One piece vs two piece bolts

[Mj30wilson900]

So listening to everyday sniper podcast I heard it is perfected to have a one piece bolt over the two piece designs. Is that because it is cheaper to produce a two piece so it is looked down upon compared to a one piece with exacting tolerances? Curious what problems have been had with two piece bolts besides braking off a handles possibly.

What was mentioned in podcast?

Two piece bolts that are brazed on have been known to come off with a little abuse like a round stuck in the chamber, mainly remingtons come to mind.
A two piece bolt that is properly tig welded no issues.
Its just a more cost effective process than machining them from one billet of steel.

So no accuracy difference?

Was the podcast referring to the handles or where the bolt head is brazed on?

Just my opinion but if it had anything to do with affecting accuracy i dont think TacOps would use them nor would LRI offer a service to time and tig them.

If it's brazed right you would have to really, really beat on it to break it loose and even then I think you'll break some other crap first. I think remington had a bad run for a while where the handles weren't done all that great.

Lri will time/tig the handle for a fairly cheap price if you are that worried about it.

This.

Bolt body separate from handle or bolt body and bolt head like savage, ARC, AI or other?

That I am unsure of. Frank was saying savage actions had their problems so he was saying a trued Remington action or many of the Remington 700 based actions are preferred.

There are so many of these points of view out there.... Once upon a time all bench rest rifles had to be single shot for the bedding area and increased rigidity. Then they came out with drop port and left load right eject actions.
Don't sweat this stuff, however I do like one piece bolt handles, floating heads etc couldn't care less.
However, that's just me.....

While I cannot comment from experience, for me, I will always choose a simpler design whenever possible.

Define simpler design? The Savage 10/100 bolt is 3 major pieces but they're all mechanically locked together, not brazed or welded. It's more complex in terms of number of pieces but they're each easier to manufacture than a true 1-piece bolt or a 1-piece bolt body with a brazed on handle. Simple designs are definitely something I prefer in technology and mechanical contrivances but complexity and component count are not necessarily coupled. You can literally beat on a Savage 10 bolt with a hammer and you might bust an extractor but you'll have a hard time breaking the handle, body or head. Do that to a brazed-on handle and it may just come off. Do it to a true one-piece and you'll not see a difference. To my mind, and folks are free to argue the point, is that the major benefit of multi-piece bolts are that those with floating bolt heads help to make up for some stacked tolerances like runout or offsets between the centerline of the bolt raceway and the centerline of the bore.

Same performance, less parts.
