Just picked up a new Field & Stream 260lb 10 gun dial safe a few days ago. Just got it unboxed and into position on the basement floor. Now, itsa time to secure it over the weekend. Never done this before and looking for any good suggestions on how to go about this. I believe my safe has 2 pilot holes at the bottom but I would like to add 2 more for extra security. Anyone have a decent, easy method for this process? I'm not sure what hardware, what kinda bit, etc. I'm fairly handy w/small jobs but never done this before...I wanna do it ONCE and be done with it! Thanks in advance!
