Re: advanced reloading techniques
So I realized I only answered half of your post.
Primer pocket uniforming tool (recommend powered, because manual gets exhausting)
Flash Hole debur tool (manual is ok - you'll only do this one time)
A quality Case trimming tool.
Powder Trickler *I use an auto powder dispenser and verify every tenth drop with a beam scale.*
OAL Length Guage
Dial Calipers (bought for a reasonable price at an auto parts store)
Comp. grade dies ( I own just standard RCBS dies. They work ok, but leave a lot to desire)
I don't own a concentricity gauge, nor do I neck turn. Just haven't needed too is the reason.
I'm sure you've heard "consistency equals accuracy." The same applies to reloading.
If I forgot something someone will let you know.
