I intend to try that very thing in the summer heat this year Mr. Ben just cause i have a small batch of it made up. However the original version worked just fine last summer. Shot some of my tightest groups with it right thru the heat. No real reason to go any further with it really, i just like to experiment.
BTW i shot up to about 2600 fps. in the 35 whelen with 200 grain boolits and was amazed the bbl. was just as slick and easy to clean with just a patch run thru as it was at 1800 fps. Of course the usual.....no leading. If the 5% more wax shoots any better i'll let you know but the original does so well i'm not looking to gain much from it....We'll see.
