- 1) the Mag case has thicker walls and head, and thus
- less case capacity.... [-]
- 2) the Mag cylinder is ~.2 longer, so even if the OAL
- is the same, the bullet from the mag will have that
- much more to travel before it hits the barrel swaging
- cone and the pressurs start to climb. It could be
- that the pressures drop so low that your risk getting
- a bullet stuck in the barrel throat. Then again, the
- bullet slowing to a stop in the barrel throat, and then
- producing a pressure jump is a possiblity. If this is
- true, I'd expect to see warnings about shooting
- specials in mag chambers.
-
- 3) [my most likely canidate] Simple paranoia on the
- authors part. There are these persistant stories about
- powder detonation, and I think they are covering their
- ass.
-
- BTW I seem to remember that Ed Harris _may_ have mentioned
- that detonation has finally been seen in the lab. I'll as
- him and post on the response...
