I grew up with BDL's. Still have several of them. My 7mm served me well for years of hunting.
Then I started getting better hunting gear, boots, clothes, gloves, knives, optics, and getting whatever could give me any advantage in the field (even laser eye surgery).
Thought I'd try semi-auto for the advantages over bolts (reduced recoil, no operator error, reload with shooting hand still in place, reload still looking through the scope)
Bought every semi I could find at the time (all 30-06 even though I had always hunted with a 7mm) . Browning BAR, Browning Longtrac, H&K 940, Rem 4,740,750, Benelli R1.
For that last 5 or so years I've hunted with the R1 and haven't looked back. I take the BDL's to the range to dust them off, but when it come time to hunt for keeps, I want every advantage I can have.
And now that I am a semi-auto hunter, my hunting techniques haven't changed at all, I still don't "spray & pray", but if a second shot is needed for multiple targets, I'm ready.
And the vid of the guy with the bolt shooting pigs was great, and he's a great shot, but I wonder how many he'd get if he had a semi? I doubt any less.
