I had a CZ452 with a squib round jam in the barrel which I didn't realise at the time, fired another one down and the stock blew up in my hands scattered all over... Edgar brothers replaced the stock and some of the trigger guard area, said the barrel was undamaged.
This was using the old Hornady blue tips which they recalled... I've not had an issue since, just the occasional no fire from winchester ammunition ... the new hornady and federal are spot on. I love this round, its very flat shooting for NV/Thermal vermin control out to 150yds and requires minimal reticule holdover out to 200yds, I did try going down the .22 hornet route but its a pain in the arse reloading in any sort of number when your going through 50-100 a night... local store stocks hornady at £13.50 a box so its so much easier than all the reloading in this case for me...
