I currently have a 357 Max Handi that I reamed, no problem! Easy as can be. I will likely be having a 44mag barrel fitted to my receiver sometime after the first of the year, of which I plan on reaming out to 445 SuperMag. I was disappointed in the dimesions of the 357 max reamer as it has a cone shaped throat, which doesn't guide or support the base bullet on the way to the rifling. My gun will only shoot long bullets, 180xtp's and 200gr RN bullets accurately.
My question, does the standard 445 reamer have the same cone shape throat or has someone here had a custom reamer ground that has an appropriate throat? I'm either looking to rent one with appropriate dimensions or have one custom ground. Any help would be greatly appreciated. Thanks!
