" down for a total of 8".Using my data in Strelok for a MPBR for a 4 inch target as the OP was doing:
28 Nosler with 162 gr eld-x 370 yards.
6.5 PRC 143 ELD-x 343 yards
.22-250 handload with 35 gr @4500fps 423yds.
I was waiting for someone to say this. With its speed, MBPR should be way on out there past any other 22 reasonable for small predator poking. There is also the .224 Wby and .220 Rocket as well.220 Swift
