You may remember in my post earlier about shooting my Pedersoli Frontier rifle up the cabin using my newly installed RMC vent liner. As mush as I like and prefer these liners for my T/Cs I had nothing but trouble using one in the Pedersoli. I had numerous pan flashes with no main charge ignition.
When I came home I checked the RMC against the original liner and saw that the RMC was at least 1/8" shorter. Because of this I had a lot of difficulty reinstalling the original as there was significant fouling in the threads and without the proper tap it was a tedious job getting the original seated. It took a lot of brushing with various size rifle brushes and screwing the liner in and out.
I took the rifle out today just to see if it was the liner and the rifle performed flawlessly. I fired 6 consecutive shots without swabbing and had zero failures and almost instant ignition.
I believe I will give RMC a call tomorrow and let them know about this issue as I'd much prefer using an allen wrench over a screw driver.

never liked that rmc line, to slow firing and as you said, the flash in the pans got sickening.

Jon - I did modify the original slightly by drilling a "funnel" in the face of it using a 5/32" bit.

That's weird. I have RMC's in three Great Plains rifles and all work flawlessly - way better than the original Lyman liners. A year or two back I had a .32 Pedersoli Froitier, also with a RMC liner that worked just fine.

I agree with Semisane. In my Green Mountain and T/C barrels as well as my Lyman, the RMC are the best vent liners I have. Real fast ignition, easy to get in and out with the Allen head on them.

Well guys I called RMC and told the gentleman my story and he really appreciated the feedback and was going to look into it. He said his dad had a Pedersoli flinter that he could compare his vent liner to.
I told him that I use his liners in my T/Cs and Lyman with excellent results but had a major ignition problem with the Pedersoli. He is sending me a new T/C liner as a replacement.

On a side note to this topic (and this is my opinion and I am not affiliated with him other than here) I used Jon's Frontier's Anti-rust and Patch Lube during the firing of these 6 shots. With no swabbing between shots the last shot loaded as easy as the first. Seems like a pretty good lube and will have to give it an accuracy test next time out.

That's what I used to do with the original T/C screwdriver slotted vent liners. I would take them in to work, chuck them in a collet and use a 45 degree spot drill to "funnel" the touch hole. Never had a problem after that but I switched to RMC liners after they came on the market and never looked back. T/C finally wised up and began offering their version of the RMC liner which works equally well but costs more.

Well I'll be darned. Guess what? I received my 3 pack of Pedersoli vent liners in the mail today and low and behold there was a recess in the face of the liners exactly like the one I put in mine! I guess the word went out.
I also just checked the flash hole and I could put an .060" bit into it so I would imagine it is 1/16".
