Rechamber Savage 99?

Can a Savage model 99 in 300 Savage be rechambered to fire 308 Win? If so what all has to be done to the rifle?

I think it can be done dimensionally but as I remember there was a change in the 99, better steel etc, at one point to permit the higher pressure 308 to be used in the gun. If the gun was made prior to the change don't make the conversion. Actually the 300 savage is a good cartridge and was very popular here in NY. It's about 200 fps than the 308 with the 150 gr bullet.

I'll put it plainer than mete....

Why change? .300 Savage is a very nice round. As a matter of fact it is oneof my favorites. Great little brush gun. And if you really seek a Savage in 99 in have a great reason to buy another one. :D

I think, repeat THINK, that Savage lengthened the action a bit to take .308, .243, .358. A .300 Savage made after the .308s came out could probably be rechambered, but an earlier one, when the .300 was the biggest thing they made probably could not be. Nothing wrong with the .300 except you can't shoot foreign surplus ammo of doubtful qualilty in it.

The actual deal-breaker here may be the magazine. Most of the .300 Savage rifles came with the spindle-type rotary magazines. Those do NOT convert well between cartridge families.

But it can be done. I helped a widow sell off her husband's collection, to include several 99s. One was a custom .250-3000. The serial number indicated it would have started out as a .303 Savage or maybe .22 Imp. Done back when you could get parts, of course.

I rechambered a sporterized Arisaka from 300S to 308W with a few twists of the wrist on a reamer.

And I have a 308 Sav99 barrel lying around to see if the ammo feeds.

But I also have a 303 Sav99 that I have considered re barrelling, but the warnings are everywhere, the Savage 99 spindle magazines are nothing to fool with.

I would either learn to handload [where the 300 Sav is nearly idenical to the 308] or sell the rifle and buy another one. Sav99s are easy to sell.

My 1950 99R has a maximum OAL of 2.612.

FWIW, I can handload 300 Savage close enough to .308 that you and Bambi won't be able to tell the difference.

The 300 Savage is actually a pretty good round in stock form. It is to the 308 Winchester what the 308 is to the 30-06. Darn! Never thought I would be using that analogy stuff that I saw on all those Stanford learning standards tests and college admissions exams I took years ago! Anyway, for deer, the 300 Savage works just fine. I had a friend with a 99 chambered in 300. It was accurate, even with iron sights and he used it to hunt deer. I offered to buy it, but he was unwilling to let it go.

Stans, your post is to the question as South Park is to John Kerry.

Water capacity of case, max SAAMI pressure, SAAMI proof pressure range:
300Sav, 53 gr, 47 kpsi, 61.1 to 65.8 kpsi
308Win, 56 gr, 62 kspi, 80.6 to 86.8 kpsi
30-06, 68.2 gr, 60 kpsi, 78 to 84 kpsi

CDA 260 cartridge brass in the hardened state will start to yeild around 62 kpsi.

Problem is that the 308's are usaully quite a bit more expensive than the 300 Savage ones.
I have a M1A already and I would hate to have another chambering to have to buy for and I don't reload(yet).

Thanks for the replies, sounds like it will be more trouble than its worth. I guess, I'll just have to pounce on the next 308 Savage, I see.
