When the bolt closes on a chambered round it centers itself. The bolt cannot be pushed up since the cartridge base has it seized. One will just have to load the first round by hand to lock the bolt in position then all the ones fed from the magazine will follow.

Just a matter of how to shoot the gun. Having the issue while hand-cycling the action is aggravating, but knowing it will be reliable under fire is something else. Just never shoot loo it to empty, leave a live round in the action, reload and shoot on. I think it’s just the nature of the beast with most IJ’s or any commercial that did not have a barrel skirt. I did own a gen-1 Universal with no skirt, but it never missed a beat. The quality of the receiver obviously has something to do with it. Universal did use a forged steel receiver a lot closer to GI spec than IJ ever built.

  To be clear, I'm having no issues with the carbine other than the minor aggravation of the resistance when hand cycling the bolt when the hammer is down.. The rifle runs flawlessly and is as accurate as my other carbines. I do intend to replace the soft hammer, however.
  My particular IJ is a commemorative and I'm betting those were built for looking at more than shooting.

Yep, some carbines are for looking-at more than shooting. I have a stainless IJ only because they are the only ones that made one close to GI spec in stainless and it shoots very well.

From personal experience, let me suggest that you not install a GI hammer behind an IJ bolt. The GI hammer will surely last an eternity (practically), but it will aggravate the destruction of a cast bolt. The commercial hammers tend to be sacrificial and lesson the bolt damage by absorbing some of the punishment. It would be better to replace the bolt and the hammer as a set. However, IJ carbines were mass head spaced to IJ bolts, which tend to run a bit longer. You might get into head space trouble changing to a GI bolt. 

I can offer another suggestion to minimize bolt and hammer damage. Hammer springs are relatively cheap. You can shorten a 26-1/2 coil spring down to 1.97” and still get solid primer strikes. You can collapse coils on each end. A slightly weaker hammer spring will both reduce the pounding on the bolt and even smooth-out the action a bit. There is a limit and you can go too far, but the spring can be adjusted.

So I have an update. I purchased a used IJ bolt in good shape it said. Arrived today. Greased it up a bit, wiped it off, installed it into the IJ carbine and re-assembled the rifle.
OH YEA! man OH YEA!  There is still a resistance when it tries to rotate the bolt, however it doesn't move like the old one. It's a lot more like the Inland in operation. Much tighter. I'm a lot happier with this bolt. I can't wait to take it to the range and run a bandoleer of Korean ammo though it.

Does the Extractor sit 'Lower' on this bolt vs the other one?
I hope it's a good range day for you.
