I do as well. Used to do 100 but started doing diagnostic tests at 300 last fall.Thanks to be completely honest it’s only the 3rd time I shot groups at 300 yards but I was shaking slightly after my 5th shot. I shoot PRS and have implemented doing my load dev at a minimum of 300 yards.
Can anyone attest the lot to lot consistency of the DTACs? I am wanting to shooting these out of my new 6 Creed I’m currently piecing together. It would really help the back pocket out if I could just order 1000 instead of 1500-1800 for the barrel life. But I would hate to gamble and end up having to waste more rounds on a second load development when switching lots.
Switch to H4831SC.

SD/ES numbers aren't the best (sd ~8/es ~20) but I think the new brass has a lot to do with that.
Right now I have 1200rds down and shoots 1/4”Any info/historical data on barrel life for you running there. Im at 3100f/s and thinking of pumping the brakes a little and getting down in that range.

My buddy with the same barrel shoots them at 2950fps, and he’s at 1875rds and still shooting great (6creed)
