[QUOTE="AKGuide, post: 768273, member: 64701"] Just found out my 28" Pac-Nor .338" neck 300 Rum loves the 240s and H50BMG. I was shooting the 220s with retumbo at 3057 but getting vertical at long range. With the 240s I loaded them from 90 grains to 94 using virgin nosler brass with GM215Ms with no pressure signs and would say they may be a little mild. OAL was around 3.655, i use a rcbs mic gauge for testing length to lands. Although with 92 grains and kissing the lands it shot sub .25 moa with a velocity of 2907 and an es of 1 with a .5 sd. These are HbN coated so my data may be a little different from naked bullets. At 94 grains they were going at 2950 but the es and sd were higher es 11 sd 5. Have to adjust a little more for elevation than the 220s but the wind bucking ability of the 240s makes up for that. Now i need a keg with the same lot number, fingers crossed. Just thought I'd share. Reuben [/QUOTE]
