Lead free primers

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:

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.

I read the report and found it interesting. The one thing I took away from it was different primers can make to seemingly 2 identical loads but using different primers. Certainly something that I will play with in the future - taking into account that different primers can create higher pressures etc.
