Actually had this conversation with a ‘smith I use. He once measured every 6.5x55 he had in stock. They all measured exactly the same as the 30-06 etc bolt faces on any other rifle he measured. However that said I have a different shell holder in the press a no3 rather than the usual no2 used for 30-06 etc. But my Sauer 202 is designed to take anything from 6.5x55 to 9.3x62 (iirc) all on the same bolt. So I don’t think you have anything to worry about using a T3.

You could use a decent size penknife if you put your mind to it. However would you be entirely happy with presentation? Possibly not. There’s a reason why boning knives etc were developed to have different shapes and amounts of flex. That said you can manage with a decent size knife but it’s probably not going to be ideal

I used to work on a 24,000 bird poulty farm. As you can imagine we had a few rats. Bait is useless unless all other food is removed, bait only ever went after feed troughs were empty. fenn traps or nipper type work but leaving them unset but baited as already said is the way to go. What hasn't been mentioned but if still available is Tracking dust, a powdered poison. Rats are not the filthy animals most people think, they spend alot of time grooming. Which is where the Tracking dust works, you sprinkle it on the runs the rats ingest it by cleaning themselves.
