Home Forums Reloading Big Game Rifles Opening up a 7/8x14 press to 1 1/4x12

So has anybody done this. I have used my 7/8x14 Lyman press since the late 70's and only now may have a need for a 1 1/4x12 threaded press for the larger dies needed to reload a 577-450. I wondered about having the press opened up for the larger dies and having a bush made for the standard 7/8x14 dies. I can trade off the work with the engineer for some other works he needs done.
There will be a reasonably large investment in the rifle, dies, brass and a mould to cast for it and a new press would take the whole package into the too expensive category for just one rifle.

I just use the big Simplex O frame with the insert that can be screwed out, there should be a bucket load of them in NZ.
