I like them in my 9 twist montana. They are the best pitch going for it. 77s tmk and 75 elds are a no go in it.
Wish I could find some more 69 TMKs as well.
I just got 1k of Rocky mountain reloadings 69 smk clone. I'm sure they will not have the same performance of the TMK but should be similar to the SMK plus the price is great and they are available
