I'm in the market for a new scope for a Sako A7 in 270. I'm currently loading 140 gr NAB's at around 2900fps and want to shoot out to around 300 yards. This is primarily a whitetail hunting rifle. I plan to spend up to around $1200. I currently have a Zeiss HD5 2-10 on it but just have never felt it was as clear as it should be. I'm looking hard at the Swarovski Z5 2.4-12 BT. I'd really like some input on what would be the best scope for this amount of money for this rig. Thanks!
