I just bought a winchester 308 model 100 rifle,

There are 3 varients of the 100.

Model W8015 - .243
Model W8092 - .284
Model W7973 - .308

no
there is a small lip that pulls the shell out of the breach as the bolt moves back
take it in to a firearm repair shop and have it properly fixed

Savage had a long history or caliber changes with that rifle. Anything from for .303 Savage, .30-30 Winchester, .300 Savage, .25-35 Winchester, .250 Savage (also called the .250-3000 Savage, .22 Hi Power, .22-250 Remington, .243 Winchester, .308 Winchester, .358 Winchester, 7mm-08 Remington, .284 Winchester, .38-55 Winchester, .32-40 Ballard, .375 Winchester

The most common stamp showing c3 was for 22

this question is a bit silly since eventually you will need to resight your weapon for the new ammo anyway. So spend the time and the ammo costs to go to the range and do it right, right from the get go.

this way you won't need to recalculate drop rate and use kentucky windage for every shot at differing ranges.

Recommend from USMC sniper/rifle expert.

If it has an empty case in it you could slide your cleaning rod in from the muzzle and tap on it to see if this would help move the bolt back any. DON"T do this if it has a live shell in it ! hope this helps

The following is Wisner's rendition & info on the subject.
The difference in the old firing pin and the new one is as follows. The old replaced
style, was totally lathe tuned (round). While the new recall style is similar in lathe
turning on the front and back, but in the front midsection it has two flats milled, one
on each side. This makes the center section stronger. Also replaced is the bolt sleeve
lock pin (firing pin guide) which was made to accommodate this different shaped firing
pin
Part number for the new parts are, firing pin =1391ND, bolt sleeve locking pin =1491ND
The word was at the time this recall was in process was that if the firing pin would
break at the mid section and still remain in the gun as two pieces, the possibility of a
premature discharge before the bolt was locked was possible. This apparently was caused
by the firing pin tip (now not having a retracting spring) to be stuck forward, and
thereby slam-firing upon chambering.
The responsibility for the recall apparently was on Olin, as they were the parent company
at time of manufacture. Olin set up regional recall centers at three established US
gunshops. There was a manufacturing delay in the replacement firing pins, and a backlog
occurred, also some collectors did not like the idea of shipping their guns long
distances. Olin then also authorized other gunshops to make the required alterations.
Upon completion of the recall, the shops were to test fire the firearm and to stamp an
assigned letter on the inside top of the receiver as seen thru the magazine well with the
bolt retracted. The letter “B” represented Bolsa Gunsmithing, “L” was Lefever, and “N”
was for Nu-line Guns. The letter “X” apparently was for all the other independent shops.
However this identification information did not get communicated to some of the smaller
shops at the start of the project. The only way to tell if the gun as been modified, if
the ”letter” is not present, is to take the barrel & action out of the stock, remove the
trigger guard assembly and the try to rotate the firing pin by twisting it. If it does
NOT rotate, then the firing pin recall HAS been performed.
