Groups aren't that bad. I suspect the wind issue was more how it was blowing on you (and your position) and not the bullet. I did appreciate how if you overlap all the groups it still looks pretty good.
I also tend to get a lot of 1 in 5 fliers. My brain gets in the way :) I used to play golf the same way
So what causes those flyers. Powder? Primer? Nut? :)
The Dunning-Kruger effect is alive and well.
I think it's me. I know it took me a lot longer to shoot the fifth shot on those last two groups than it did any of the previous four. I need to treat them all the same, but its hard to do after seeing the first four go very close together.Originally Posted by Robinhood
I've got protrusion down to .049 and the firing pin is more square than round. I'm afraid to take off too much at once so I sand a little and shoot before sanding again.
How it came from the factory. I don't remember exactly what I measured, but it was >.065" if I recall correctly.
After the Desh bushed the bolt. .059".
After two sessions with 500 grit sandpaper. .049".
Well it’s not grouping cleanly so that maybe shooter induced but Ignition would be my guess.
Why don’t You set the Firing Pin Protrusion at .035” ?
We know that light FP strikes are detrimental to accuracy, weak Fp springs can play a part as well as lack of pin fall or drag somewhere in the bolt would show on paper as spitting shots.
I’ve been wrong before and pretty sure I’ll be wrong again.
I'm working on it...slowly. I guess there is no real reason to do it in steps, except that I don't want to screw up the firing pin by taking too much off at once.
Let me ask about those fliers !! Are they random in all directions ?? Are they prone to be
vertical ?? Are they prone to be horizontal, left or right ?? I mainly shoot free recoil. With
the longer barrels, I would string them in the vertical. I was using heavy sand in the front
bag. I switched to a soft beach sand and cut the vertical in half. A bad hold and rest set up
can induce them stray hairs.....I can also attest to shooting bugholes off a concrete bench
and then have them open up to 5/8" off a not so stable wooden bench....Lots of pieces in
the puzzle, and the main reason Beer is brewed !!!

Cool! My son-in-law brews his own as well. Another great hobby!
Yes, to all. I had not thought about sand level in the front bag. I did reduce the ammount in the rear bag to allow the butt to seat deeper in there.
Our range has some steel frame benches set up alongside the concrete ones. The concrete work much better. I think another reason they do is because the steel benches are longer and the barrel does not extent past the edge of the bench. I think I can feel the vibration of the muzzle blast on the steel bench.
So free recoil vs what I call a 'hard' hold. At what level recoil or weight of rifle does a free recoil make sense? If I have an angle on the bottom of the buttstock is free recoil still an option? Sometimes it seems like free recoil works better and sometimes it doesn't. I know part of it is me and a consistent hold. Maybe that's why the 'hard' hold works better for me, because I am in a more consistent position?
Oh, and free recoil. I have seen BR folks not even touching the gun when they 'pinch' the trigger. Others do put their shoulder and check on the stock.
And, yes, the fliers are different. If I have jerked the trigger they are routinely to the right and low. But, if I lift mu head they can be anywhere. And sometimes they are just out there and I don't know what I have done. The sight picture is perfect when the gun goes off.
Those are excellent questions and unfortunately, I haven't kept track of that data. I didn't keep the big yellow and blue targets, but I have kept all the small red and black ones so I can go back and look at that. I shoot off of a wooden bench made of 2X and 4X material. It's heavy and steady as wood can be. I wish we had concrete benches. My bags have different media -- I don't think any of it is sand, its different densities and sizes of plastic pellets. Some of them are so light they stick to things while others are heavier like rice.Let me ask about those fliers !! Are they random in all directions ?? Are they prone to be

I think so too. We get a lot of windy days here, but luckily most of the time it blows in the direction I'm shooting. It still pushes me from behind though. I'm definitely my worst enemy when it comes to golf. It is a lot like my shooting, if I could just get rid of that one shot......Groups aren't that bad.
