"Case Lenght" shouldn't have any bearing on the action cycleing/feeding.Unless they are too long.
The "OAL Cartridge Lenght" would and the case lenght dosen't matter on that one,nor the bullet lenght.It is the seating depth of bullet that does matter.A long bullet can be seated deeper into a "Spec Lenght" Case to get the correct OAL.
Why these cases are under spec lenght I don't know but the bullet lenght ain't got a thing to with it.The 30/30 and 35rem are also longer but the case lenght is still in specs on those I have.

I haven't looked at that particular cartridge, but I suspect that the ogive on the new bullet is very long to get somewhat better downrange ballistics and that results in a long bullet nose which has to be seated deeper. The portion of the bullet where the cannalure is probably farther back and with this being a tubular magazine gun it must be crimped for safety. Their only resort to get a streamlined bullet and a crimp in the cannalure was to shorten the case. Bullet length didn't cause it, but bullet nose length did. The smaller calibers wouldn't have had so pronounced a nose length increase.
I can see where this could cause some problems to the unwary if one suddenly took cases and loaded them with old loads seated to the cannalure without measuring the cases. Suddenly you have a smaller case capacity and boom. Of course everyone should always measure and trim cases, but people do things.

Well put Whelen Man, like I said the long nose I think was the kicker to shorten the case

I measured my brass for my 450 Marlin and the factory loaded ammo's brass was about .050 shorter than unprimed brass from Hornady. The brass had the same headstamp.
.7230 Factory loaded brass HLE
.7760 Unprimed brass

Tiny what you say is interesting and I think we could have a great time talking. I wonder if the length of the rubber nose is the same length as the decrease in case length? What I've run into with the 358 Winchester and the long nosed 225 ballistic tips is that when you seat the bullet to the specified maximum COL you wind up without the full diameter of the bullet at the end of the case and there is a space between the bullet and the case. Luckily mine is a long throat and long magazine and I can adjust by seating longer. It's probably some combination of these factors. It's an interesting route by the factory though.
and same here on the good time talking.
