I am sure this has been covered before, but I googled around and couldn’t find the answer I was looking for.
I am using a bushing resizer for the first time. It’s a Redding Type S FL bushing sizer. I am necking 6.5 Creedmoor down to 25 Creedmoor. I have Alpha brass that I will use for actual cartridges, but I tried resizing some 6.5 Hornady brass so I don’t mess up my $1 a piece brass. The neck thickness on the Hornady brass was ~0.0135. So, by my math, [(0.0135+0.0135)+0.257)-0.002=0.282.
When I use the 0.282 bushing, however, it comes out to 0.279. I am using Hornady Case Lube and I cleaned the die&bushibg before using. Obviously the expander mandrel and decapping pin assembly is removed.
What could be causing the die to size the neck down 0.003 more than the bushing size? Is it possible the bushing is wrong? Could there be too much lube on the case necks taking up 0.003?
Any advice is appreciated!
