Hammer Bullets Reloading Data

[cory]

I'm starting this thread to document my load work up for Hammer bullets. I'm planning an elk hunt out west in '24, so I'm in search of the best possible 6.5 Grendel hunting bullet on the market for my 16" Precision Firearms Bartlein barrel primarily and my 11.5" Lilja barrel as secondary. All intelligent discussion is welcomed as well as any load, range, or on target data anyone has for cutting edge bullets.

HB Absolute Hammer Bullet 109gr
Not great results on target, but I'm not ready to give up. I'm going to make some adjustments and take it back to the range focusing on the 11.5" barrel for this bullet.

HB Power Hammer 115gr
This one shows promise, but the 109gr and 123gr Absolutes have done so well I don't see much reason to invest in this one any further. I do have a handful of bullets left, so I'm going to load up another small ladder to take to the range for more data if nothing else.

Long overdue range trip and update. I have high confidence in the velocity data this time. I was running a Labradar and had the opportunity during the day to run it next to a guys new garmin. The Labradar consistently ran 3-5fps faster.

Unfortunately the brass was showing signs of pressure at 32.1gr, so I'm going to back off a bit. However, 30.9gr to 31.5gr shows a lot of promise. I'm going to load up an OCW and head back to the range.

The brass was showing signs of pressure at 32.2gr, seems to be a trend. 31.3gr to 31.9gr showed a lot of promise. I may load up at 31.2gr, 31.5gr, & 31.8gr and head back to the range with this one.

The brass showed signs of pressure at 33gr, so I'm going to back off of that. 31.8gr to 32.4gr looks like a node. I'm going to load some up at 31.9gr, 32.2gr, & 32.5gr and head back to the range. I think I'm going to focus on the 11.5" rifle for this bullet.
