9.3x74r - WHy did Ruger choose 1-20" twist rate???
|
Hello,
I thought the standard twist for the 74r was somewhere between 1-10 and 1-14, with the faster twist better for heavier bullets? Why would Ruger build their new No 1 Sporter with a 1-20 twist? Am I missing something?
I was really looking forward to getting one of these, but will the slow twist stabilize the standard 286gr slugs?Thanks

If that is true, it is another example of the strange goings-on at Ruger. They can't get much right anymore...will soon join Winchester at that rate.

We called Ruger today trying to find one of those 9.3 #1 rifles, guess what? They are not in production yet oh there may be a few around fron the shot show and stuff but they are testing the water befor doing a production run. This is typical of Ruger and drives people like me nuts. They have distributers addvertise a product that is not available and may never be.
Standard rate of twist for a 9.3 is 1 in 14 and this will not work very well with super long bullets like the Barnes X unless the velosity is low like around 2700 FPS. 1 in 12 workes much better where the 1n 20 twist came from I have no idea but I would be very suprised if it would stabilise light bullets forget the heavy ones.

I hope that 1-20" twist listed on their web site is just a mistake. I've been seriously thinking about buying one of these rifles (if they ever make them!) but if they will truly have a 1-20" twist then I'll pass on it.

Max loads in a 9.3X74R is in the 2300 fps range, so 2700 fps is not realistic, and not a worry! The 1-20 twist is not realistic, either, and would not stablize the 286 gr bullet, and the 320 gr would be worse. You might have to go as low 120 gr bullet to get it to spin properly. I can't believe Ruger would put a 1-20" barrel on that rifle. That is the twist they use in the 45-70, which just stablizes the 400 gr bullet, and works best with a 300gr .458 dia bullet.
Like Faucett above, I am thinking about buying one , but not if the twist is going to be 1-20" twist! I-12, or 14" would be proper for the 9.3X74R~

I expect that is just a typo with the twist being 1 in 10" or 12", not 1 in 20.
; A 14" twist would work just fine with heavier bullets in 9.3, as it does in the .375 and the smaller .358's with their longest bullets.
: I wouldn't worry about Ruger as they'll get the twist right. I'm sure.
: Barnes "X" bullet require faster than normal twists, and more guns aren't rifled fast enough for the heavier ones.
: Too, some guns just don't like the old-style Barnes "X", however I've had exceptional accuracy with the blue coated 120 XLC in my daughter's .260 Rem, and the 160gr. Triple Shock Barnes outshoots all Nosler and Speer bullets in my 7mm Mauser.

Hello Judson - Did Ruger confirm which configuration it might be offered in, #1S or #1H? Riley
