Re-lube old rimfire ammunition
I clean off the old dried up lubricant with a little Hoppe's No.9 on some tissue, wipe them all off again with clean tissue, then apply 50/50 beeswax and mutton tallow with just a half BB size bit on my fingertips.
I picked up about 250 boxes of Eley, Lapua and R-50 that is probably 30+ years old. At first I thought it was corroded, then realized that the lubricant was just really, really dried out. On one of these forums I found a string of questions and answers like this; best was the observation that Eley advertises their lubricant as beeswax and tallow.
I ordered beeswax and mutton tallow from CVA black powder supplier. Checked melting temperatures and slowly did the 50/50 mix on the stove top. Filled one pellet tin that will last forever. Knife blade to scrape up little pieces and apply with my fingers, it gets pretty soft just from finger temperature.
Recliner chair, movie, cloth towel and five or ten boxes at a time (fingers get a bit tender but not bad). It really does go pretty fast, but I spend more time in the recliner chair than I do at the range anyway.
This old ammunition is by far the best I've ever shot in the Anschutz. No way I could afford this much top of the line ammo, I'd still be screwing around with CCI standard and Federal 711 and wondering what I was doing wrong all the time if I hadn't tried this old high end ammunition: not a single FTF or flyer and group sizes are less than half.
I know this would not be usable for competition, but from what I can tell it is just as good as some of the new Eley Tenex and Eley Match I have purchased recently.
Hope this helps, I do see bunches of old match quality ammunition for sale on various websites. If the price were right (half price or less) I'd probably give it a try.
