I shoot both the NAB and NLRAB in 260 REM, 270 win, 7 Mag, 300 RUM. ALL shoot excellent and are fantastic hunting loads. I measure all my OAL’s from the Ogive. I start .05 off the lands and work from there with .5 gm increments in powder.If so please post your method. I’ve shot hundreds of these things in various calibers and I just cannot get them to produce what I consider an acceptable group. I really want to run these bullets because they should be an excellent hunting bullet and I get outstanding velocities with them in all my rifles. I just havent found the magic trick to good groups with these yet.
This is yesterday’s example. 260AI with a 24” 7.5 twist Brux barrel. This barrel will hammer .25 MOA groups all day long with 140 Berger VLD hunting bullets. The shots below are (5) 5 round groups in a ladder increasing .3 grains at each target. The only one I deem even somewhat acceptable is the center target And I know the gun is much more capable than that.
