I have started to develop a load for my 243 Predator Max. It took to the 87 V-Max and H380 right away, shooting less than an inch with a brand new rifle. I sized and neck turned the cases to a nice consistent thickness before loading. I have two loads I am zeroing in on, one is about 95%, and one is about 90%. Both group well, but the 90% load is going into 1/4 inches for three rounds! I noticed that load has smoky case necks.

Anything to worry about?

I don't mind a little extra cleanup for better accuracy. I am expecting the smoky-ness to go away once fire-formed.

Any opinions?
