So here is the situation I am building a new house and going to have a 400 yard range out my reloading room window. That being said I have the bolt guns I need 223ai ,6dasher,and 6creed and have a Odin works 6.5 grendel. I was thinking about getting an M1a but people say I have to spend 3k to get a 1 inch group out of one so I was hoping you guys had some input on something under 3k that shoots 1” at 100 or better the max I shoot is out to 600
