Well the last couple days has seen some mixed results.
I was so excited about tge 16 twist and I still am.
Had a few setbacks that I'm addressing.
First setbacks was a huge change in environmental conditions.
Showed that my barrel preasure point wasn't working out. As the barrel heats up it was pulling the action around distorting my groups opening them up considerably.
Showing up in longer range seasons
This became much more apparent after sealing up the load.
In essence creating a new preasure curve.
My thought that fixing the crown created a much tighter seal on the sabot making the burn much more effiecient.
After free floating the barrel it was much more consistent.
In that I'd make changes and the gun reacted predictably. Change back it went back to where it was before.
So basically I'm at square one and will fall back on powder charge and rework back up to find a node the current setup likes.
I also made another change but I'm not ready to share yet as I'm not sure it will work the way I intend.
More ti come tomorrow.
