The standard ADL 7RM has 1-8" also. I got one I'm making payments on right now.I see these will have faster twists like 1:8 for 7RM, good for the longer bullets but will they be throated longer too? If not it won't appear that it will help much. It would be nice to buy a reasonably priced, well made, accurate with modern bullets, off-the-shelf Remington 700.
