I have a .308 PSS and need to convert the bolt handle to a larger handle from the stock one from Remington. Anyone know of a company that does this without big $ and a six month wait? Thanks.

You don't have to "buy" anything. You'll think, believe, and do what is convenient, until through your own experience or the experience and knowledge of others you open your mind to new information.
Now, I never said that slightly rotating the bolt would <span style="font-style: italic">definitely</span> cause cartridge misalignment - what I said was <span style="font-style: italic"><span style="font-weight: bold">"Inadequate clearance may cause the shooter's forefinger to press upward on the bolt knob, which may in turn slightly un-seat the lugs.

Your assumption that <span style="font-style: italic">"solid machine work", "as on a 1/4 moa gun"</span> excludes the possibility of cartridge misalignment is incorrect. Again, there are other related factors involved, and you are just looking at a one detail of a larger picture.
If it pleases you to think that bolt rotation <span style="font-style: italic">cannot</span> unseat the lugs <span style="font-style: italic">"if the machine work is solid, like on a 1/4 moa gun"</span>, good for you. But to be fair, <span style="font-style: italic">if present</span>, very slight cartridge misalignment may or may not matter in a 1/2 MOA gun, as cummulative (stacked) machining errors may have more effect on accuracy than very slight cartridge misalignment.
For the majority of guns it probably doesn't matter. However, on Tac Ops guns, where <span style="font-weight: bold">each and every rifle must shoot .25 MOA or better before it leaves the shop</span> nothing is left to chance.
Take the time to read through and fully understand "<span style="font-weight: bold"><span style="font-style: italic">Tactical Operations Response (UPDATE - 1/22/08)</span></span>" in it's entirety. Some machining and procedural work is discussed, and I'm sure you'll come away enlightened about many aspects of Tac Ops rifles - how and when they perform certain operations, why they use a certain procedure, and how they consistently manufacture guns that shoot .25 MOA and under using factory Federal Gold Medal Match ammunition.

i have read that article several times and i must have missed where he mentioned that a trigger finger hitting a bolt knob could cause cartridge misalignment. i am not sure who you are but maybe you can answer this. what is mike doing to keep the sear from pushing up on the bolt? how much bolt body to receiver raceway clearance does he allow?

Nope, you didn't miss it in that write-up, but it is floating around somewhere on the web. I have a better idea though - why don't you call Mike at Tac Ops so he can answer your questions. Just call him up and tell him who you are, and as long as the answer(s) to your question(s) don't involve divulging procedures and/or techniques he considers intellectual property or otherwise proprietary I'm sure he'll be glad to explain things.
