I thought i had a couple boxes ill look again tomorrow to make sure. I do have 2 boxes each of 145 lrx and 168 lrx if you have any interest in those. I also have 19 left of the old 140 mrx.
Try 155 to 168 gr bullets. I have a newer m70 ultimate shadow 1in12 twist first tried 178 eldx factory an168 fgmm neither would shoot. Tried 155 a max, the new 155 Browning stuff and 168 a max. Shoots all 3 lights out. Although I was hoping to run the heavier bullets
