I'll not repeat the stories but at least 6 people who currently post on this forum have personal experience here..... someone may mention Pat Byrne..... others will tell as how they watched a guy at their range get carted away to have the extractor removed from his face......
Many will tell as how knowing the danger they've gone ahead anyway...
Several action builders I know will share as strong an antipathy as Dan.
One in particular will get even more vocal than Dan, citing multiple instances.
I'll not enter the fray as I believe helmet laws and seatbelt laws are themselves a crime, but absolutely respect Dan's perspective.
There's a reason Sako bolts have a sliding/rotating shield in place to block the extractor from floating out and sliding gently through your optical meatus to rest beside your basal ganglia
((here's where Dr Tim can hop in and say "you stoopid"..... "extractor will NEVER make it past the superior rectus!" ..... too much fluid and dense tissue for an item of such small mass and sectional density at that velocity"...... "it'd most likely find bone, glance tumble and/or jam sideways and come to rest somewhere's in the vitreous humor!!".... )))
edited to add that BTW I don't give a rat sass about what Pete hissownself does here in terms of safety....I'm unpaid to teach safety professionally in several venues and paid to teach it in several more but most people don't learn that way. IME giving people the tools with which to harm theyselves is the ONLY way for society to evolve properly and that while I profess to be "The Safety Geek" my safety lectures only occur once. I'm that guy who has actually paid the hospital bills many many times for many many people who were warned once.
