Torque Wrench for Prefit?

I have my barrels and bolts for my Impact action. What torque wrenches and barrel vises are you guys using? I want to buy a good one and I'm not seeing a thread on any torque wrenches.
 
I bought the like $15 harbor freight one and it seems to work fine. Doesn't need to be super accurate to keep a barrel on. I have the bald eagle barrel vice from grizzly and the viper is good too.
 
Viper barrel vice and a Harbor Freight 1/2" torque wrench I got on sale. I don't think it's "that" critical...
Its not

I use an old one from the 70s like this

But I also just dont use one more often than not now. Just make it good and tight until you go "ummph" and itll stay.

Edit: Ive found my grunt level like that is around 80 ft/lbs when using a foot long wrench/lever. With the half foot longer torque wrench its more like 100 when I grunt. So a good "ummph" will be fine in either case.

A Viper barrel vice and a Harbor Freight heavy-duty torque wrench work just fine for me. I also bought a long handle breaker bar for removal of stubborn barrels.

A related question is which action wrench do you use?

For example, I have Impact short action and Mausingfield long action wrenches.

Can I use the Mausingfield long action wrench for an Impact long action receiver or the Impact short action for an Origin short action receiver?

Thank you for the education.

Is a “grrgh” equivalent to an “ummph”?

You said good. Good and cheap are not synonymous when it comes to torque tools.

I use my Snap-on digital torque wrench and a SAC barrel vise, so I can test torque in 1ft/lb increments for best accuracy.

And?
Does it matter?

Do you know the accuracy of your torque wrench?

Has it actually been tested over its range of adjustment to verify it torques properly?
What's the +/-?

At what percentage on either end of the wrench does the accuracy fall off?

If you can't answer this, you're pissing in the wind at 1lb/ft increments.

So it's initial calibration from snap on, its accurate to +/- 2%.
That's reasonable.
No initial use date, no recent calibration.

It hasn't been dropped or rough handled I assume.

At 50lbs ft, going in 1lb ft increments, you could actually be torquing the exact same amount going up 1lb at a time or you could be over by 1.2lbs ft.

I think if you want to make an experiment out of it, you'd be better served with 5-10lb ft increments.

I'm actually very curious to see if it can truly make a measurable difference.

Factoring in shooter error, weather, component differences, etc, is it truly measurable?

I know the same type of experiments on reciever screws can show a huge difference in rimfire.

Man I hope you do find a torque value that is an actual sweet spot, vs 80-100 like a lot of people use.

I have a 6 PPC Benchrest rifle that can't tell the difference from 80lbs ft to just snapped in by hand.

Not saying you won't see a difference, it's just that my particular rifle/barrel can't.

If I get that desperate to further shrink my groups, please come put me out of my misery.
