Twist Rates

[DeerhoundLurcherMan 997]

Just sent off for my first centre fire variation (.223).

 

Got thinking about twist rates, from what I have read the faster the twist, the gun will stabilise heavier bullets...?

 

So why would anyone choose a 1.12 over a 1.8 is there any cons to a faster twist?

 

Cheers.

1:12 are more readily available. I had the same thoughts when I bought my Tikka .223 until I found I could have a 1:12 the same day but a long wait for a 1:8.

 

A 1:12 will stabilise up to 55gr bullets which is perfect for hunting. 1:8 is for heavier stuff and more sought after by target shooters.

 

Again, horses for courses.

Just get the standard twist pal, if you want to fire 75 grain bullets, get a .243.

as said the 1/12 will handle up to 55gr but the 1/8 will handle everything from 40gr to 80gr. the reason 1/12 is seen as the standard twist for the .223 is it was mainly sold as a hunting/ varmenting round and the heavier bullets weren't needed. now a lot of people want one gun to do both hunting and target shooting and this is where the 1/8 twist comes in because it will do both. my rifle is 1/12 twist but I bought second hand at a good price, if I was buying a new gun I would go with a 1/8 twist.

1-12" is fine for hunting, i used 40grn bullets in my .223 and it was a very good fox combination.
