Went out yesterday afternoon to do some shooting. I thought this would be a perfect opportunity to try my new Leupold 6.5X20X50 MK4 TMR on my SSG built 338 Lapua Improved. I was really impressed with the the new MK4, especially the TMR. About time Leupold switch to glass itched reticule. I like the way Leupold designed the TMR. It is almost like an IOR MP-8 dot reticule except the dot is missing. I like that better! because there's nothing there to obscure the target, especially when aiming at small target. There is also a vast improvement on glass coating on these new MK4. I could see the difference when compared with the old MK4. Overall, I'm very pleased. I mounted the scope on a pair of Seekins 6 screw rings and off to the range I went. After zeroing the rifle, I placed my steel target to 525 yards and fired this 3 shot group. My load consist of 95 grains Retumbo, 300 grain SMK, Federal 215M on Lapua Brass.
