Gain twist.

[bruce moulds]

kurt,
I have a 400/408 one which is stainless and goes from 26/1 to 13 /1.
I am most happy with it.
I think bartlein can also do gaintwist to order.
if I could not get another, straight twist is good also.
it sure strips paper well.
sometimes you just have to try things. you will love doing snowbank tests with it.
one thing I have found that aids accuracy is that either the front of the bullet or the rear of the bullet takes control of the bullet.
you can see this because the rifling marks in the bullet are wider at one end or the other.
best accuracy seems to be when this happens at one end for all shots, that end being preferably the rear.
if bore riding noses on greasers bump up into the rifling, they seem to take control.
these problems do not seem to happen with bore dia pp bullets.
ron smith is quite a character.
benchrest guys are using less severe gains than 2:1.
keep safe,
bruce.
