Knowing where it came from its most likely a 1in 8, that will be fine for 69 and 77 grain SMKs. If it a slower 1 in 9 it will still be ok with 69s and maybe 77s. Lighter bullets will be ok with either 1 in 7, 8 or 9.

Then try the 77SMKs. They are a great bullet and not much more expensive than the 69SMKs or Hornady or Berger of similar weight.
The 77 also seems to be more jump tolerant than the Hornady 75s, and you often get a fair bit of jump from the mag length ammunition.
