Gerard,
Thank you for your reply. I have also read your reply in another format and you stated that only one instance of an unexpanded bullet has occured.
Since that must be from thousands and thousands of animals shot it must not be any large concern. It was a theory of mine.
I see that you have a USA distributor and some bullets are in stock. I had not know that.
