Anyone here using or have any experience with the pt&g dual pilot range rods? I like the idea, but I'm not sure I would gain anything over using my Gordy rod?
I like to indicate at the throat and 2 inches out in front of the throat. Looks like a good tool. Lee
 
OMG, I'm in sticker shock! You can buy a whole set of grizzly rods for less than one, caliber specific dual pilot rod! Then you need two sets of pilot bushings on top of that.

The range rods & grizzly rods operate on different principals, but I'm not certain either is superior to the other.

I can guarantee that a gordy rod is superior to a range rod. Like I said above, I indicate the throat and then again in front of the throat. The range rod indicates just in front of the throat " maybe, depending on how long the case is" and then back at the base where I am going to be boring metal away. no good in my opinion. I have used the range rods for crown work with excellent results, I must say.


I asked about this dual pilot only because, gordy rods can be a bit jumpy. Weight helps, and some barrels seem to indicate better than others. I already have two sets of bushings, and I like the idea of the dual bushing rod. I agree though, the price sucks!! Lee
 
I wish I could get Gordy rods with much shorter bushings...... I personally would have no use for any sort of double-bushed setup.
 
The Gordy rod...is that what they call grizzly rod? I have one in 6mm and haven't used it. How are you guys using it to indicate a chamber? Just stick it in and dial on the rod? I've heard of people holding the other end in the tailstock supported by an o ring and a weight on the rod? One or two indicators on the rod? Use both spiders to dial?

I've just been using a long stem interapid to dial throat area. So far, so good...
 
Like I said above, I would like to have one bushing on the throat area and then another ahead of the throat however far. I can do this now of course with the grizzly/Gordy rod, but I do worry a bit about running the tight fitting bushing back and forth across the lands as I dial in. I have seen slight tool marks from sliding tight fitting bushings. They don't seem to hurt anything, but I don't like them there. Lee

Do you buff the ends? Break the corners?

I do now after I saw what was happening. I make sure I have oil on my bushings as well. That's a good point or tip for someone new to using grizzly rods. Lee

How far do you insert your Grizzly Rods in the boor.
 
Does any one know how Dwight Scott and Kelbys dile in there barrels?
 
yes. you need multiple long stem indicators as well as .001 and .0001 indicators with plenty of mag bases. cant have too many.

I guess about 4 inches a times? I dial in at the throat and then again 2 to 3 inches in front of the throat. usually 2 inches in front. Barrels always shoot well. I started several years ago using this method and it has produced great results for me, so I never tried any other way. Lee

Thanks . I bought a Grizzly Rod and a set of bushings . It didnt come with any instructions at all. I called Dave and he told me to watch utube. Can you youse a o ring in the middle of the rod to keep it from canting? I saw a short clip where they yoused a .0001 indicator and measured close to the barrel and then moved out on the end of the rod ?
 
Can you post a link to the video you watched? Sounds to me like you watched a video of someone using a range rod, and not a grizzly rod? The o ring on a grizzly rod goes on the very end and separates the rod and the chuck that's resting in the tailstock quill. . You don't have to use the o ring, but I like to. The grizzly rod, sometimes called a gordy rod have to be moved in and out of the barrel by cranking the tail stock in and out. There will be a single bushing on the other end that goes into the barrel. When you move the tailstock in and out, you will be reading the deflection of the rod with a dial indicator set as close to the barrel as you can. Im not good at explaining stuff, but I hope this helps?? Post a link to that video. Lee
