It is 251 Falcon as engraved on the barrel. I did a cerrocast of the chamber for some measurements before I started forming the brass. I tried forming 32-20 brass but got an unacceptable number of case collapses (I think an intermediate die between .30 and .25 will fix that). I ended up using 25-20 brass, which I only have few of. These were on the very low end since I was fireforming the cases, 1200fps. Bullets not fast enough to stabilize?

If that barrel has the 1 in 14" twist, that bullet probably.
