So far I've only looked at K&M and the 21st century. This will be for a 25 Creedmoor. The reason will be for a tight chamber. It's on the line where with if everything is just right you don't need to turn. I'm breaking in barrels, & may not have done a perfect job on drying the bore. There was heavy bolt lift. Load light at 41.0 grains H4350 for break in.
I'll be calling K$M & 21st century asap. These days not always easy to get through to businesses. While waiting I would appreciate your cost estimates for the various equipment, your opinion on ease of use, and the consistency of results. Thanks to all for reading and sharing advice/experiences.
Reamer print bore neck diameter = .290
Fired brass neck OD = .28885 - .289
Virgin brass loaded neck OD = .286
This is Peterson brass head stamped 25 CM.
New neck wall as measured = .0125 - .0135
All measurements with Mitutoyo tools, Peterson brass, & 135's. Barrels are the Bartleins with the harder steel. 1 SS & 1 CF. Both M24 w/ 8-7.4 RH twist.
