Tested a 28 Nosler a couple months ago....and the best load was 160 at just under 3350 fps...
Granted, it is fast.
What do you reckon Nosler's "flat out, lights out" Herd Bull MPBR is advertised at?
Don't know how Nosler measures PBR,but probably so close to the 26 Nosler you'd be hard pressed to tell the difference.
I just ran the quick and dirty numbers through a ballistics calculated, with the 160 AB at 3350. From a 300 yard zero the drop at 400 yards is 7.8"; 13.5 at 450,and 20.6 at 500. That's "flat" for a BG rifle and bullet.
In comparison I ran the numbers for the Mashburn with the same bullet at 3200 ( I would call 3250 as top end). From a 300 yard zero the Mashburn drops 8.6 at 400; 14.9 at 450,and 22.8 at 500.
We can play with vital area numbers and come to our own conclusions. The differences exist but are not great.
Keep in mind the Nosler numbers are from a 26" barrel and the Mashburn a 24".
I bet if we fed the Mashburn a 162 Amax there would be no difference at all....but we won't go there. Just a thought.
