Got the BSF 223 out today for break in. Compensator arrives Tuesday so I stopped by the LGS for a thread protector which I basically hand tightened down against 2 crush washers. It did loosen a tad a few times. Zero'd at 50 yards per scope instructions and each shot pretty much went where the adjustment should send it. Took advantage of a target someone left on the 50 yard board. This was with 32ยข Norma TAC 223 55gr FMJ. Both are three shots. The stringing on the second is likely me. Both off front and rear bags and I had to use charging handle to chamber each one - wasn't cycling and I need to check gas block alignment.

I think it will work! Groups widened significantly to 2 MOA at100, but that's pretty much been my experience with the ammo through 1:8 twist barrels.
I think the barrel is a tad on the fast side - I got 3075 with the Norma vs 3070 I get with my 20" BHW (which has 5P rifling and is pretty much average) and 3150 that I used to get with my old 24" Anderson bull barrel. Probably a little bit due to the tight chamber.
Looking forward to working up 77s. It should be a sub MOA barrel with decent ammo and I'm pretty hopeful that the 1/2MOA potential is indeed there.

Let's go Brandon!
