Thanks for the tips and confirming that these straighteners have a fixed position for the pins.
When I say the 6502 is "loose" I don't mean it falls out, just that it slides into the socket a little too smoothly: I would normally expect a bit more friction, not to stop it falling out, but to get a good connection, and I think that's what's going wrong here.
Typically I do something similar to what BeebMaster does: I tend to just get the pins aligned enough with each other that they're going to fit into the holes, then bend the pins in a tiny bit to give a snug connection onto the inside edge of the holes, so when I fit in one side, I have to push against them slightly to get the other side in.
I hadn't thought of Dave's suggestion that the turned pin holes might have actually shaved a bit off the pins in the other direction, and that might be why they're not fitting snugly. Of course, that wouldn't give any problem with the socket on the main board.
The 6502 is, I believe the original one from the Model B back in 1984 (it turned 40 at the end of April, exactly 10 years younger than me, if the motherboard sticker is to be believed!) — I have taken it in and out, when I've had issues with the Integra B, but I wouldn't say excessively, but I suppose they're not really designed to be moved around that much.
I think, as everything seems peachy with the other 6502 in the Integra B, I'll just leave that one in there: if I need to remove the Integra B, I'll just put the original 6502 back in the motherboard. (This will, of course, be famous last words as everything is bound to work perfectly until I put the case lid back on!) If I start getting problems again, I might consider swapping the socket — I presume Ken had a reason for preferring turned pin sockets on there.
