I opted for the Lee trimmer system as its easy..
You could/I could trim too 2.030 if I wanted but my l e Wilson ultimate trimmer is set up for my 7mm 270 which I do trim 5 thousandths less off the max trim length.
My saum has done about 1750 shots so far and still shooting nicely..
I'd be happy to make 2000 shots before I retire it..
Shooting the long-range challenge in a couple of weeks which reaches from 1000 out too 1200yds..
The 184s have served me well out that far
