[QUOTE="emp1953, post: 2020910, member: 71817"] These targets were your 100yd targets? or your 400yd targets? You have an approximate 2MOA at 100yds. Group 1 shows an elevation spread, Group 2 shows a windage spread. If that is truly the grouping of your rifle with this load at 100yds, then these spreads will increase with distance. The MOA's do not change with distance, the "inches" change. I shoot a SIG 970shr in .270Win. Shooting 150gr Nosler partitions with 51gr IMR4350, seated 0.020 off the lands, velocity chronographed at 2884fps. I have 0.5 MOA at 100yds on every group. I have shot and killed whitetails consistently out to 600 yds. My scope is also mounted on a 20MOA rail, so I can dial up quite a bit. The scope tracks consistently and always goes back to zero when dialed back down to my 100 yard setting. If you have a range to shoot at 400yds. put up a 36"x36" target, aim [U]dead center[/U] 5 shots and see what your grouping is. 1MOA is actually 1.047" at 100yds. If you shoot a 1MOA at 100yds which is a 1.047" group, then at 200yds it is 2x1.047, 300yds is 3x1.047 etc etc. So with your 2MOA grouping its 2*1.047" = 2.094" at 600yds your spread calculates out to 2.094x6=12.564" . So at 600yds you could easily not hit the deer at all. Your Tikka is capable of much better accuracy than that. [/QUOTE]
