Shotgun slug leading


Registered Users do not see the above ad.


We all know that factory slugs are not lubed, and foul the barrel. No one has really answered the question of why they don't lube them. Brenneke apparently says the ballistics are unpredictable with the lubes. I have been working on my own custom cast slugs for several years. and always lube them. Some loads have been pressure tested, and are consisent for pressure and velocity. The best lube, and the easiest to apply has been 50/50 Beeswax and lard with 1 ounces of Mica added per pound of lube. James Gates is using Moly, and has good luck. I think the Factory slugs should be lubed in the future. What do you think? Greg

With conventioanal Foster type slugs the leading is indeed severe. The best method for lead removal I have found is a 10 gauge cleaning brush wrapped with Brownell's 0000 bronze wool. I chuck the cleaning rod into a electric drill and make short work of it. Due to lead dust, it is best to do this outside. As the bore is polished by this method the leading decreases and the accuracy holds for a few rounds longer.

I too have used the drill method for lead removal. I gave up on Factory slugs, and cast my own. I developed my own load through trial and error, until I got a load that shot well, and had good performance. I FZinally had a 615 grain slug moving at 1555FPS from a 24 inch smoothbore barrel. Recoil is SEVERE. I have to sight it in with a sandbag between my shoulder, and the butt. I wondered why the factories would produce such a poor product. I worked for years on my slug loads, and been frustrated by poor accuracy. It took a long time to develop an accurate load. Shotgun accuracy is very unpredictable. Greg

ssotgun barrel leading

Just my thought bu I believe part of the problem is that shotgunn barrels are not as smooth as rifle barrels and that fact contributes to the leading problem anothe problem is that shotgun barrels are not made to the same tollerances as rifle barrels ammo manufactures have to consider this in design of the slug size that why buy different slugs and see which one works best.
