If you’re not hunting with a rest, you probably don’t need a rest for zeroing. You can shoot from prone, a range bag from a make-shift bench, or a log or whatever, for zeroing. Shooting over the hood of your vehicle can work well too. Just understand your sight over bore distance, so you don’t shoot your hood.
Bore sighting is altogether optional. I’ve sighted in dozens of rifles and only boresighted once. That’s more for installing a custom-made mount, where you have to get it aligned with the rifle well enough that your optic won’t eat up its adjustment just getting a zero. If your rifle and mount were properly made for each other, starting out at 20 to 25 yards is plenty good for getting on paper. Then you move out to 100 or 200 yards or etc. FYI: the worst time I ever had getting on paper was with a guy and his new rifle. The rifle had been “bore sighted” at the store, so he didn’t want to start at 25 yards. After failing to spot several shots, I noticed his rounds hitting 5 feet to the right. (OK; at 100 yards that’s 60 MOA. WIth 1/2 MOA clicks that’s 120 clicks left). If you can remove the bolt and look straight down the bore, OK. But make sure you’re looking straight down the bore.
