Thank you, all the ways I googled it I could only find people asking about dud rounds. I have fired many thousands of rounds of .22lr and this is the first time that this has happened to me. I was using a bulk box of Remington Golden Bullet - high velocity ammo by the way... I was going to ask if it could have damaged the guns but you sort of answered that already... now, do you think I should take them to a smith or would you test them yourself with another ammo? There is no VISIBLE damage, as in nothing cracked or blown off but I dont want to have warped or stressed something important. One gun was a lever action .22 rifle, the other a semi auto pistol.
