Just curious what rifle and glass you are currently consistently making 600+ yard hunting shots with? Sounds like maybe you don't need anything better?
Browning A-bolt 7MM Rem Mag, with a Crappy bushnell scope. I have had it for at least 10 years and have learned alot for using it. It replaced my 270 and 30.30 before that. The camber is very tight on the rifle and why I had to get it to a gunsmith because it developed a bur and I could barely extract a casing without a lot of force.
The scope sucks in low light and needs to be upgraded. I am looking to find something for it but right now it works so I use it, but I would like to replace it with something a lot more custom to me and not quite so off the shelf.
