Unbelievable! These babies are top notch, when it comes to premium hunting slugs. Hitting power is maximized with these babies having such a deep hollow point. They also fly incredibly well out of my Huntsman Revere. Consistently landing dime sized groups at 25m and 1.5-3” groups out at 150m, which is impressive for such a heavy gr projectile out of my max 950fps rifle. I’ve been very impressed with these other than the price point at which I’m required to pay for these devils. However you do get what you pay for, they’re clean, polished and more uniform than NSA. However they fly just as consistently as my .217 17.5gr NSA HP but hit with for more energy.

I used the FX Hybrid Slugs in my Daystate MK4 Si .22 with a Heliboard I got 10 shoots under 1/4" C/C at 40 yards. I have tried JSB's Knock Out .216 and .217, Nielsen's 23G and H&N .217 and .218 Samples kits and nothing came that close. The price you pay to get accuracy.

My FX Royale didn't like it. 1.6 inch group is typical at 50 yards. Very disappointing.
