Good article here on the WSTIAC Primer Study on lead free primers. The article link was originally posted on the FB list by R.G.C (Many thanks Robert) which is where I saw it.

It makes for very interesting reading, key Findings of the WSTIAC Primer Study Were:

It makes for very interesting reading, key Findings of the WSTIAC Primer Study Were:
1. Lead-Free primers suffered from significant delays in ignition.
2. Lead-Free large rifle primers had a “a much larger variation in peak blast pressure” than did lead-based large rifle primers.
3. Field tests showed 7.62×51 rounds loaded with lead-free primers to be less accurate than rounds loaded with lead-based primers.
4. So-called “match-grade” primers were NOT always more consistent in pressure than standard primers.
