You should get an upper and enjoy them then!
Thanks to the love for the 460, there are many bullets that can survive the added velocity of these “Mega-straight walls”. Along with the benefit of inexpensive pistol bullets for target practice.
Strictly between the two cartridges you mention, a rifleman like I know you are would have no trouble hunting the same with both. The added payload upon delivery is worth the scant bit more thought before the trigger is pulled.
In my opinion, of course.
I find the Bushmaster perfectly pleasant for fifty to sixty shots, and tolerable for 80-90. Those last few rows in the box loom large at the end.
Thinking about it, my shoulder would stand in awe of a Raptor.
But perhaps the heavier M5 chassis would make it the same. Twenty or so 180 grain 30-06 is my limit in a 760. That’s fun part, everything feels different.
With careful shopping one
can get more for their “recoil buck”.
