I find the Hornet has much less muzzle blast than a .223 along with less recoil.........half the muzzle blast IMO. Definately more than a 22wmr but much less than a .223
My Handi Hornet shoots about m.o.a. 5 shot groups with factory ammo. IMO, thats certainly plenty of varmint accuracy for it's couple hundred yard varmint hunting range. While some .223 (along with a few 22 Hornets on here) apparently approach half minute of angle accuracy with 5 shot groups. As an avid varmint hunter, I would not even look for ".5 moa" until shooting varmints in the 400 yard range. Even so, once past 400 yards I find judging range,wind,come ups,knowing actual trajectory,etc. likely more important than the added 1/2 moa of accuarcy for field shooting rather than bench.
I have never owned a true 1/2 MOA rifle the closest I have owned is in the .6's-.7's for 5 shot average not best.
I guess my point is the Handi Hornets shoot very well.............plenty well for their range and I prefer less muzzle blast,re-coil for my type varmint hunting .
