Will BAT barrel fit Panda, with spacer?

I was looking at something about the Atlas, something about a BAT ring, and then I got to looking at the tenon specs, or should I say looking for. I couldn't find all the details needed to make a full comparison. So, if you used a spacer, would a BAT barrel fit on a Panda?
 
Thanks fellows. That is the reason that I asked here. I knew some of you that are doing your own barrels would have the info.
 
There are several BAT's out there with the Panda tenon and cone angle so you may run across one every now and then. I heard that BAT won't make them that way now but that wasn't from them.

Just thinking on paper here but a barrel cut with a 25 deg cone will still work with a bolt nose with a 30 deg cone as long as the gap space is not exceeding specs, namely that the gap space does not get past the brass base of cartridge.
If the barrel was cut with a 30 deg cone and the bolt was a 25 degree then the barrel and bolt would interfere in the extractor or outer area and thus almost guarantee that the gap space would be excessive with out modification.
 
The degree of the cone on isn't a problem with trying to put the normal Bat barrel onto a Panda. It's the shorter length of the tenon by about 1/16". The shorter tenon length would give about .062" of gap space between the barrel and end of the bolt, not to mention that headspace would be too long. The Panda tenon is close to 1 1/8" in length while the Bat is close to 1 1/16" in length. If you tried to put a Panda barrel on a Bat with a spacer then you'd have the cone getting looser as it goes in towards the center of the bore, resulting in excessive gap between the end of the bolt nose and the start of the chamber. Another dangerous situation. I have a Bat B action that has the same headspace, thread length and cone angle as a Panda. There are some of them out there so you can't take anything for granted when it comes to fitting a barrel.

I had the same thought. Looking back, I had the question backwards. It should have been can a panda barrel fit a BAT. It looks to me like if the pitch diameters are pretty close, and the Panda barrel is chambered with a 25 degree cone, that with a spacer it could fit a BAT.
