I mostly load pistol rounds, 44 mag, 357 mag, 38 specials. I aint ever loaded rifle rounds to where the primers were loose so I aint got that to go by.
What I get though with pistol brass is an inconsistent feel in primer seating.
Most recently it is with new starline brass in 44 mag. Loaded only a couple times, and both lighter loads. I loaded them again today, and there is quite a bit of difference between some of them. Some are normal, a few tighter, and some are pretty easy to seat.
I've used a hand prime tool and I could really tell a difference, and now I use a lee ram prime, but still have a good feel.
So what do yall have to say bout this subject?
