Seems to be a lot of controversy over the use of lead free pellets. Especially on springers. I just don’t know. Not to concerned though. I have enough lead pellets for my entire afterlife anyway. I don’t see any reason to try them. If a lead free pellet does indeed even microscopically round the sharp edges of the rifling it could over time then reduce accuracy. They need to launch a thorough scientific study. Give a 10 year old a springer and 1000 tins of lead free pellets.
Here is a couple interesting articles about springers and lead free pellets.
