Well like all of them your going to have to experiment.and other tips.
1/66 is not a normal TC twist.I am new to the site but after 30 years going to pull the Hawken round baller out and try to use it. Anyone have suggestions on a load and other tips. I have forgot most of what I used to know on it.
That is exactly what I shoot, but my Hawken has 1-48 twist. It has Lyman 17 front and 57 rear sights and shoots one ragged hole at 50yds. I love to prove peeps wrong at the range when they come up and tell that the 1-48 twist is just for conicals!!My wife's shot very well with 70gr of 3F, pillow ticking with spit lube, and .495 round ball. It was a Sharon 1/66 twist barrel.
