I don't think I'd be going out on a limb stating that BSF makes a pretty accurate barrel! Still waiting on the compensator so these were shot with a thread protector hand tightened on 2 crush washers (without crushing). I checked it a number of times this afternoon and had to retighten it a few times. Scope is the new Vortex 1-8 Strike Eagle with AR BDC2 reticle. The 1 MOA center dot and no cross hairs don't make it the best for shooting groups.

Load below was developed for my 20" 1:9 BHW barrel: 55 gr NBTV over 24.6 gr Benchmark in a Norma case with GM205MAR. Shot off of Stu Bag in front and Baseline bag in rear at 100 yards at 8x. I stopped the first one after 3 shots so as to not namesake it. 2nd group is 5 shots.

The first measurements tad over 0.3" and the second a tad over 0.75". The MOA center dot in the reticle is bigger than the 2nd group. Wacky thing is 5 shot average velocity was 3075 with sd 7 es 18. Right about what I get out of the 20" BHW. Looks like i've got a short range / varminting / defense load already worked up! Should also be an interesting exercise in twist rates seeing how the accuracy holds up at range (it holds 1/2 MOA out to 550 in the BHW). Also going to print up some targets with a 1 MOA center circle.
Also shot two five shot groups with factory 40 gr Nosler BTV ammo and they were both right around MOA.
So BSF gets a thumbs up in the accuracy department. Some heat testing is also on the agenda in the near future.
