No
.308. which is 7.62
308...A 7.62mm = .300
Between .303 and .308 lbs per cubic inch, depending.
Enfields are in 303 Cal not 308......depending on the model anywhere between 300 an 900 dollars.
Yes it is.
308 is more than 8 times the size of 37.
No
Yes. Significantly.
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.
Both fire the same diameter projectile.
