Re: Savage Model 1899
I can't precisely date that 1899 for you but you should realize that the serial number puts the date of mfgr earlier than 1910. It's 100 years old. Maybe more. Serial numbers below 90,000 have squared off cuts in the frame top where the back of the bolt locks. 90 degree corners create stress risers when a load is applied. This design was changed to a radiused corner. Look for insipient cracking there. If there aren't any cracks it should be fine. The Savage 303 round has about the same power as the Winchester 30-30 and so can take the same kind of game. It uses a 30 caliber bullet or 0.308inch diameter, same as a 308 or 30-06. Good luck finding factory loaded ammo. IT isn't the same round as the British 303.
There really isn't any reason to take the rifle apart Hank if that's what you're looking for a manual for. You have to clean the bore from the muzzle end.
There is a little trick that is good to know to decock the rifle when it is loaded or unloaded: With the action open and the lever down, place you finger on the trigger while raising the lever. Start to pull the trigger. You'll feel some interference as you raise the lever. Once the interference is cleared remove your finger from the trigger and close the action. The rifle is decocked.
Try googling steve's reloading pages. It's not me, another guy named steve. He's got a lot of manuals for downloading. You won't find one for that age rifle though but it may help.
