However,the representation is Marlin rifling profiles,I have heard and read many posts stating various knowledge and apparently ACCEPTED beliefs about these two types of rifling,but never have I seen mechanical drawings with dimensions side by side for comparison,one older thread had two posters one said Ballard rifling had deeper lands another said microgroove was higher(?!) No one questioned or corrected either ,so maybe both were right?
I have my own ideas and abilitys far below those of mortal men but have never seen mech. drawings to compare and if someone could share these here I would,along with others of my I'll ,enjoy this .
I am presently delving into the casting world again using my Marlin 336 and my 1895, both microgroove,and my 1893 which I assume might be the original Ballard rifling but they never said so then unless I did not hear them.
These drawings would be good even if they are not factory original,just true representations,thank you.
I am presently shooting Lee .460 día. .405 gr.HBFP over 40 gr.IMR 3031 when I get to the range and trying .311 150 gr. GCHP
30/30 over .22 gr. H 4895 ,in my 336 for the first time for 30/30 cast.,for those interested this load reduction was double and triple checked through Hodgden tech support, and is only recommended and approved with H 4895 -specifically -ImR 4895- has not been tested or approved for this load and any such load is NOT approved-Hodgden tech support.
