I have also read you can really dial this cal in. I dont know if the 1 in 14 twist will shoot these heaver bullets, or can you drop the amount of power to stablize the bullet? Bill Maylor.
At 22-250 velocities the 1 in 14 twist will shoot the 55 gr very good. the 60 gr may be OK but
it depends on your rifle.
The 1 in 14 twist was designed for 55gr bullets and down. mine loves the 52 gr hp.
Now that there are much heaver bullets you may have to go to a 1 in 12 or even a 1 in 10twist.
The 223s are using 1in7 or 1in8 twist but they are much slower than the 22-250 or the Swift.
I have a 223 WSSM I'm testing and with a 1 in 15 twist it seems to be capable of shooting
the 64 gr with good accuracy (the velocity so far is 3922ft/sec and an SD of 0006.
So velocity has a lot to do with whether it will work or not.
Just an opinion
