Will gain twist barrels work well for rimfires?

I think they were around a few years ago. Don't know of anyone who has tried one. The single shot Sheutzen guys seem to like them.

We've got a couple out there now. The first guy got one on a BR50 gun I think for an unlimited class gun.
He took it to his first match back in Sept. I think. Shot well with it and won his class.
Yes the Schutzen guys seem to like it.
The gain twist is working for centerfire guys on the short range bench guns!
That's all I can give you for now.

Frank,
Couple of questions if I may? What twist are you doing for .22 rimfires. What groove and bores sizes are available?

Kent, We can do them in anything you want as far as twist goes for the most part. Remember tooling still plays a part.
Standard is 5 groove barrels. Bores are standard .217. We can cut the grooves to the standard .222 or make them smaller or larger. If larger there would be an extra cost of about $25. Gain twist type barrels are $75 more also.
I don't see a tight bore (.215 etc...) shooting any better than a standard bore. The more uniform the bore size over the whole length of the barrel, the straighter the blank the more forgiving the blank is going to be.
Last month in Australia for a state championships a two people shot our barrels and took 1st and 3rd place and set a new Australian record either for group or score. I don't remember which. I believe they we're a husband and wife. They're barrels we're standard .217 x .222 and straight 16 twist and the customer paid for special tooling as he wanted his barrels to be 6 groove with a 50/50 land to groove ratio.

Frank,
Do you make 4 groove barrels in RF configuration as well? I like 4 grooves. They seem to dial in well on the lathe. I'll give you a call after the first of the year. if you don't mind and discuss. I have yet to try a cut rifled barrel, but the cut Border barrels shoot very well.
