The bullet that is further into the bore is the 174 grain Remington UMC FMJ
The bullet that has more showing is a Winchester 180 grain

So my question is judging by this, is it considered a decent crown? Looking down the barrel in the light the rifling is still nice and sharp with light pitting which is to be expected in most of these rifles.

Yes, I would say it looks fine.

There was a guy who did tests on a Lee Enfield barrel crowning, he basically started at the end and cut up the front, on odd angles too etc., and it was evident that the barrel crowning, or lack of, did not really effect how the rifle shot. At least not for the average paper shooter.

How does it shoot?
 
It actually shoots prettt decent I have only shot it at 25 and 50 yards and have been able to get decent groupings for
My skill level was able to get a fist size grouping at 50 with the rifle rested sometimes with the odd flyer, some people may laugh at that but that is my skill level and thought that was decent for a old rifle.

I was wondering there is a big difference with this test between the 2 bullets I'm guessing you
Would judge it more by the 174 grain?
 
But still considered a decent crown with the 174 grain? Scared a 150 grain would get swallowed haha even though many people may not shoot 150s out of the rifle
 
The bullet has a maximum diameter of, say, .312", regardless of its weight. At some point the ogive is going to transition to full diameter.
Using a bullet to gauge bore diameter at the muzzle is a quick and dirty way to see if the bore is oversized. I've seen muzzles so damaged that they would swallow a cartridge all the way to the shoulder.
If you want to inspect the crown, use a magnifier and see if the edges of the lands and grooves are reasonably sharp and well defined.
