When every I start working a load on a new load for a new rifle, I try to find the projectile that the barrel likes the best. Just becasue your last (Rifle type) like one brand of bullets does not mean your next one may not like that brand or that weight.
I would love to have the makes produce a trial pack of 15. I could build 3 groups of 5. If I like the proformance I will buy the boxes, if I don't like them I am not stuck with 85 bullets that do not profom in the gun.
I have lots of pactical boxes from what I though would work, but the gun does not like them.
Have a good day
