Can anyone compare/contrast the Chambers' Whitelighnin' ventliner with the RMC allenhead touch hole liner?

Is the performance about the same or is one superior to the other? The looks of the allenhead would take some getting used to but if it performs . . .

THANKS IN ADVANCE

I have heard the Chambers is the best thing around, I do not like the allen type a lot of corners to catch residue....having said that I have found a fair size plain hole coned on the inside do be as fast as I need.....as did the majority of original shooters.

The Allen screw type I hate and have thrown them all away. I use the White Lighting liners in everything I have. I open the hole to 1/16 and cone the outside at the same time. I load them so that I have a kernal of powder peeking out of the hole at the pan and they go off like a cap.

I like the Stainless Steel and fine threads on a Chamber's liner. It's hard, not going to rust and the finner threads would seem to me to be a stronger conection than regular threads given the amount of coning on the inside which results in thinner walls.
I don't know about the RMC but the White Lightning is hard to beat.

Just my opinion.

Squeezebox,

Here is the real deal about vent liners. The white lightning might be a little bit faster, but not that much faster that the difference can be discerned by the human mind and ear.

The difference in ignition time between the WL and other vent liners or even a simple drilled and chamfered vent hole is in MILLISECONDS and is imperceptable to the human ear.

In scientific tests the WL vent liner is more consistent in that the ignition times of multiple ignitions are closer to the same time than multiple ignition times of other vent liners. This doesn't mean that the other types of vent liners have more misfires, but just that the ignition times vary more. The varience in ignition times with the other vent liners is, once again, in small amounts of milliseconds.

I have flintlock guns with standard 1/4-28 vent liners, 1/4-28 vent liners that I have cone out the back side before installing, stainless steel allen head set screws and a few with simple drilled hole vents. They all provide consistent ignition and since any ignition time is in milliseconds it doesn't make much difference which type vent you use.

If someone is experiencing misfires it is easy to blame it on the type of vent, but I always suggest that the vent hole diameter needs tweaking or there is some other problem with their loading and shooting process not the actual type of vent used.

I don't know who makes them for TC but their's are outstanding...I've put 7000-8000 shots through 2-3 of them and ignition seems instantaneous each and every time.

Huge hex well on the outside acts like a large funnel, and has a bevel on the very outside edge leading into the hex well itself.

Then there's the large well leading in towards the hole.

Then another bevel at the bottom of the hex well patering right to the edge of the hole.

The hole is huge at .075" (just under 5/64") and the stainless wall it's in is about .030" thick.

Then there's a huge cone inside that brings the powder right up to the vent hole where you can see Goex 3F perched right there.

An extremely fast, clean vent...I don't know if it's because of the patent breech of the vent design itself but it's apparently self cleaning as it never gets dirty and I never use a vent pick...no longer even own one...100% outstanding vent liner used by TC.

I have never been happy with any of those liners. I buy the Treso Ampco liners and then modify them myself. I get the best results that way.

When you say "those liners" it sounds like you're referring to all the hex liners as a group, implying they're all the same and they are not...designs and specs vary all over.

I don't know much about 'those liners' or 'other liners'...speaking strictly about the ones TC introduced about 6 years ago...their design is unbelievably fast...by contrast, when I buy a GM barrel, I unscrew their hex liner and throw it in the trash...replace it with a TC.

I to have always used the Treso Ampco torch hole liners...Like the way you end up with a flush mount at the barrel flat and can be taylored to fit any barrel wall thickness...Your not going to be taking it out till it wears out and then it is easy using an easy-out...No liner wears out before a few thousand shots in my experience...

Why would anyone want a slot or hex/allen installation, unless you are taking it out to clean which is unnecessary...

Don't like the slot/hex business showing above the pan when the frizzen is closed, just another way to get moisture in and priming powder out and it looks pretty 21st century... ...The Lizard...

I've used both, with good results, providing that
the touch hole diameter is big enough. The only problem I have with the White Lightning liner is the thread size which prevents you from easily
using it to replace another type, or convert a percussion drum barrel to flint. As an example, I bought a partially built .72 cal percussion rifle with a Siler lock from a guy who lost interest in it. It took five minutes to swap a Chambers flint Siler and RMC vent for the percussion setup. I really didn't want to bother with drilling and tapping for a larger Chambers liner. The RMC works great, after enlarging the touch hole.

I have the white lightening liners on two flintlocks with large Siler locks. Ignition is very fast. I installed the RMC liner on a 40 that I converted from percussion to flint. It uses a liner with a 5/16X24 thread. I was not happy with the screw slot liner so I tried the RMC. I like the RMC, but I don't think ignition time is as fast as the rifle and fowler with the white lightening liners. The 25 year old Cochran lock may make some difference in speed.

I spoke to Jim Chambers about a WL liner for the 40 cal. He said it would not be safe to install because of the difference in threads. I don't think it is worthwhile to weld the existing hole and then install the WL liner, so I'll live with the RMC until a 5/16X24 WL liner is produced.
