BPCR Lube.

At last week's range session, I brought the 40-65 out and 15 rounds of ammo loaded with 55 grs of Goex FFg and 400 gr Snover bullets lubed with Paul Mathews' "Premium" lube. Now, I know 15 shots isn't much of a test, but that's all I had!!
The results were very promising! I fired all 15 shots without wiping the bore or using the blow tube. There was no problem chambering or extracting the cartridges. The fouling was soft and easily removed with 2 damp patches. There was also a nice lube star outside the muzzle of the rifle. No loss of accuracy! I will try 50 rounds for the next test.

oldrodder, if did this over again with 15 cartridges and wiped between each shot with two patches what accuracy would you have? Better, same or worse than with no wiping?

When using Emmert's lube, I wipe after each shot, 1 patch, dampened with Moose Milk. I did shoot several 5 shot strings without wiping or blow tube with no appreciable difference in accuracy. My next test will be to shoot a 50 shot string without wiping. Then, I will continue testing as you suggest.
I would guess/expect, better accuracy with wiping. I should mention, in Paul's books, he says that he wipes between shots in competition even knowing that his "Premium" lube is capable of long strings with no loss in accuracy.

I put an extra long throat in my chamber so that most of the slug is centered /supported in the throat. When shooting with smokeless, that is not a problem but when shooting black, there is enough fouling in the throat to prevent me loading the next shell without running a brush down the barrel

I haven't modified any of my rifles. Planning on running my 50 rd test this Friday if I can get my ammo loaded !LOL!!

I didn't exactly modify it; I made the reamer to match my ideas on getting accuracy. I also bought a faster than normal twist barrel that I chambered to 38-56 I wanted to shoot a 300 grain slug to be more certain of knocking a ram over, assuming I hit one.

If that is the same rifle I saw you shoot up here, as I recall it did fairly well!:dancingbanana:

I went to the range today and fired my 50 rounds.
Loading protocol:
Unsized Starline brass, newspaper wad against the Win. LP Magnum primer, 55 grs Goex FFg, dropped thru a 24" tube over powder waxed cardboard wad, .250" compression done with a compression die, 400 gr Snover bullet seated by hand and a slight amount of neck tension applied using a Lyman .40 Cal rifle taper crimp die.
The shooting shack was full today, all 6 positions occupied so accurate shooting was a challenge! In fact, near impossible!

In conclusion, the lube worked exactly as Paul Mathews says in his book "Bullet Lubricants for the Black Powder Cartridge Rifle"
I fired 50 rds, 5 targets 10 rds ea. I had no problems chambering or extracting the empties throughout the test. About 1 1/2 hours to fire the 50rds because of other shooters needing to make the line safe to post or retrieve targets.
