Train with M855, which JSP to use for home defense?

[markm]

Have you thought about a Mk262 type round? MY 1/9 CL barrel shoots ~.6moa with Mk262 cloned handloads. Don't ask me how, but it does. I was really surprised.

You'd be surprised. Almost every CL barrel we mess with is capable of MOA +/- with good ammo. And the most accurate gun I've ever shot is the REM 700 5R 1/9 twist that Pappabear owns... with 77s.
