I don’t think that was one of her house design criteria, I forgot to tell her
Currently have “Boar Busters” in my home magazines… might make big holes in a wall, but hopefully not go too far afterwards. Time will tell, I guess, I’m not allowed to test
Those look like a bonded soft point. If the idea is TO punch through multiple walls while holding together, you’re on the right track. It looks like a decent choice for a barrier blind round.
.308 has a LOT of energy, and the bullets have ~3x the mass that 5.56 does, which basically means just about any of them will easily punch through multiple layers of drywall.
A bonded soft point .308 will also punch right through joists and studs while retaining lethal energy (hence making them good options for barrier blind ammo).
I don’t think there’s a single commercial .308 round that won’t punch through regular interior walls.
Of the available options though; Sierra’s TMK (Tipped Matchking) offerings in 5.56 or .308 are absolutely devastating on soft tissue.
You can find YT videos of testing on ballistics gelatin. Almost no neck to the channel. Impact immediately slams the polymer tip back into the bullet, which initiates the catastrophic disintegration of the bullet, resulting in a particularly nasty channel. The effects of the .308 variant are an exaggerated version of the 5.56.
That action of the polymer tip initiating destruction of the bullet, also means it’s sub-optimal as a barrier blind round, but either the 5.56 or .308 will STILL punch through drywall and remain lethal. They just won’t punch through as many layers of drywall while remaining lethal, as a bonded soft point might.
FWIW, my preference for HD is a bunch of 5.56 77gr TMK, followed by RA556B (Winchester’s 64gr bonded soft point. Hard to obtain for regular folks). I figure if anything forces the use of this option, and the initial offerings of TMK weren’t enough, I’ll want some barrier blind capabilities (same reason the Benelli M4 has FliteControl #1 in front, with Brenneke slugs at the end of the tube, and more Brenneke slugs in the side saddle).
