Ruger has a M77VT in .243 with a 1:9 twist rate. I think they use this same rate in the Ruger #1, also.

Most of the manufacturers web sites will list them for you, but I believe Remmy uses 1:10 or slower.

I have a 2008 Remington catalog and they list 9 1/8" on their .243's.

Yep...Remington uses 1 in 9 something...I thought it was 1 in 9.25"...Rockman says its 1 in 9.125"...not much difference though.

I have an early model Remington 700 VLS and I'm almost certain it is 1:9.5".

I have a brand new Savage Model 12FV with 1 in 9.25" twist. I've only fired 85gr Sierra SP and 75gr Hornady HP so far. I think these will be fine shooting bullets once I fine tune the loads and find the sweet spots.
I'll work toward the heavier and lighter ends of the bullet spectrum. I have some 100gr Hornady SP loaded but haven't shot them yet. I understand that the faster twist rates are to stabilize the longer (and heavier) bullets. Curious to see if the 1 in 9.25 twist will stabilize the Sierra 107gr HPBT MatchKing.

My 12FV in .243 shoots everything from 55-105 gr. handloads pretty decent, it really seems to favor the 70 and 85 gr. SMK's and SGK's though.

1-in-10" twist made the .243 Winchester Great
Modern 1-in-9 1/8" twist makes it better. Remington's .244 1-in-12" twist tossed away its deer hunting prowess, in exchange for great varmint light fare. Yea, I know, that's old news. 100 grain Speer Grand Slam .243 bullets are what makes the .243 Winchester so perfect for deer/hog hunting. 100 grain Nosler Partition bullets represent no wannabees also. New to the scene are 90 grain bonded Swift Scirocco IIs designed for 300 yard carnage. Apparently 10 grains of weight is not as important as .419 BC bullet design. I wonder what would transpire with a 100 grain bonded Scirocco III? cliffy

As far as I know, faster twist rates are necessary to stabilize heavier bullets, but in general don't cause problems with lighter bullets. So, if you want to be able to shoot both, choose a faster twist rate.
