Browning X Bolt 1 in 9 twist 26”
80 grains H1000
Grouping OK at 100. At 200 and 300 I’m lucky if 1 bullet hits paper.
Could the bullets be heating up and disentegrating? Seems like they should be stable ~3200 fps at 600’ elevation.
Scope and rail are torqued down.
Any ideas or suggestions? I’ve got some 180 Bergers ordered I was hoping to make these Hornadys work with their higher BC.
