id encourage you to review the ballistics and compare… examples with 16” barrels are:
7.62x39 (125 grn, 2365 fps/1552#)
300 blackout (125 grn 2175 fps/1313#, though I do run hand load 110 ttsx at 2404/1411#
the 6.5 grendel gets close with hornady 123 grn (2580 fps/1818#) but that’s with a 24” barrel versus 18”…300 hamr running a 16” barrel, 125 grn Speer Wilson factory load is 2500 fps/1735#
The thin wall on the bolt that grendel uses along with having to run much longer barrel for comparable ballistics for a hunting rifle imo makes this a no brainer…as said, imo, but barrel length to me is a big deal for a hog hunting rig
for long range target or a range rifle, the barrel length doesn’t matter much but you said you were looking for a hunting round..out of ar15 the hamr is top of the chart from what i’ve seen
It’s also very accurate and Wilson usually has a wide range of ammo choices.
my 18” barrel runs 130 grain speer hot core at 2531 FPS/1848 foot pounds of energy and is very stout for hogs
Imo literally what’s not to like about it?
I have considered the 350 but ,I have a lot of
223 brass . For ease of reloading the 6.5 G
may be the best option.i like the ballistics!
I want a new upper ,out of the two for hunting hogs and deer whitch would you pick? I'm thinking Grendel
