7-30 Waters from 30-30

[Leadmelter]

Hello Group
Making some 7-30 Waters from 30-30 Win. I used a RCBS forming die and a RCBS FL die set.
What I got is a Coke bottle case with a 7mm neck. I plan on blowing the case out with H335 and some J bullets.
I the cases fit into my TC Super 14 barrel. I just formed some 7mm TCU but that seemed more straight forward.
Am I on the right track?

I formed 7-30 Waters from range pick up 30-30 cases years ago.I did not use a form die. Just a FL size die. Ran the case in to form a false shoulder that would just let the barrel close and used a moderate powder charge with a cast boolit to fire form. Worked perfect and I am still using the same cases at this late date.

I did the same as TCFAN except Jword bullets...and a moderate load of H335. Full length size and fire form. My next batch I am going to anneal after forming. I have been loosing too many to split necks after a few loadings.
