I have never shot lead free pellets through any of my guns in fear of ruining any of my accurate guns.

I have spoken with a couple of shooters who primarily used lead free pellets who reported recently that their accuracy isn't as good as it used to be and their pellet fit into the leade is loose now.

This is only a couple of years of shooting lead free pellets.

Switching back to normal lead pellets did not help them get their accuracy back after cleaning their barrels and seasoning and still not as good accuracy as they used to be.

First question I will be asking when buying a used gun is if lead free pellets were ever shot in it before buying.

FYI

I find what you have described to be very-important to define and quantify, what with the possibility of such far-reaching and expensive ramifications.

I'd like to believe that the makers of lead-free pellets would have protected their customers from such problems when they were choosing substitute materials, but I'm afraid that my dealings with several companies and situations over the years--when big money is on the line--have left me somewhat jaded and skeptical.

I haven't researched the subject--at least not yet--but what you wrote, together with something I observed within the last year, suddenly turned-on a light bulb for me and has me wondering what the reality of the situation might be.

I have occasionally-used lead fishing sinkers in the past to weight air rifle stocks in the right places for better balance and accuracy.  I've always liked that they were fairly-easy to hammer into the shape I desired.  But some of the sinkers I received more-recently were much harder to shape because the alloy used was noticeably harder.  (Me: "???").  It was only after that, that I began to notice the "Lead-free" tags inside the plastic shipping bags in which the sinkers arrived.  The hardness of the material(s) being used, compared to lead, was very-different.

Could that same, harder fishing sinker material be related to the material being used as the substitute for lead in air gun pellets?  I think I will be keenly-watching how this situation plays out.  I'd hate to ruin a good barrel because of it.  And I feel sorry for any 'guinea pigs' among our fellow-shooters who shoulder the cost of providing the answer in the meantime.

I don't want to raise a false alarm here by my comments.  What I described regarding my experience with the new, lead-free sinkers may have no connection whatsoever to air gun pellets.  Maybe it will all be fine.

Safe and Happy Shooting!

Why do some airgun manufacturers state specifically not to shoot lead free pellets in their brand guns? I am sure people have already noticed the warnings from certain airgun manufacturers regarding lead free pellets.

I have shot quite a lot of tin pellets.

From H&N  and JSB (under the GTO brand). As long as the pellets are clean, lubed, and shot at reasonable speeds, there cannot be any excessive wear in the barrels. In SOME cases, it COULD be that the idea behind the use of non-lead pellets was to get into the hypersonic range of MV's, if that is the case, then there might be other factors bringing in a premature inaccuracy of the guns.

Please note that I am not disputing this happened, or that it could happen, just that there are too many variables to assign the loss of accuracy to a single cause.

Now, Nickel, Gold, Zinc and Aluminum are COMPLETELY different stories:

Aluminun is the result of electrolyzing a SOLUTION of Bauxite in Cryolite, there are very few commercial grade aluminums that can be guaranteed to be aluminum oxide  inclusions free. Aluminum oxide is an abrasive; aggresive, abrasive.

Everybody thinks aluminum is soft, and aluminum itself is, but in cheap aluminums, you will surely find some oxide inclusions and I doubt that Skenco uses the purest, oxide-free aluminum for their pellets.

If you doubt the quality of your aluminum, just try to scratch a piece of glass with it, If it gets scratched then the aluminum in your hands has aluminum oxide inclusions.

Aluminum oxide is almost as hard as diamond (9 vs. 10), so THAT COULD erode a barrel.

Gold and nickel also form crystals that could be abrasive.

The plastic carriers (not really sabots), of the aluminum/zinc heads may also be a source of barrel erosion, the electro-static characteristics of the plastic make it a dust magnet, and dust is made 80% of silica, another abrasive.

And Zinc dissolves steel. At the MV's that we use the surface temperature of the pellet could be enough to melt the zinc, that then will dissolve the steel it contacts.

It's tempting to lump all "non-lead" pellets into the same bucket, reality is that there are important differences.

As long as you lube your pellets and you keep to the maximum MV of around 875 fps, there should be no damage from pure tin pellets.

I would be interested in receiving data from the shooters that claim that non-lead pellets eroded their accuracy. If you can I would appreciate some contact information.

TIA!

I reached out to H&N about 10 years ago regarding this and they basically told me in a very short email that although their lead free pellets are hard they are softer than what good quality barrels are made of and don’t damage barrels.
