If you are just punching holes in paper, try reducing your load to 7.5 to 8.0 grains of Unique.
OR, you take the other approach and don't adjust loads lighter for "punchin paper".
Somewhere over 30 years ago, after several years of different loads and bullets, I settled on one load and one bullet for all my .45 Colt shooting.
Yes, it is "excessive" for target shooting, on the other hand, EVERY ROUND I shoot is the SAME. No "adjusting" for different bullet weights and speeds. By using only "one load to rule them all" I've learned exactly how and where to hold to hit at any range from 0 to 200yds.
So, balance all the concern with shot to shot variations and data points against the "uniformity" one gets using only one bullet and load constantly.
Maybe I don't get the tiniest groups possible, but that's not what I'm after.
