I had a P-17, .30/06 Remington Model 30 that actually had a P-14 action. It is easily distinguished by the magazine cuttout. If the rails are straight, it was originally a .30/06 P-17 action. If there is an enlarged cuttout in the rails, kind of rectangualar in shape, just head of the bolt face(retracted) the action was originally a P-14, .303 action.
: It matters not, except that the real P-17 rails would have to be opened up to feed the magnum case, and the P-14 action will likely feed just fine, as-is. Such was the case of the one I had. Perfect feeding after opening up the bolt face for the mag. case.
; As a .30/06, the barrel was slow - 200fps slower than anything in the books for the identical loads at max pressure, mind you. Only the velocity was low. The barrel was indeed a .308 groove diamter, newly put on by Remington, way back when - late 1940's to 1950's probably.
; I re-chambered it to .300 Win Mag in a hope it would deliver 2,900fps with 180gr. bullets. Re-chambering it only, turned that slow barrel into a fast barrel, delivering 150fps to 200fps higher velocities than the books as well as delivering sub MOA accuracy with select loads. Before, as a .30/06, is wouldn't shoot inside 2 1/2" with anything lighter than 180gr. With 180's and 220's it was a slow, .303 ballistics, 1-1/2"er. As a .300 Winhester magnum, the roles reversed and 165gr. bullets reined supreme. You just never know. This wasn't a problem, as it put 165gr. Failsafes into 1" groups at 3,265fps and with 165gr. Nosler Partitions at 3,365fps made even smaller groups, same POI, same load of H4831SC.
: This indeed was a good move, re-chambring that old, slow .30/06, wasn't it.
: If the gun is in resonable shape, $99.00 is dirt cheap. I'd buy that gun just for the action.
