[QUOTE="Trig, post: 1645176, member: 74813"] here is some load data i have worked up in my rifle. Rifle specs, Stiller Tac300 Brux 1-8 28" 4 groove + break Manners T4A Badger CIP length dbm with 300 WM mag boxes (3.775 max aol) Timney 501t trigger The rifle is chambered with saami min spec reamer and throated so there is approximatly .300 of bearing surface seated in the case with the 195gr EOL bullets seated .020" off the lands. After running a very mild load of AR2217 (h1000) for the first 100 rounds i switched to AR2225 (Retumbo) and did a ladder test at 300m with powder charges running from 68gr to 70gr resulting in a reasonably flat group (was a little gusty wind from right to left) velocity for these was, 68.0 - 2863fps 68.5 - 2895fps 69.0 - 2926fps 69.5 - 2929fps 70.0 - 2958fps Seeing that the velocity between the 69.0gr and 69.5gr loads was only 3fps different i decided to load some test rounds at 69.2gr and shoot them at 1600m for fun. final load is, Sako brass F215M primer Berger 195gr EOL 69.2gr AR2225 3.624" OAL (Warning these loads may not be safe in your gun as they were developed in my rifle with long freebore) shooting the AR2217 load at around 2800fps required 16.6 mil from my 300m zero to get to 1606m switching to the AR2225 load at 2920fps required only 15.4 mil to be on at 1606m although i only fired 2 shots at the plate the vertical dispersion was only about 1" [URL]https://imagizer.imageshack.com/v2/640x480q90/923/uNhgc2.jpg[/URL] [URL]https://imagizer.imageshack.com/v2/640x480q90/924/iiujCN.jpg[/URL] [/QUOTE]
