Tried neck sizing with a FL sizing die for the first time and have a few ?s. The gun in question is a 204 Ruger M77 MKII Ultra light with about 200 rounds through it. I'm loading a mid-range load of Benchmark with 35 gr Bergers well off the lands.
I backed my die of the base of my shell holder about 1/16 of and inch and sized a few pcs of fired brass. than I backed the die out to 1/4" off the shell holder and did 3 more. After trimming to length I loaded them with bullets only and tried them in my gun. The rounds chambered with just the slightest amount of fliction. The 3 least sized??? gave just a little bit more resistance than the first 2. Is this normal or do I need to bump the shoulder back a bit? The cases where polished prior to sizing and had very faint marks on the side's running the full length of them all the way around. Rough chamber? It is a fairly new rifle with less than 200 rounds down the pipe. It was doing this from the start (scratches) with new and fully resized cases but it went away after about 100 rounds.
Any help would be much appreciated,
