my new 220 swift is 1-12 twist in my new Ruger #1 ,that I had Greg build for me 26 inch barrel, I plan on using 60 GR. Nosler Partitons for coyotes and maybe even deer ? 220 swift is sighted in using H414 for now, shoots 3 shot groups are 3/4 groups. once its cold after the deer seasons, I plan on trying some maybe cold weather powder so case is very full for good ignition once its cold.after about 20 shots I did put a rag thru the barrel with wipe - out bore cleaner no brush,that will be the last time I clean this rifle tell spring some time . Berger`s book say`s 1-12 twist is best for 60 grain bullets so that`s what I used ,right or wrong ? I did
