Not a question but just some info passed along;I'm getting ready for a club comp we've put up.Old time calibers(before 1900)shot with lead bullets.
I'm shooting many combos of bullets and powder and I think I've found my load(12.0gr Unique under a 350grLee pb cast unsized in 45-70).But as I was testing some more loads,I found that ''conditionning the bore''really works.I was shooting some alox lubed bullets with usual groups(2 to 2 1/2'' @100 yds).I then tried some alox/beeswax+gc bullets which didn't do so good.I went back to my usual(liquid) Alox lubed bullets and my first 2 or 3 bullets printed very high(4 to 5'' higher).
I repeated the test with the Sharps and then with my Winchester model 64 in 30-30 with again a prooven load(150gr Lee FN which comes out at 153gr lubed,mould beagled for .311'' sized .309'' gc +24.0gr IMR 4064).Same results;alox lube bullets following some gc loads printed hgh for 2 to 3 rds.
Conditionning a barrel with what you shoot is a true fact;like the song said;''now I'm a believer''!
I think that the liquid Alox lube leaves a film in the bore that makes the next bullet kinda glide into the bbl while clinging to the rifling and,if all else being equal,will group decently..Firing a few bullets with gc will scrape off the alox lube thus destroying the ''barrel conditionning''.
My theory, but am open to having it challenged by some other experiment that you might have found otherwise.
