Looking at 22 creedmoor dies. Almost everyone offers a bushing die with a micrometer seating die. RCBC and Redding are the 2 I mostly looking at. Whidden offers both non busing and bushing die. I understand getting the proper neck tension on the bullet with a bushing resizing die. Is it truly something worth it though? New Peterson virgin brass is on the way. But what bushing would I need for a .224 bullet? I have no loaded bullets right now to measure off of.
