Re: Cold bore shooting/ Clean barrel
Here's something you can try. Get a hold of the most concentrated isopropyl alcohol (meaning the highest percentage...I can't find anything higher than 91%) and the next time you clean your gun, leave it that way and take it to the range for a test shoot. Prior to firing with your perfectly clean and oiled barrel, clean the bore of whatever you use for storage with your solvent. Dry patch the solvent out then run a couple of patches of the alcohol followed by dry patches. Then test your zero from a clean cold bore.
A gunsmith told me what the real issue with 'fouling shots' is not that the rifle prefers to be dirty, but even after dry patching out the preservative in a bore, there remains a residue that will affect the internal ballistics until it is all burned out. Coincidently, the barrel is now fouled.
I've tested this with a few different percentage levels and the purer the alcohol, the tighter my cold bore zero was. The other 9% is additives which would likely interfere like any other type of oil based preservative.
I've heard nearly everyone claim that a dirty barrel won't harm your rifle, but I've spent too much coin on my custom made system and I have a difficult time accepting leaving my barrel fouled is 'good' for my weapon.
Run as fast and as long as you can... my little friend
will catch up and set you free.
