Verry interesting. The hammer is keeping pressure on the bolt so the bolt is in contact with the receiver. It would not take a lot of buffing to make the relief.

Perhaps more than buffing. I think you'll have to file a 1/8" notch.
It does NOT need to be full width of the bolt though, because the hammer isn't as wide as the bottom of the bolt.
Also the top of the hammer might be relieved a bit too. It just has to contact hard enough to cock, but the bolt pushes it somewhat farther back than that.
Were those lines close to the muzzle, close to the breech, or in the middle?
"..........the rifle seems to prefer a slightly soiled bore".
That statement is very important. For years, shooters have been oiling their bores with Ballistol after cleaning. When you wipe it out, prior to shooting, it acts like fouling to give a more consistent POI, especially with the first shot. That is, the first shot is not so much of a flier and is closer to the group made by following shots. It is not AFAIK, a long term rust preventive. We shot weekly and it was more than sufficient in our humid, salty climate.
The JB will be Difficult to remove. I used to go to extremes to avoid leaving some in my precious bore In truth, plenty of solvent (Ballistol too), lots of patches and bronze brushes to scour the stuff out of the corners of the rifling is the way to go but I freely admit to boiling out the barrel just in case it got in to the "pores". I never minded all this rigmarole but I would not blame anyone who did. I suppose you could say that I never liked leaving anything to chance
Good luck hombre. Hope it all goes well and look forward to your results.
"For years, shooters have been oiling their bores with Ballistol after cleaning."... Never heard that but makes some kinda sense. Now you have me wondering about EEZOX and Frog Lube, which coats the surfaces a bit. I wonder if that will help. I know about cleaning with alcohol to get all the oils out. I have both products so now i have to decide which to use after I shoot a few out of a spotless bore.
OH!!! Someone sent me a link about a cheap bore scope that works. Amazon has some 5.5 mm scopes and also ebay.

This could be fun. I also found chore boy copper scrubbies on Amazon which are all copper and very useful for lead removal from your barrels.

PS I didn't have any problem getting the J-B out of the rifling. Using Kroil oil seemed to flush it right out with 2-3 wet patches.
alcohol
After using methylated spirits (denatured alcohol?) to clean out rust preventive oil in the bore, results were pretty nasty for the first 2 or 3 shots at least. After you wipe out the Ballistol with 1 or 2 patches, some of it is left behind. That "residual" is what acts like fouling, to reduce the first-shot-flier.
Since reading this thread I've been much more careful about cleaning the bores, as I do shoot lead all the time.
Also I noticed that my Henry 357 lever rifle has a relief under the bolt when you cock it all the way back.
It happens to be right where the two piece firing pin meets. The design is considerably different than the Mossberg or Winchester 94 in that respect. And of course the tube loads from the front.
So far the AR-15 has not been my most reliable gun.
I've managed to jam the magazine, and I've bent the bolt catch twice.
The adjustable buttstock is too wobbly for accurate shooting.
It shoots fast as hell, however, and rarely jambs or fails to fire.
The range officer had to chew me out for shooting too fast.
I am still slogging away at my long term project but still managed to get my rifle to a smith, who replaced its hammer spring. Have not had a chance to try it out yet. You might recall that my fore arm was taken off for testing with pretty bad results leading me to wonder if the stringing has been a result of the hammer spring all along. Only testing will tell but the project has priority.
Just a wild guess from me hombre but you might find a complete strip-down on you tube. I have done this kind of thing on another make and it was not easy, so I don't blame you for being cautious. Having mine done by a smith cast $116 for the spring and labour plus $50 for petrol You can buy a few tools for that money.
As for stretching the spring, that is something I have never done. I would think that you would want to test the original spring before replacing it but have no clue about that. BTW, my smith checked firing pin protrusion and very importantly, the timing of the locking bolt # 58 which houses the firing pin striker #59. These complexities are beyond me but now it is no longer a cheap gun. In the end, I opted for the peace of mind provided by a competent smith.
Best of luck hombre, thanks for the post about Paco and one day, I will be in touch.
