Late night in the gunroom..
Three brief topics...
1. Cleaned the SubMOA barrels in the last 30 minutes and found only one teeny tiny sparkle of lead on my patches. Used the same process that was before, stripping out a fair amount of lead sparklers. The barrels each have had a couple hundred shots since last cleaned. Weeks ago I polished the 1:22, but the 1:16 is still as-received. I think the reduced lead buildup is from shooting EVERYTHING that goes through the barrel, generously lubed up with Gunzilla. From about 5 years worth of examples of witnessing that agent's ability to reduce or greatly slow down lead adhering to the barrel, I'm not surprised. And glad to see it helping immensely with the leading up of the SubMOA barrels.
There's always some chicken or the egg when running experiments like this....in this case, have the SubMOA barrels become "seasoned" and aren't grabbing the lead as much because of that? or in the case of the one I polished, did that make the difference? Or is it the lubed projectiles that I switched to making the difference? If the 1:16 was still leading but the 1:22 wasn't, I would conclude that the polishing of the 1:22 is why it quit collecting lead in the rifling. BUT, because even the 1:16 that I didn't polish is collecting much less lead, I'm leaning towards the difference being the lubed projectiles.
Testing is ongoing of course, but at this point, I'd recommend lubing projectiles that will be shot from SubMOA barrels. Gunzilla is working for me, but other agents may achieve the same benefit.
2. Tomorrow's weather forecast is looking good for some shooting. If all goes to plan, I hope to...
3. I was lent a bore scope from an airgun buddy. I've spent a couple hours, a couple different times, trying to get it to work with my phone. It's the kind that uses the screen on the phone as the image viewer. I'm fed up with fighting it, and will no longer be messing with it. It's in the "pellet sorting" category for me now, ie, I'd rather eat horse manure than waste another second on it. Okay, hyperbole....much more realistically....I have limited airgun time, and, as much as I'd like to inspect the bores, shooting is just more fun that fighting that dang bore scope anymore.

- run some more of the 12.5grain NSAs through Rudy's barrel with current settings, on paper at 50 yards. The idea here is to verify that that last 0.8moa group from it wasn't just a fluke or an outlier.
- bump the reg up from 130 bar to 140-150 bar and run some of the 36-40grain slugs through the 1:16 barrel on paper @ 100 yards.
- degas, drop the reg down to 70-90bar and start dialing in on a sub20fpe tune for pellets with Rudy's .177 barrel.
