.350 Legend loading issue

[RonW]

Is there a trick to this? I swear I'm banging my head against the wall trying to sort this out, Lee Dies, including FCD, new Star-Line brass, Hornady .355 170gr bullets. the brass gauges perfectly before loading with a Lyman case gauge....yet when I drop the powder, seat the bullet, and lightly crimp it, it fails the case gauge. I have tried adjusting my dies time and again....There is something I'm missing here...is it possible there is something unique to the .350 Legend in terms of loading?

It could be too much crimp, and it is buckling the front shoulder of the case.
I would try one in the gun itself, and see if they chamber.
If so, it could be just a tight case gauge, and you may have a bigger chamber.

The rifle runs perfect on factory loads...no issues, I am seeing a bit of a bulge in the case where the bullet is seated.

Just spent a little time with a set of calipers.....my reload versus a factory load, the only area I'm seeing any real measurable difference is at the base of the case, just above the head, I measured .485 for the factory load and .492 for the reload. rifle will not chamber the reload.

I use the same brass with RCBS dies and haven’t had any issues. I can’t speak to setting up Lee but I could do a video this weekend on how I set my dies up if you think that would help. Let me know.

that would be helpful, thanks.

Cool I’ll do it this weekend. It’ll end up being something simple. I had same issues with 30.06 and it ended up being something simple.

I guess you are seating and crimping in different steps with a FCD? Can you chamber a case in your gun just before you add powder? If the brass chambers nice then, it has to be something in the neck area that changes with seating and crimping.

After playing with it for a while....I've just come to the conclusion that a small base resizing die is probably what is going to solve this issue, anything I ran through the Lee die will not chamber.

That is strange. I load for the 350 Legend as well and use Lee dies. I have no issues with chambering. What gun are you using? I have the Ruger American bolt and it run fine.
