Believe it or not, I got hold of a box of these in .177 (for PCP) and we ran them through a gas ram break barrel rifle doing under 12 ft/lbs.
The group was astoundingly small, much better than the JSB's it usually shoots.
I also got very very good groups through the Steyr at all ranges. Downside was the trajectory was a lot more rainbow like, also at 12 ft/lbs.
If lead was ever banned, they could be used, it would just be "different".
