planning next build;
.260 Remington AR-10- Mega MATEN monolithic upper & matching lower
- Krieger 1:8 twist SS barrel
- Rifle gas system
- Suppressor (brand undecided)
- Nightforce scope
- Magpul stock & pistol grip
Why .260 Remington?Looking at the dimensions of the Berger 140 hybrid bullet (1.43" length, 1.23" above boattail),
plus the .260 Remington case (1.57" at base of neck),
equals 2.80" (1.23+1.57), which is exactly the design magazine COAL for .308 AR10 magazines.
It's like Brian Litz had the .260 Rem in mind when he designed the 140 Hybrid...
Secondly, .260 Rem has a 1000 yard drop/drift of 25.0/5.5 MOA and a max supersonic range of 1400
(At my atmospheric conditions, and 2750fps muzzle velocity)
Better drop/drift than a 300Win Mag, burning 2/3rds the powder, and both Norma and Lapua make brass for it.
Though.. I may have to take a closer look at the SCAR-H.
Supposedly, the barrel changeout is stupid simple.
