I have loaded many thousands of pistol rounds,going to do some rifle now.
neck sized some once fired 30-30 brass,and the .308 bullets are extremely loose in the neck.The ball is only maybe .002 smaller than the bullet diamter.
Leaving the expander ball out still gave the same reading.hmmm.
switched over to a fl die,without the ball,and the necks sized with that one are about .295. Much better,but is this 'too tight' do you think?
I'll be using the fl die for .308 jacketed and .311 cast bullets so dont want to remove any material from the expander ball.
upshot is?
should a .30 caliber necksize die resize to below the .306 reading?
AND
Is the .295 neck diamter that I get with the fl die so tight that pressures might spike,or is that good enough to use.It would give good neck tension.
sorry for the long possibly confusing post.
