No You could build a rifle in .306" or any other caliber but you are likely referring to 30.06. A 30.06 rifle is referred to as "30 Caliber" but to be accurate it is nominally .308"
compared to most other rifles, yes. i have been shooting for 10 years, i am used to it.

NO. There is a 30-06 rifle, but it is still a .30 cal, just like a 308 or 30-30 If there were, it would not be a rifle, it would be more like a cannon.. The caliber of a rifle, is based on size of the hole in the barrel, hence .50 cal is = half a inch. and a .30 is just slightly smaller than 1/3 of an inch. ****************** While there are .307 caliber rifles, have not seen a .306 or 306- as the previous responder noted- there IS a 30-06 (Usually pronounced thirty ought six). Yes there is. It is a 7.5X55 Swiss rifle. The surplus ammunition bullet diameter is .306.
100-450 usd
Depends a LOT on which rifle, and where. The rifle used by the Union Army at the start of the US Civil War originally cost $20 each. In 1860, that was a LOT of money- about 3 months wages for a worker.
About $100 for a good used one.
If you are looking to purchase a used rifle in good condition,the cost will be between 475-600 dollars.
This question is unanswerable. After extensive searches, no information about how a 306 turbo can be used in cars where found. The only results found are for a bunch of Peugeot 306 turbo cars.
probbably a hell of alot of money since 306 wasnt made past 51 plate .
Depended on the rifle. $5-$500
