I am looking for a 7mm improved round for long-range shooting (600yds-1000yds). I am interested in any information on what's available outside of the magnum cases, I don't want to buy another bolt body. I know the 284 Shehane and the 280AI are out there but I would like to hear suggestions, likes and dislikes of everthing for 165-180 gr bullets in this caliber. Thanks for the help, and I look forward to hearing everyones input.
