DavidS -- Thanks for the suggestion. For this last video, I started the day with a clean bore and the Federal Premium ammo, which doesn't have much wax on it. After the 20 rounds, I didn't touch the bore, and switched to the SK Rifle Match. I think the bore may settled after less than 10 shots. The problem with concluding this is that I was mentally still a little ticked off that the Federal was so bad, so it may have just been me throwing the first few shots until I settled down, not the bore!
So far, it seems the MTR only throws one or two shots out of the first 10, clean bore or dirty, warm or hot, but I still haven't concluded it isn't just me. The difference between me doing things right mentally versus some complacency is evident in targets 9 and 10 in the latest video above.
Now the Savage would throw shots 4" in any direction for 30 rounds before it settled down to 2" groups. That was terribly frustrating. The MTR is definitely tolerable cold and clean as well as cold and dirty.
Now that I am in a humid climate and have seen the pitting in my P-09 barrels from not cleaning regularly, I am much more careful to run a few patches then an oiled one in all of the barrels after getting home, just to minimize the chance of pitting the new "good" barrels. I'm also very wary of any carbon ring in the chamber area. That was another real problem with the Savage. The MTR cleans up very quickly after a 100 rounds or so, compared to the Savage, one or two wet and 2-4 dry patches, then a very light oil patch, done.
