What I would do…
Position the safe (and any pad or moisture barrier) and drill from the inside of the safe down into concrete. Over drill the safe floor if needed to clear the anchors. Bolt it down- no need to move or reposition. If you can bolt floor and wall its even better.
Use “gun socks” to prevent dings and scratches and alternate long guns muzzle up-muzzle down. I can get 43 guns in a 30 gun safe.
If the safe is on a wood floor with subspace basement or crawlspace, support it with steel underneath. I know of a guy that lost a nice collection inspite of his expensive fireproof safe, not theft or to the fire, but because the fire burned enough that the safe landed in a basement flooded by the firefighting efforts.
Use a golden rod or similar dehumidifier.

Haven't tried it but I think I could drop one mag and insert another without using my support hand for anything but holding the rifle without changing my grip on it. Topping off and reinserting reguires cradling the rifle in my left elbow or slinging it on my shoulder to use both hands to feed rounds into a mag. Picture doing this in the middle of a rock slide or while straddling a log.
I hunted for years with a couple loose rounds in my right front pocket and just made it a habit to top off after firing and ejecting empties.
Like I said, minor gripe- not a big issue.

At least I'm not alone. I will probably pick up a spare mag, but its too bad some design engineer didn't think of a staggered mag or maybe even an option for a fixed mag with staggered top loading. (Could have fit another round in.)
Oh well, certainly not a big issue or a deal breaker. Any time I've walked up on downed game, ie deer, elk, antelope, I've always approached with a full loading. I can't recall ever needing it, though…

Thanks for the good info.
I'm new to the tikka rifles and purchased a laminated just because of this issue.
Jason, if I understand are you recommending bedding the laminated stocks also?
