I've read Glen Fryxell articles,over and over through the years,great stuff.Just read his,what does lube do again.
Am not opposed to trying a different lube,heck it was you Fiver who told me to add more BW to my 50/50 lube(BW Vaseline) that has worked great for 40 years.But when the CDL '06 literally blew it right past the bullet at JB velocity and pressure. But that's a .30 and there's a lot more lube capacity.
The blow by don't really happen,as bad with jacked up 22-250 loads... to the point that 50/50 works,what little there is. BUT,that barrel had seen right many JB's and H380 in it's day. This new barrel and I,have not gotten quite to the velocity of the 250.... yet. But it is new,may make a difference?
I'm not really complaining about the fouling as it ain't, that bad. But at this stage of barrel life it may be at issue? dunno?
My gut says that if it isn't a rough bore condition,then it "might" be the Vaseline not playing nice.What can I swap out for it,and still be a two part,3-1 with BW? Some kind of synthetic grease?
