Got it. Appreciate the background info. To be honest, never paid much attention to the reasons behind the ingredients in Paul's lube. All I knew was that it worked in my Shiloh in pretty much any temp. My bore was a two wet patch and one dry and it was clean at the end of the day.
Back then there was also an standard opinion that no petroleum based oils/greases belonged in BP lubes. I think part of that stems from BP lubes originating before we discovered oil and the use of stuff like whale oil and such at the time.
I first came hear a year or so ago, maybe less, to learn about lubes. It got rather complicated fast. I have many sticks of Paul's lube that I made, but was not happy with it oozing out at the bottom of the bullet in the sizer and having to clean off the punch die and wipe the bottom of the bullet off. Never had this issue with that big 530 gr Paul Jones Postell. But then in talking with guys at the club, I found out everybody deals with this at the smaller calibers. One of the members here was kind enough to send some special waxes to me. I never did try to make a different lube. But I certainly have a reason to do that now.
By the way, Ric, that's a very nice group. Is that 100 yds. If that is 200, that's a damn nice group!!
Another incentive to change the barrel is to have more bullets choices at my disposal. The guys at the club probably own collectively just about every 30 cal mold known to man. Everyone is more than happy to loan a mold so another shooter and test some loads. I was on a quest to shoot longer, heavier bullets for better long range performance in the wind, but the recoil is more than I care to tolerate. I have a floater that is still partially attached to my retina and my Doc says no heavy recoil. He's a trap shooter and he quit shooting trap for that reason. So, I'm relegated to 170 to maybe 200 gr bullets for the time being.
By the way, I found two very good tutorials on the web for how to remove and install an 03 barrel. They differ a bit in technique. But otherwise are the same and very nicely done. One is a thread on the CMP forum by Chuckindenver, who I see is a highly respected milsurp rifle builder. I plan to call him today to see if I can pick his brain a bit.
