Furthermore, seems like you are happy with shooting 0.5 moa. I’m not sure what your shooting discipline is, but 0.5 moa is not a place to stop. To give you an example, my girlfriend and I both shoot F class open and we each shot five 5 shot groups at 300 yards. The largest of those 10 groups measured 0.803” (which is a 0.256 moa group). Possibly 0.5 moa groups are at the smallest end of accuracy for your rifles and you are chasing better accuracy that just isn’t there to attain with your setup.
I love you garandman, but nowhere in your original method do you ever mention “point of impact”. And ignoring that will get you in trouble. Read chapter 22: tuning your rifle, if Tony Boyer’s “The Book of Rifle Accuracy”; pay special attention to pages 253-256. He answers this exact question and his method will get you in tune faster than any method I know of.
Thats basically my process, but in reverse order. Right now, for this new 6 Dasher, Im planning on reversing my current process to do seating depth first. I have no objection to improving my process.
What setup are you shooting now?
That rifle should be capable of 0.25moa all day. If you can’t attain that in the first 200 rounds by tuning the rifle, possibly the barrel is what many shooters call a junker. Not all barrels shoot lights out. In fact, only 2 out of the 10 custom barrels I’ve put on F class rifles were true shooters. The other 8, I constantly felt like I was chasing a good load that would come and go with what seemed like complete random nature.
The guy who built it has 3 times as many match winning trophies as I have guns.
Tony Boyer had the best gunsmiths at his disposal and in his book he states he still managed to end up with 30+ junker barrels. Garbage barrels can be due to stresses built up in the steel, nothing the best gunsmith can do to correct that.
