Hello

Firstly, thanks for all your terrific posts. Just like all of you I love the 99 and its great to read them. I have a 250 built in 47 and I need to know the twist. I've read that all savages built after WW I were 1 in 10 but I've also read posts from oners of 1920's built guns that say theirs' are 1 in 12. Could some shed some light on this please.

Thank You

Welcome to the forum,

Check it yourself.

Push a tight fitting patch down the bore. Make a mark with a Sharpie pen on the cleaning rod and measure how far it goes down the bore when making one complete turn. That's your twist!

If it's an original factory barrel it's 1 in 14.

Post million serial number (1960) are 1 in 10

Don't believe the crap posted on those novice web sites. Good you found the right place to ask!

As stated, the .250 is 1-14 +/- due to equip wear until the million mark changeover to 1-10 in 1960. Also, as stated, you can measure it yourself if diligent to the process.

Welcome to the 'Fire!

Thanks for your replies. My main concern is trying heavier bullets. I love the gun. It shoots winchester (found an old box) and remington 100 grain sub inch which is "supposedly" not normal for a 1 - 14. Going to try Hornady 117 and and Nosler BT 115. In my research I discovered that its not the total length of the bullet that matters; its the length of the actual bearing surface. I measured the bearing surface on the Hornady 100 and 117; they are the same length give or take 100th of an inch. If this holds true at the range the Hornady shoulda do ok and the Nosler won't. Will let you guys know how it turns out.

Have fun trying, but it's the total length and not just the bearing surface. The commercial 100gr bullets usually work because they use shorter bullets for the weight.

Welcome to the campfire!

I always like reading people's test reports, and await the findings with those heavy .25s, but I fear Calhoun is right, for I remember him doing a fair bit of testing in that regard. Length matters, not length of bearing surface.

Any data regarding heavy bullet performance in the .250-3000 is almost meaningless without knowing the exact rate-of-twist in that particular gun as well as velocity (chrono'ed not guessed).
As stated earlier, there was a fair bit of variation in actual twist rates with earlier guns. You might get lucky and have a barrel that will spin those 117s enough to stabilize and yield good accuracy, and if so, get thee to the nearest Lottery agent for your luck is running hot. Personally I would save those heavies for something/someone else as it would be a shame to waste them on a wild goose chase, but that's me.

The 100 Grainers Both in winchester and Remington Do well For Me.
I tried the 117 Grain Round Nose From Hornady and They Shot Well Out Of My E.G.'s and R's Made in the 50's, But not So from 40's down. And My Saddle Gun in 250 Loves the 117 Grainers,
Steve

Welcome, I have a 250 R made in 1950. It loves the 100's. After sighting in a new scope with Remington 100's we tried some Nosler 117's. The first shot drilled the bull, thought I hit the jackpot. The second went through the paper sideways and the next two were several inches out to the right and left. Gave up, Joe.

Measure your twist it varies some from rifle to rifle. My 40,s 250 Savage measures one in 13 and change and shoots some longer 100 gr bullets well but it has 24" barrel. My other 250 Savage measures over 1 in 14 twist. Only way to know is measure twist and shoot it.

Just to wad the panties, don't forget the Chicopee barrel in the safe with the 1-10 twist...
