White Lightning vent liners

[smoke]

Hi: Any builders opinions pro or con on the white lightning vent liners?

Best there is, don't use any other when I am using a vent liner.

The best available commercially.
Last 1/4" I used was somewhat loose in the hole. Tap created a little too much clearance.

So was it the liner or the tap or maybe the tapper   Did you go 5/16th then?  Or $#*! cut the barrel and rebreech her?

I don't think there is a better liner or one that is equal out there.  Stainless Steel and finer threads for added strength. 
You can get them in steel if the shinny liner is a problem for you.

I proofed it with 220 gr of FFF Swiss and two .570 balls, shot it for zero and called it good.
The tap was too big or the vent too small. I can't get tight tolerance taps in 1/4 x 32.
So generally I make my own 1/4 x 28 this allows me to regulate the vent size to the tap size and buy tight tolerance taps as well.

I looked for different H limit taps in 5/16-32 from McMaster-Carr, and they only have H3, which is standard fit. Not sure what that means exactly, but H5 is very loose fit, and H2 is tighter tolerance than H3.

The threads in the barrel will be weaker than the liner, since the barrel steel doesn't have as high tensile strength as the liner. You definitely want a good fit, liner to barrel.

Blah, blah, blah.

Liner is 304 IIRC maybe 303.
Yield is about 30-40K. Ultimate is 80-90K depending on the grade.
1137 annealed is about 85K and 50K yield.
All ballpark. Slight edge, maybe, to the carbon steel.
