I understand not wanting to spend 3k in a rifle when you are starting which is fine. My "custom" 7mm rem mag is around 2k and shoots .2 at 100. Im sure it will do better with a better shooter. What are your expectations for your rifle as far as accuracy? Stock I will say you are looking at 1.5 to 1 inch if it is all right. Once you get that you will have to start upgrading to get that number to shrink. Pairing with an experience shooter will be best. I have got a lot of good info at the range talking to the guys that know what they are doing. You will find many wannabes that talk more than what they shoot. Look for the guys that are shooting and grouping good. Generally those are the guys that if willing to help will give you great info. Check with the range master, he generally knows who is bsing and who is real...
Good luck.
