R.Marshall,
Not knowing where you live, I don't know if there are any gunsmiths in your area. I think if you can find one with headspace gages, he can determine the correct chambering of your rifle. If it is 6.5x57, as I think, it will close on a 6.5x57 go gage, but a 6.5x55 should not. Headspace gages for 6.5x55 are more common than 6.5x57( in the US); if the bolt will close on a 6.5x55 no go gage it is likely 6.5x57, but if it won't it is likely 6.5x55. I hope this doesn't confuse matters more.

I'm getting a lite primer strike with this transitional action. I think I have it cleaned good and bought some different spring to try from 22Lbs to 30Lbs. It did not fire with the 22lb spring. So I'm a little lost on what to do next.

R.Marshall,
If you already changed springs, you might check firing pin protrusion. Firing pins are sometimes damaged and replaced or sometimes "cleaned up"( meaning re-contoured, not actual cleaning), either could result in reduced protrusion. It is hard to ID a problem with out the rifle "in hand", some transitional actions were made with the new style firing pin that required the bolt to be fully closed or it wouldn't fire; it would have the two protrusions where the "Pin" part comes from the main body. The old firing pin wouldn't have this, it would be round here like a 93/94/95/96 action. If an old style firing pin was replaced with a new style one, the protrusions or maybe partially removed ones might interfere. This is also a traditional sign of excess headspace, but I did note you were using 6.5x57 ammo, and the chamber cast didn't indicate re-chambering to 256 Newton( a somewhat popular modification). If you have another Mod 98 Mauser, it might be instructive to test the rifle with another bolt and check the firing pin strike. If it is still too light, you might stack .004-.006" of shim material between the cartridge head and bolt face of the original bolt, and see if it closes w/o force.

I would call that quite a bit deformed. Better measure that fired brass and compare it to the chamber specs. Looks like a polished or possible re-cut chamber to me.

6.5-08? Neck down a 308 and try it.

Well, how about https://en.wikipedia.org/wiki/.260_Remington
No, you said a 6.5x55 chambers. You may have to work over a 308 case until you can get it to chamber and then fire form it out with a few grains of pistol powder and cream of wheat filler and have custom dies made.
