My dad gave me a 308 rotary magazine 99 that was a bad luck charm for me. never saw deer with it.
I picked up 300 savage that I took a few deer with and think its about perfect except for ammo cost and lack of availability... foolishly sold it during the ammo shortage when I thought I needed to reduce m deer rifle count.
Sold an inherited well worn 3030 that was beyond repairs, but still shot. It was really ugly and abused with a dark bore, but it would have killed a deer. Gunsmith friend needed parts and should have kept it instead.
Found a steal on a 99c in 308 with a cut down stock recently. Will only sell it to a kid in need. Like my rotary better and I've started to carry it more because its luck has changed. I like it because its the only 99 in deer camp.
I generally don't regret selling & swapping guns, but the 3030 and 300 are two I should have kept. 99's are just too cool.
