Hi Tom,
There are three classes, scope, open sights, and tang sights. 
It looks like the Summer Relay will be starting July 13th

One time me and my first wife were out in the pickup looking for Coyotes. We spied one way way out there. We got to wondering if we should take a shot. The wife said go ahead, take a shot. She said theres no way you can hit that Coyote at that distance.. I aimed what I thought was about ten feet over it's back. I had a new Remington 540 SS rifle. I think thats the correct model number. 541??  Anyway, I let go with the shot. We waited what seemed like  long time. Finally that Coyote jumped in the air and seemed to turn a complete revolution in its own hide. When it hit the grown again it was off on a dead run. That's when we noticed it was the neighbors Irish Setter.  We resorted to the ( dont ask, dont tell ) policy.  It was way way way out there. It looked like a Coyote.  It did.

I don't usually get to shoot the rifles I work on at targets but there was this one that came back. Customer complained it would not shoot so I mounted a scope on it because of my tired old eyes and proceeded to the range. Sure enough it did not like bulk Remington ammo and had close to 3" group at 40 yards. I was not to happy but another smith told me that the ammo might be the problem so I ran some CCI standard velocity through it and all the holes were touching at the same distance.  Most of my customer say the liners shoot great, the rest don't say anything except the one that came back for not shooting good.
Shooting a 22 at 300 yards sounds like fun. Probably compare to shooting muzzle loaders with round ball at 200 yards. Only the ones who practice hit the targets.

      First let me say that it's never been confirmed that T.J. makes the hammer forged liners that are marketed by them.  The equipment to manufacture hammer forged barrels and the thin walled liners is something that is not easily acquired.  Essentially it requires a series of hammers to produce such a product.  Perhaps, T.J. makes the mandrels which are then forwarded to some third party with the very expensive hammer machine.  The British company Parker Hale had the equipment, again the extremely expensive hammer forge machine, with which to produce hammer forged barrels and used these barrels extensively on their Enfield, Volunteer, Gibbs, Whitworth, and other period muzzle loader reproduction rifles and carbines.  P.H. eventually sold off the hammer machine to another manufacturer and discontinued those very fine and desirable British manufactured reproductions, never to be seen again as new production, except from a Mediterranean country want-a-be.

Yes, T.J.'s Enterprises has an extensive listing of calibers of barrel liners available.  You spoke of the 32-40, but of course there is no chamber in the liner, that is done with a chamber reamer in conjunction with the installation of the liner.

 It has been a year since I acquired a T.J's liner but the current pricing for Retail customers, the price is $4.90 an inch plus shipping and some uncommon sizes sell for $5.50 an inch plus shipping, then add the labor costs to have it installed, fitted up, and chambered.

Thought I would straiten things out a bit. T.J.'s does offer a 17 cal., .168" bore .172" groove, 1 in 9 twist, 3/8" OD.  This has been listed on there sheet for several years and I have installed more than a few. Latest price I have listed is $3.95 per inch, ( 22 cal 5/16" liners are $2.60).   I have done business with them for quit a few years and several times the hammer forge was going when I called, could hear it going over the phone. The hammer forge machine, from what I understand, belongs to a partner.
T.J.'s is a little higher priced than Redman, you get what you pay for. As for me I quit using Redman liners a long time ago.
T.J.'s has a very good selection of liners. I show two liners for the 32-40/ 32 special, 1 in 14" and 1 in 16". Also a 32-20 liner.
If I were to install a liner for you the cost would be $220 to $320 depending on length and caliber, plus return shipping. A Stevens favorite would be $220 in 22 cal.

Will the #4 remington rb handle the 17 cal? Your personal opinion. Is anything different about installing the 17 compared to the 22? 
Thanks for your expertise.

The pressure on the modern 22 LR high velocity is the same as the 22 mag, 17 HMR and 17 Mark ll at 24,000 psi, sammi specs. If your #4 is in good shape it should be fine with the 17 cal.
The 17 cal. liner is 3/8" diameter and works fine in every rifle I have used it in except the simi auto. It seems the pressure curve is different and the brass will bulge at the base with a floating breach block. Seems strange but the cure is drilling a few holes in the breach and filling it with lead. This is not adding much weight but deadens the bolt sort of like a dead blow hammer. I'm sure the factory 17s are not using lead but are using a different alloy with different springs.
