I had a 4" Taurus 66 . "If I knew then" , oh well . It shot 38s and P+ great tip into 357 loads and it opened from useful to get off of me . Start loads of Blue Dot showed much promise but it took a hammer to get the cases out of the cylinder .
Make no mistake it was a great gun beyond that , it shot well , felt good , and I liked the way it carried . I think in hindsight the throats were under sized and possibly even the barrel , I wasn't shooting case then but I did shoot a lot of 158 Speer HP . The one that tipped me off though , 5 yr later , was the gift of a bunch of 85,90,100 gr Gold Dots . Of course no data for anything that light in 38 or 357 but 110&125 was found in the then new 47th Lyman I think . Beautiful to shoot not good for anything but paper , being for 380 ACP . In cast I likely would had sized down or just bought a 356-147 RF and gone to town .
It was smooth and tight it just wouldn't wouldn't shoot 357 loads .
