Thread: 22 Terminator 1-7 Twist

Just got the new 22 Terminator going with a 1-7 twist TF UM barrel.



It has a PSE stock I got a while ago.



I have been wanting to build a 7 twist for a wee while now to shoot the 90 Bergers with their .551 BC



I was quite surprised with the velocity shown in initial testing & I think there is more in it with the 90 Bergers.

It is only 150-175 fps behind my normal load in the 22-243 & a heap less powder.

I can push the 90s beyond 3200 fps in the 22-243, but they have a nasty habit of self destructing mid-flight, the more heat the worse it gets

So 3100fps is a happy medium with the 90s in a 7 twist
