Painless load development (mine)

It's once fired Hornady frontier if that makes a difference

No it doesn’t. You need to chamfer the case mouth. That is the solution

I figured. I appreciate it

I made 33 , that was probably the worst of them. I'll group them and post the results for fun

No problem! You’ll be dialed in no time! There’s only a few things are really important, and chamfering the case mouth (really just the inside) is one of them.

You don’t need “extra lube” after resizing. I only see issues like that if I forget either lube or chamfering. It’s most likely lack of chamfering, as just mentioned.

I've never seen such a thing and I have almost never seated bullets into intentionally lubricated necks. Rather, they almost always have lube tumbled off before prime/charge/seating steps.

I normally try to develop 2-3 different loads with different combinations of powder, primers, bullets. I will make my primary load then have a couple of backups in case i cannot get the components for the main load. Nice Rifle nice groups

This is what can happen if you leave lube in the case neck

Before I waste too many precious TMKs, how bad is this burr

Update:

These shot 10 for just under 1.5”

New starline brass shot 9 for 1.15”


And the training load that was recommended me on the other thread went 1.3”


With a bit of practice reloading and shooting, I just might have a nice thing going. Thanks for the help everyone
