I currently use LBT Blue lube and I'm happy with it. Prior to using LBT Blue, I used the NRA Alox 2138F/beeswax formula. Recently, I've been reviewing the NRA Cast Bullet Manual and its comments on using straight lithium grease as a bullet lube. Apparently, before the Alox/beeswax mixture was developed, the NRA stated that lithium grease was the most accurate lube based on NRA testing. The NRA then stated that because lithium grease couldn't be used in lubrisizers, it use was dropped and the Alox formula developed. The NRA also stated the Alox formula equaled the lithium grease in accuracy. There was also mention of placing a kapok or dacron wad over a powder charge and then putting a few grains of lithium grease directly on the wad before seating the bullet. Accuracy with this technique was good and there was no leading. Some reloaders mentioned to the NRA that after eighteen (18) months these loads performed just like fresh loads, implying the lithium grease did not contaminate the powder. I assume this occurred because lithium grease is not sensitive to high or low temperatures. The NRA also successfully used lithium grease on paper-patched bullets.
On this website and others, there are simple formulas to thicken lithium grease with beeswax so that it will work in lubrisizers. Has anyone run tests comparing the accuracy of lithium grease/beeswax loads with loads using other lubes like the NRA Alox formula, LBT blue, or others?
