LE,
what barrel twist rate are you trying to shoot them with? What seating depths have you tried? AR or bolt gun? once fired brass? new brass? unknown number of reloads brass? Same lot/brand brass? range scrounge brass which may contain various mfgr and unknown variety of lot numbers?
Something you didn't mention in the initial post was any seating depth test. if this is a bolt gun it's easier to load jammed, just touching, and off the lands by 0.005", 0.010", 0.020" etc. to do a ladder for seating depth.
if an AR you might, and I repeat maybe might, try a seating depth ladder loading singly and not from a magazine. use the cocking handle to lower the bolt slowly and the forward assist to insure fully seating the round. If an AR you might find, unfortunately, that in your particular barrel/chamber that the accuracy node is at a COL that is too long for magazine feed. It can happen, though with a lighter bullet, hence a probably shorter bullet, I would think exceeding max COL for magazine use before finding a potential accuracy node would be lower probability.
depending upon bullet ogive profile (secant, tangent, hybrid, etc.) and bearing length you might have to touch or jam to get them to group well, which can be acceptable for a bolt match rifle, but for bolt hunting or AR is a non-starter for any use except for an experiment to find an accuracy node.
Also what barrel brand are you running, if known? Do you get good accuracy with this rifle with other bullet/load combinations? Just trying to think through some more variables for you to work through in the attempt to find a load for you that gets these bullets to group through your rifle. I don't suspect bad bullets, but something else in the load/fit for your rifle.
best regards,
