no they dont shoot .5 moa its 1.5 inches at 100y. the chamber area of the stock has been epoxy bedded, along with front recoil lug, and rear reciever bolt.
I went out and got all the proper tools to do the 243 muzzle crown protector, some heavy cloth patches, and I seated a bullet upside down just out of the case and chambered it protect the chamber. I did it already yesterday I doubt I did any polishing with cloth pathces as lead slugs are used to handlap. But without a borescope its really hard to tell.
