More info would help. If your going to start shooting matches I would go with a First Focal Plane scope. Depending on the budget.... The Schmidt Bender 5x25 is the best you can buy IMO. It will do nothing but increase in value and it is a fantastic optic.
If I was going Second Focal Plane I would purchase the new NightForce 5x25 Atrac scope. It is suppose to have better glass than the older NF scopes. IMO that has been the biggest problem with NF. They track perfect, are bulletproof, and are a great optic. BUT....The glass has never been great. Just OK. Im hoping the new scopes live up to the hype.
BTW.....Im putting a 5x25 NF on my 284 Win that Robert and I are putting together
That ole boy sure can build em
