I have been looking at a coupe of old marlins @1 is a 1971 Zane Grey Marlin 30-30, 22" Octagon is this good match for a ranch dog 165 cast boolit?I am not sure if it is a micro groove or not.#2 is a Marlin 336LTD 30-30 Limited Edition. I am guessing this one is a micro grove. I all so wood like to shoot the ranch dog in this one too . I also have a Winchester 30-30 ae that I want to shoot cast with. I have heard that the Winchesters throats wont feed the ranch dog booolits.I saw that NOE has push thru sizers that will let you nose size your boolits. wood this let me use a ranch dog boolits in my Winchester>. I wood like to use the same boolit in all 3 good luck with that. thanks for any insite you have on this. happy casting in 2016 PROPWASHP47
