Very nice group…I love CFE, its one of the fastest powders for 223 and its produced some great groups for me as well….
But, sadly it is not temp stable and loads will fluctuate from day to day, but very very accurate when its dialed in for conditions. If you are experienced enough to play around with + or – powder charges for changing conditions you will be very happy with that powder / bullet combo… I only shoot it in the summer months. I love the increased velocity it gives you over Varget…but Varget is still my favourite for my T3 Varmint….25-25.5grs pushing a 60r Nosler BT Spitzer, not super fast but deadly accurate any day of the week.
Good shooting. Would also love to see some cold bore testing like Eric mentioned if you can put the time in or remember at the range. Would be a nice case study on the powder.
