That is outstanding!
SD of 7...wow.
I think you'll be in good shape when things warm up. I shot some maxish loads at 90 plus degrees, and all was well - but check it for sure at your elevation/temp/etc in your rifle, of course.
What charge did you settle on - seems 50ish is a pretty sweet spot from what I can see so far for the chronograph-less old timer low tech loaders...grin.
I really gotta get one...
