Roper,
Ok, are these custom rifles by your definition?
Springfield 1903 High Number Action made in 1918, Remington 1903/A3 barrel made in January, 1944 shortened to 22 inches with a deep recessed crown, Parker modified adjustable trigger at 2 1/2 pound pull that breaks like glass, Bell and Carson Stock glas bedded, Redfield base, parkerized finish all per the customers specifications.
1938 Oberendorf Mauser Action, E. R. Shaw 19" inch barrel in .308 Winchester, Hogue Stock glas bedded, Huber trigger, 2 lb pull, Leupold one piece base, parkerized finish as ordered by the customer.
Remington 1914 Enfield Action, E. R. Shaw .338 Winchester Magnum barrel, Redfield one piece scope base, straightened bolt handle, shortened bolt stop, ears removed, Dayton-Traister trigger 2 1/2 pound pull, Cock on opening, MPI Synthetic stock glas bedded, parkerized finish.
These are by my definition one of a kind custom rifles.
And I consider these to be a custom rifles:
1903 Springfield made in 1932, barrel shortened to 19 inches, Walnut Mannlicher stock, full length glas bedded, Redfield one piece base, Low scope bolt handle, Timney Trigger.
Iranian Mauser Action, barrel shortened to 18 inches, Walnut Mannlicher stock, full length glas bedded, Leupold one piece base, butter knife bolt handle, Dayton-Traister trigger.
New after market barrels and custom throats are not needed to make custom rifles is the point.
I have built what I consider custom rifles using Savage 110 and Reminton 700 factory new barreled actions based on the customer order using various stock types all glas bedded that shot in the 1/2 range for 3 shots at 100 yards when completed.
