[QUOTE="MallardAddict, post: 2559060, member: 3830"] I’ve owned a few 28 Noslers and now my 300 NMI. The 28 is a wicked nice round and never left me wanting but it’s very hard on barrels and throats grow quickly. The 300 NMI will shoot a heavier bullet with similar speed and ballistics with more energy on target but is much nicer to the throat area while still having similar recoil and rifle weights. The down side of the Norma is the Lapua bolt face and the somewhat limited actions that use the bigger bolt and lugs that the Lapua/ Norma case really needs The ideal 28 powders are things like R33 (carbon rings fast) or the N series of powders which while fast and consistent are harder on throats then h1000 or Retumbo. The same holds true using it in the NMI but the shoulder on the NMI holds the flame back longer so it’s less exaggerated. In both my NMI and 28’s I chose to shoot Retumbo as it’s nicer on the barrel and doesn’t give up much speed. In my 300 NMI I am shooting 88.5 gr Retumbo with the 230 hybrid at 3100 fps. Sd’s and ES are almost always single digits and groups are sub 1/2 MOA with boring regularity. I’ve played with the 199 HH and had it around 3250 fps and showed promise but so far I’m sticking with the heavier hybrid for my uses. [/QUOTE]
