Medium-weight pellet, 0.65 suitable for powerful pistols and long guns
with 14 J the muzzle velocity is just over 207 m/s with 33 J it goes up to 318 m/s

stable trajectory, tight shot groups (better when keeping speeds just above 200 m/s)

  • calibre 4,51 very well finished
  • excellent ballistic coefficient
  • Considerable cost

I got these slugs to try them out. The point is to see if my air rifles will handle these pellets. I’m really curious about the result myself. Anyway, they’re all precisely pressed and don’t make your hands dirty. So the first impression is excellent.

  • I was really looking forward to this product so I could try it out. I hadn’t had Slávy 4.5mm at home yet.
  • When I see these cases precisely stamped like this, it’s a joy. I haven’t shot with them yet. I have to try them out. I believe they’re going to be great.
