[GLTaylor]

This is from 2023, not sure if it's the latest.

Note, this is outdated data.
Data sheets have been updated 15 times since January.
Current data posted under Hammer Hunter Load Data, post #8.

Y'all think I could try some RL-22 in a 7Rem Mag, 1:8" for the 169 HHs? or would it be a little fast?

Do it.

I used RL23 with the 131 and RL26 with the 177.

Is anyone shooting 182HHT from 300PRC? If so looking for your loads.

 

[LocalJW]

At what distance are guys shooting there pressure tests?

All charges above 80.7 had high pressures indicated because firing pin profile / diameter and diameter of bolt face FP hole was piercing or extruding primer cup into bolt face and proportional ejector swipe. Never experienced heavy bolt lift.
I have replaced complete firing pin assembly with Cre-Tan and when Gunsmith becomes available will have bolt face FP hole bushed. I hope to add 50fps to MV with these bolt enhancements.

Jasbo,
What primer and cartridge OAL?

Jasbo,

Sorry Geo! Primer is Rem 9-1/2M. COAL is 3.8765. I'll build a worksheet so I don't repeat these omissions. Thank you for managing Hammer load data.

Thanks for posting dustbag. That's going to save me a lot of work for my Dasher. Got Varget a Benchmark on hand.
