Shopping for a Lyman M expanderdie for a 25-35.
not sure which one would work. Have one for the 25-20 but too short. Could use a Lyman expander for 30-30 also. Would the 25-20 expander with stem work in the 30-30 lyman M die so as to kill 2 birds with one stone....Thanks

I have a set of 25-35 dies that I obtained to use as case forming some 30-30s down to 22. I'm not sure if the stem and threads are the same length,size as the 30-30. I can check.

Lyman lists one for the 25-06 and 257 Roberts (#7349057). I think it would work for the 25-35.

UPDATE : Bought the Lyman 30S expander die for 30-30. The 25-20 expander threaded into the 30S die perfectly and works great.
