Hi Nick.
Part of the design brief of these slugs, was for the slug to be able to expand on impact, when shot at sub12 velocitites.
They do, so I'd say that makes them safer, in any hunting scenario, than popular pellets like JSB heavy / Hades which don't expand and give far more pass through.
There will be further reviews of these coming shortly, which will hopefully confirm the above
Benefits of a slug design, incude a far better BC than a waisted pellet of similar weight, and an ability to be less affected by wind.
Who wouldn't want those advantages, either for comp shooting or hunting ?
