I anneal my brass, then size it, then trim it. This way you get a true sized case because the length will change when you bump the shoulder back. Never had a problem doing them this way.
I also pull my decapping pin out of the sizing die.
Thanks, I follow the same process you do with my fired cases. I also start with a Mighty Armory universal decapper and use no decap pin in my size die

So, like stonehenge says, trim all to the 1.480, then take maybe, 10, shoulders down to 1.183 as necked down cases. When the barrel comes in, you’ll be gtg with 10 to test with. This of corse assumes you have the hornady case comparator and B (0.350) insert, along with calipers. Additionally I’d keep on the lookout b/c you can still find a box or 2 or 3 of the 105’s and add them to your stash.
Correct, no barrel yet. Good point to trim first and no more then 10 cases. I do have the comparator and .350 insert.
