Keep in mind those twists are simply what was/is used in those firearms. The choice of what twist to use by a manufacturer is most often based on criteria other than what is the best twist for each cartridge to use, especially with cast bullets.

The latest Win lever guns were 26 twist. The so called Legacy guns were anyway. The twist is absolutely perfect for any and all ammo you'd want to shoot. ... felix

I second what Larry said, but this is a fantastic compilation none the less!
I'm going to print it, and sticky it.
Bravo!

Great list, thanks for posting.

Does anyone have definitive info on the Henry Big Boy .44 Magnum and .45 Colt rifles/carbines?

They're both in the OP - 1:38"



.

I must be blind, I looked hard because discovering that was my principle interest in scanning the list. Thank you again.

Don't sweat it Ian, that's one heck of a list!

.

Don't worry about your reading/comprehension skills - I regularly update the OP, when I acquire new/additional info. :popcorn:

40-65 is 1:16
400 Whelen is 1:14" or 1:16"
45-110 can be from 1:18" to 1:22"

Thanks for your contribution, Frank - but:

FWIW, The reference is meant to be a useful knowledge/comparison of which particular commercial rifles use which particular twist rate, for whatever commercial cartridge.

Your information about the .40-65 & .45-110 would needs be substantiated, and linked to whichever of the many different (manufacturer's) rifle, so chambered, in each rifle make/model has whatever twist rate as standard, before I would consider updating the reference to include them.

The .400 Whelan is a wildcat, and any such bbl would ergo be custom/non-standard - why the listing only contains factory/production cartridges linked to Standard-production, commercially-available rifles, and no wildcats.


.

This might not be of any importance but: The current SAKO and TIKKA rifles in .308 and .30-06 are 1 in 11".

My Browning BLR 358 Winchester is also 1 in 10 like the MS.

Petro,

will you include some smaller cartridges?
The .25ACP (similar in size to .25 Stevens Short) has twist of from 1:14 to !:9.8 currently.
It is Not limited to short barrel concealable Pistols any more.
it 'works' in Stevens Rifles chambered for .25 Stevens and converted to CF.
and I have A 10-5/8" long barreled Ruger Single Eight in .25ACP, makes an interesting revolver. A friend can hit a 12" steel 'gong' at 1oo yards with my revolver.
Sadly my "hold" is not as good yet. i only get 'occasional' hits at 100 yards.

Best Regards,
Chev. William

Handi Rifle 30-30 barrels have been offered in both 1:10, and 1:12 twist rates. I know of a couple NEF Handi's from the early 90's that have 1:12 twists.

45-70 (Uberti High Wall) 1:20

Many rifles chambered in 300BLK are 1-8" twist to handle heavy 200+gr bullets.
I've discovered my 30 Herrett AR15 likes 1-8" twist also ;)

.300 Blackout(ANDERSON) 1-7"
.300 Blackout(ARSTONER) 1-8"
22-250 Tikka T3 1-14", limited edition T3X 1-8"

Pietro - re Post #1, my 99 Savage .30-30 is definitely 1:12, measured again this evening (table in Post #1 shows 1:10). This is a 24" factory replacement square thread barrel from 1980.

.

The specs I posted are original twist rates, some of which may change over the years.

Also, although some rifles have been re-worked to accept small cartridges originally meant for handguns, my twist rate listing reflects the choice of original rifle maker's - not custom/re-works or wildcats.

.

Thank you Petro!!

I cannot in manage how much work and time you spent gathering this information.

This is invaluable!!

Thank you again!

Cool...........
