Hello i am new to reloading and need some help. I reload 6.5 Creedmoor with "Redding Type S Bushing Neck Die". I use Bushing size .288 without redding expander button i get 0.010" of neck tension. Accuracy is very good. When i attach redding expander button i get 0.003" neck tension. Is 0.010" of neck tension too much and should i use Expander buttton. Thank you!
