Bobby Hoyt made a .45 barrel for me and recommended a 1:56 twist. The accuracy sweet spot is around 55-60 grains.
You are probably good with just about any of the typical rates for a 45.Oh, just for matches, paper and sillhoettes.
Maybe there is something to be learned there.the green mountain Kibbler barrel in 45 has a 1-72 this is one of the reasons i asked. i have built several of them and in the middle of one now and have another on the way. this is the SMR i speak of, they shoot good with 55gr. of 3f, but i really have no idea why Jim went with a 1[72 twist in a 45 barrel.
