During WWI we actually produced more 1917 Enfields than 1903 Sprinfields.
The 1917 Enfield was simply a British Pattern 14 Enfield redesigned to handle the 30-06 cartridge. The pattern 14 was actually a Mauser action which the British had intended to replace the old SMLE with. It was also going to be a .280 caliber.
When WWI came along they abandoned the .280 since having two different cartridges would have been a logistical problem. They contracted with American manufacturers to make pattern 14 Enfields in .303. I am not sure how many were actually made but I once had a pattern 14 in .303.
I had it finished in matt blue and the bolt redone to cock on open, and the scope mounts redone.
The stock was rough and sanding out the diamonds would remove too much material, so I cleaned it up and coated it in truck bed liner. I installed a Timney trigger and a Burris ballistic drop scope.
My hot 200 gr Partition loads will put 3 right around a quarter at 100 yards. Pretty good for that old .06 barrel!
