I've heard this neck tension argument many times and it just don't hold water.....maybe if the trim variabce was a quarter inch.....but .010?????

Consistency is a great goal.....but somethings just don't pay back...

Among them are weighing every powder change to .1 grain!!! Uniforming flash holes and uniforming primer pockets.....turning necks for hunting rifles that don't have a tight neck chamber....and trim lengths to "exact" lengths.

Layne Simpson reported it a long time ago....unless your rifle is already shooting 1/2" groups....these things do nothing for you.....and I looked at what he said and thought....yup....this matches my experience exactly.

Further.....the huge majority of hunting rifles that shoot 1/2" groups are shot on the internet.....not at any range!
