RE: Need some help with Twist Rate!!!!
The RR will be used for groundhog hunting out to 300 yards. I use a heavier caliber past that distance. It will also be a fixed position rifle. I will also use it for off hand fun shooting. I am not a competitor. I also think that the 52 grain bullet would be optimal. I was thinking about the 20 inch barrel. Thanks for your help. Tom.

The 1:9 twist is perhaps the most versatile of all the .223 twists. It can shoot bullets up to the 75 gr. Hornady A-Max; and still group pretty well with bullets in the 50 and 55 gr. weight range. Obviously if you were going to shoot only 55 gr. and lighter bullets, you would choose a 12" or even 14" twist. But I have been amazed at how well 9" guns will often shoot bullets like the 50 gr. V-Max.

The only down side to faster twist rates is it seems to magnify bullet and load imperfections, so you'll need to work a little longerfinding a good factory loading or working on a reload.I would opt for the 12FV though in 22-250, it's closer to optimum with a 1 in 12 twist. If your fixed on the 223 round take a look at the newRemington 700 SPS Varmint which does have a 1 in 12 twist and should be less finicky, price should be close.

The RRA Varminter only comes in 1 in 8, I had this very gun with the 16 inch barreland it shot .5 groupswith Lake City55 GrainFMJ, so I think the lighter bullets are not a problem in the long run,but faster twist rate does magnify bullet imperfection's though, so use a quality ammo like Black Hills or reload with quality bulletsand powders withlow deviations.
