Hammer HHT Load Data

[GLTaylor]

OK, folks. Finally got some data on the new HHT bullets to share.
I'm sure this will grow exponentially as people have time to develop loads and share results.
Remember to post your results on the "Share Your Hammer Loads" thread please.

Happy Groundhog Day!

300PRC
182 HHT
24'' 1-8 Twist
ADG Brass
CCI-250
3.562
RL-26 81 Grains three shots as follows...
3251
3251
3249

I started at 79,80,80.5,81,81.5 and 82

I had swipe at 82 and that round left my nice neat .75 group so I dropped back to 81 and shot a .6 group.

I didn't record velocities during my pressure test. That is one too many things for me to manage.

This rifle shoots groups like this very consistently with Hammer Hunter 152 grain (57.0 grains Ramshot Big Game and 166 grain with 61.0 grains of Ramshot Hunter). I barely had to do any load work up. Pretty much the first few loads I tried shoot like this. This rifle really loves the Hammer bullets and load work up was a breeze. I just used my regular 152 grain Hammer Hunter load with the HHT's and it shot like this on the first time. Haven't tried any other load combo.

Has anyone measure HHT BC in there rifle compared to similar weight Hammer Hunter? Any improvement in this area or only in impact performance?
