Today I finally got around to shooting a few groups with a new load for my 24" Eabco barrel in 6.5 BRM. I wanted to see how it would respond to a combination of SW Precision powder and the 129 grain Nosler LRAB.
The load I settled on is churning up an average of 2522 fps (uncorrected at 15 feet). I fired two 3-shot groups at 200 yards with this load and was rewarded with eye-popping groups. The first measured .790. I wanted to make sure that was not a fluke, so I let the barrel cool and fired another three-shot string. This group was even better at .644. I'll try and get a couple pictures tomorrow if I remember.
The 129 grain LRAB is an interesting bullet. It's extremely soft and sheds weight rather quickly. But being bonded, it maintains enough mass to keep plowing forward.
In my own testing, the 120 grain Ballistic Tip out-penetrates it and retains more weight when both have impact speeds of around 2300 fps.
Hopefully I can place one into a more interesting medium before long...
