Awesome, thanks. It's still a little too chilly up north for that kinda stuff.

 

Cheers!

 

I'm heading to up Fairbanks for a few weeks. I'll have to chrono it when I get back.

No worries.

 

I've already loaded and shot 17gr. It felt and performed identical to 16.7gr, which was to be expected. Still no visible signs of pressure.

 

Next up, 17.7gr! Yahoo!

I'll need to independently verify the data, as I always do, but Joe4d laid the foundation for my insane quest to pump as much 296/H110 into a .357 case as humanly possible.
