My 54 flinter is 1:66, and is much more than sufficiently accurate for deer. Five shots at fiftey yards is one ragged hole if I do my part. That's largely due to the peep sight helping out old eyes.
The rule of thumb for 54 cal is 1:48 is conical (Maxi ball) twist.... 1:66>1:70 works well with round ball, either .530 or .535 depending on the gun.
Remember.... they're full time deer......we're part time hunters!
