That's my question. Most of my rifle brass is nearing the end of it's life and will soon be replaced with new or once fired RP or Win brass. I've read quite a bit on neck turning with some folks saying it's "absolutley essential with RP and Win brass (new or once fired)" to "it's a thing of the past, only reserved for match shooters with tight chambers". Before I invest in equipment I may not need,l what's the consensus here on turning necks for factory chambered rifles?
"Before I invest in equipment I may not need,l what's the consensus here on turning necks for factory chambered rifles?"
Consensus..? NOT likely! Lots of firmly held opinions with no clear proof either way.
FACT is, it doesn't do a lot for already loose factory chambers. But, done properly, it DOES do something to uniform the necks.
Second question, how much does it affect accuracy? There are no firm "facts" here. It helps, a little, for some, not at all for others. It's highly unlikely to make a vast difference even if it helps. Only way for YOU to know what it will do is to try it.
Most of the rifles I reload for I turn the necks on the brass. It doesn't take me that long, and it only seems logical to do what I can to get consistant neck release on the bullet. Some of my chambers are tight necked, some are factory, but I neck turn for all of my longrange rifles. Do I know it makes a difference in accuracy,no, but again it seems logical to do what you can to put the odds in your favor. At some point in the future I may grow tied of it, but for now it seems worth the effort. I have also gone to annealing after every firing. Again, it does not take much time, and follows the previously mentioned philosophy.
