JB Bore paste, Moly bore treatment & soft lead and slugs.

[MACTEN]

I've had really good results in the past using JB bore paste and then treating with moly bore treatment with my PB's..
Started doing it in pcp's as well and find this helps with fouling and accuracy as well. (I also lube ammo with slick 50 one lube in airguns)
But I'm wondering who makes slugs that aren't as soft as teh pure lead options I keep buying
Lapping the barrel and treating with moly helps a lot but it would be nice if more slugs weren't quite as soft. I know why pure lead is the go-to but I don't really hunt with airguns and just punch paper.

Un-lubed airgun pellets that foul the bore tend to contain a higher percentage of antimony. While soft lead will also smear off inside rough barrels, it does not "solder" to the barrel like high antimony pellets do. This is probably true for slugs also.

Your barrel prep and lube should reduce fouling, even with pure lead. Certainly, cleaning would probably be a matter of three tight fitting patches pulled through. Probably no need for a bronze brush.

You could cast some harder alloy slugs to see how they perform. One reason why I think sub .25 cal slugs are never hard cast, is that the bore friction can be so high that the slugs get stuck in the barrel. Obviously the relative size of the slug and bore, and the chamber size and taper have a lot to do with that also. With hard cast high antimony lead bullets, lube is essential to avoid rapid and excessive lead buildup in the bore.

What caliber slugs are you shooting?

I'm shooting .30 and .22 right now. I've lubed the bores for years but I hate fouling. I use more than 3 tight fitting patches but everyone has different methods they find work of course. I've thought about casting but don't need to add even more things to drink my time LOL..

You may find commercial lead cast bullets. Or, get some guys on AGN or GTA to cast you some airgun bullets in a harder alloy.

Where are your barrels fouling? All the way, or near the choke?

Update to my research on undersized slugs

So I had a good email correspondence with Nick from NSA ammo regarding undersized slugs, and perhaps consideration of swagging a slug in .221 since that's the groove diameter of the Lothar Walther barrels that 95% of gun manufacturers use. I explained the issue with air escaping around the...

Hard "slugs" and pellets

I hear a lot of people in the air gun world make statements about shooting harder slugs wearing barrels out rapidy. I even see comments about pellets having a bit of antimony worry about wearing barrels. I have a decent collection of century old powder Burning single shot rifles from before...

None right now. The Vulcan started to at first but I did a moly treatment and it went away. AVS 3063's. I just don't like having to do all the prep to keep it from happening. I'm not just doing a short scrub but work the bores very well sometimes taking hours of slow deliberate movements.
