I'm glad the 124's did well, but something isn't right here and I need to know what it is. May I ask what your oal is on the 147 grain load? If you drop-test, is there any contact between the nose of the bullet and the rifling?
You should still back off on the 124 crimp. It's too much.
Last question; do you live anywhere near the GTA?
Scarborough and Northumberland is my home club.
Here is my data
- CZ Shadow SP-01
- Max. OAL with AIM 147gr touching rifling is 1.095"
- Seated bullet to a OAL of 1.085" +/- .001"
- VV N320 3.7gr
- PF of about 138
- Mixed brass
- Fed #100 Primers
- No crimp... just enough to remove bell
