Remington started cutting off the little flag on the safety that locks the bolt. This was done beginning in the early to mid 80s I believe. This was done so the action could be opened while the rifle was still on safety. I, like you, hate a non locking bolt.My $.02. I’ve probably owned 6-8 of which at least 3 were ‘06. Only 2 now with 1 in ‘06 and 1 in 222. They all shot extremely well occasionally clover leafs...but my number 1 gripe is some of the bolts lock closed in safe position and some do not! I hate the ones that do not lock! Several times I have had my rifles slug on my shoulder, rushed to get into position for a shot only to discover the bolt had come open and the cartridge fell out somewhere down the mountain!
Just a dislike of mine. No clue why some do and some don’t and I haven’t found a fix for it yet.
I also agree with everyone’s thoughts on the redundancy of the 30-06 and 300 WM. Even though I too own both, I wouldn’t take both on a PG hunt unless there were two hunters.
Best of luck deciding what to do!
The cut out in the bottom of the reciever where the flag went through was still on many receivers to come, so if you had a safety with the flag on it laying around, it was a simple fix. Now they don't even machine that slot out anymore. I would be willing to bet that this 1986 rifle at least has the slot cut, but may not have the locking safety.
