Transfer bar hangs on bottom of the firing pin

[LONGTOM]

Could use a little help with this one.
I just put a 22-250 barrel on one of my extra frames.
It locks up tight but doesn't quite have the free play in the barrel release that it should have.
I am sure it just needs a little stoning on the shelf.
No big deal.
I haven't done it yet as I am not sure I am going to keep it on this frame.
My real problem is when you pull the hammer back the transfer bar hangs on the bottom of the firing pin.
It doesn't do it all the time and if you pull the hammer back quickly it will work correctly 90% of the time.
If you pull it back slowly it will hang at least 99% of the time.
As the bar slides up it hits the bottom of the firring pin which prevents the hammer from going back.
If you raise the muzzle up in the air the bar falls back and clears the firring pin every time.
I have never run into this on a Handi before.
The gun shoots very well using Winchester white box 45gr HPs but I did have a lot of FTFs.
8 out of a box of 40.
Somewhat light on the primer strikes but not overly so.
I didn't have any other ammo with me to try so at this moment I can't say 100% if it is a firring pin problem or the ammo.

While typing this I stopped and did somemore checking on this gun.
It is a new CBA frame.
The barrel latch is locking even across the shelf but only about 3/32" so I am sure it would need a little work.
Pulled out a couple of my extra frames, an HX and a NW.
After removing the barrel and compairing the three I could see some differences between the two older frames and the new CBA.
The top front of the transfer bar that slides up over the firing pin has a slight bevel or roundness to them on the older models.
The bar on the CBA frame has none at all.
I am sure this is what is causing the bar to hang against the bottom of the firing pin.
Should be an easy fix once I take it apart.
Will have to study up on the disassembling part first!!!
I tried the barrel on the other two frames.
A little loose on the HX but a really good fit on the NW.
I will try the ammo in this setup and see if I still have a FTF issue.
If not, then it is the CBA frame.
If it still happens then it could be the ammo.
I will give an update on the FTF issue.

Now, after you have done a lot of reading, and it seems that I have fixed my problem as far as this barrel lockup goes by switching frames, am I on the right track about the transfer bar problem in the CBA frame?

If it was with a factory fitted barrel I'd call H&R and make arrangement to have it sent back and fixed, but it sounds like it's an extra frame. The bottom of the firing pin should be beveled so the t-bar rides right up the back of the pin, a little adjustment of the lower edge of the pin would be all it takes to cure the problem. Both of my new Ilion frames have t-bars with no bevel on the front edge.

You are correct in that it is an older barrel on a newer Ilion frame.
Or it was on the newer frame! 

Got it.
Same idea just a different part.
Still need to study up on the disassembling part.
Thanks Tim.

i had the same problem on a shotgun frame. Did a little stoning on the bottom of the firing pin, beveled the top,forward edge of the transfer bar itself, and stretched the lifter spring a little before reassembly...it works now

The whole front edge of the T-bar doesnt have to be beveled, just where it is hanging at the F-pin. You could cock it, stuff in some rag, and just break the edge of the T-bar at the F-pin contact spot and it might fix it.  (remember to pull the rag carefully and wipe down inside with an oily Q-tip which will stick any debris)

Follow up on the FTF issue.
Looks like the FTF problem is related to the transfer bar problem on the CBA frame.
I took the barrel that is now mounted on the older NW frame and the ammo that failed to fire yesterday (even after two trys) and ran them through the gun today.
Every one fired on the first try with much better firing pin contact.
Looks like that problem is solved.
Now to find an ammo that the gun likes until I can do some load work for it.

Since I bought the CBA frame new I may have the gun shop where I bought it send it back for me to be repaired.

That sounds like the way to go, if they will send it for you, and make sure you get that 'heavy' trigger fixed too  .

[quickdtoo]

Seems to me Lonewolf5348 sent a frame only in for a trigger job, so they should fix the t-bar issue, but if there are FTFs, they'd want the factory fitted barrel too.

With the FTF you have to hold the trigger back and safely lower the piece, keeping the muzzle downrange. See if you can get a look in at the hammer/T-bar contact zone........my guess is that the T-bar hung up and didnt make it fully into position when the hammer fell. Its worth a look anyway to try to sort it out.

I am inclined to agree with you on that.
Kind of hard to see with the scope on.
I beleave that if it goes back and they fix the T-BAR problem that in its self will correct the FTFs.
I no longer have the factory barrel.
It was a 24" 204 which I traded for this 22-250 barrel IIRC.
