.22 LR conversion kits. Are they safe?

[Suwannee Tim]

I think if you are diligent in looking for lead and maybe even running a patch down the bore to feel for lead, if you are diligent the chances of damaging your barrel are very remote. Good 22 barrels shooting good ammo don't lead. The risk is in copper fouling that disposes a barrel to lead, then you don't see said lead, go back to 5.56 and OUCH!

I think we are saying the same thing.

Yeah, except I would not shoot a jacketed bullet over any lead. I don't think you really can tell how thick it is by looking and I think even a little bit of lead causes a little bit of damage.
