Does Eley ammo residue cause excessive wear on barrels? I heard this on some other forums.

You are possible mixing multiple sections of one particular thread together. The first part had to do with weather or not the current trend in barrels ( less invasive rifling) will or could wear out faster than conventional rifling. Answer only time will tell. The second part had to do with residue left in the barrel after firing and weather it was abrasive enough to cause excessive wear at apx 6:00, this progressed into a discussion on the mixture of current primer compound which includes ground glass. The same wear factors were seen in old barrels prior to the change. Conclusion was that at present it dose not seem to be a factor any greater than before.
Now for 99% of the population as long as they get minute of squirrel they are good to go.

Why would Eley use ground glass as part of their primer mixture. What does ground glass have to do with makeing the bullet go BANG. garrisone.
Garrison - in the new primer mixture it was necessary to increase the friction of the components at the time of firing pin strike to insure positive ignition of the compound.
The current compound isn't all that new been with us a while now.
Why powdered glass - dirt cheap.

Thank you my man for your reply to my question. don,t you think that over a period of time that this same glass will (-powdered or not) cause erosion of the barrel at the 6 'clock in a rimfire barrel and would this not cause the barrel not to last long? garrisone.

Garrisone, I'm with you on this one. Anyone with a bore scope can see what is happening inside their barrel. The 6 o'clock position looks like a gravel road after about a thousand rounds or so. I don't know how soon this will effect accuracy, but at some point one would think it has to.
All the stories about the rimfires that still shoot great after 40 to 50,000 rounds. Most of them were not shooting ammo primed with ground glass all of that time!
I surely don't know, but I'm not betting I'm going to get anywhere near that number of rounds thur my barrel before it goes south!
I've heard about Bob Barnhart's and Harry Deneen's barrels that still shoot great with many many rounds thur them, but I believe they are exceptions not the rule.

I think glass has been used in the priming compound for at least the last 50 years.

Tony, My 5R is showing less wear after 1 brick than any barrel I have owned

Mel that is good to know. I look at mine everytime I come back from a match and just cry!
James may be correct that they have used ground glass for a long time but I sure haven't seen wear this fast in anything I've had before. Who knows, maybe it's the steel???
