Given the limited information in your question I can only give a general reply. The caliber is the diameter of the rifle groove to groove in thousands of inches. So the difference would be .450" - .308" which equals .142". There are a lot of specified rounds of ammunition that use .308 and .450 bullets. In general the larger caliber bullet would also be more powerful.

What is the difference between 308 and 303 if they both use a 30 caliber bullet or do they?
The actual diameter of the bullets are both 30 cal. The brass casings are different for each rifle. Therefore, to distinguish between the two, (since they are both 30 cal, you can't call them both 30 caliber, or else you'd get the bullets mixed up for each rifle) they label the 303 by the diameter between the "lands" (.303 inch from the rifling surfaces in the barrel) the 308 is measured from the grooves. (.308 inch from the depth of the grooves instead of the surface of the lands.) They both fire a 30 caliber bullet, but they are designated using different measurements in order to keep from getting the different size casting mixed up between rifles.
What is the value of an Enfield 308 bolt action sniper rifle?
No such rifle. The Lee Enfield was made in caliber .303 British, not .308. The closest thing would be the Ishapore 2A or 2A1 rifle, made in caliber 7.62 NATO. While similar the .308 Winchester, it is not the same, and .308 should not be fired in a 7.62 NATO rifle. The Lee Enfield "sniper" rifle in .303, if original and complete (and not an aftermarket conversion) may sell for around $1500, depending on condition and accesories. There are many fakes on the market- be sure of what you are buying.
