First I'll start with I've had this rifle for over 5 years now and say it has been an excellent rifle; however, up until this past weekend, 8/9, I had never shot it beyond 350 yards which was on my first mule deer in Wyoming. I also took my first elk with this rifle and shot it sparingly throughout the years.
Through all those years, I've done a little work to the rifle: swapping out the trigger, changing the stock, replacing the handguard, and adding an adjustable gas block. (I shoot almost exclusively with a silencer and wanted to reduce gas back into the gun)
A month or so ago I found out about a smoking deal on Leupold Mk5 at Cabelas. I managed to get over there and score a 3-18 with TMR reticle for 50% off! So I thought to myself, well I've never really tested how far and accurate I could take this rifle why not throw it on their and give it a shot. (Pun Intended)
Enter this past weekend and the range I go to has the ability to shoot out to 1400 yards. In my mind, I thought well if I can get out to 800 with this rifle, I'll consider that good. I start small and hit the 400 and 500 yard steel gongs with little to no effort. I then decide to take it out 600 and 700 and again no issues. I then get to the 800 yard target and can still make good hits. At this point I am feeling pretty good about the rifle and decide what the hell why not go for a grand. I ended up getting several hits out to 1k, with low wind that day, and can't say how impressed I am with what this rifle can do. I wanted to go further but didn't have time due to needing to shoot some other rifles and spotting for other shooters. Will continue to push the limits of it and report back.
I say all the above as a testament to what the rifle CAN do if you do your part and what a value it truly is.
