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.

A friend moved and gave me 2k lead free SPP that I promptly chucked on the shelf. I ran low on my usual stuff so I decided to try the lead free for my practice ammo. Stovepipes everywhere! Nothing changed except the primers (38Super loads). I didn't expect them to be great but the proved damn near unusable
