    I have aquired a older marlin 44 mag with micro grooved rifling and I have noticed that the new ones have ballard type. Was the micro groove not good enough for the large cal. or am I concerned about nothing.

    micro-groove doesn't work with lead bullets, just jacketed ones, and the rise of cowboy shooting with lead bullets called for a switch.

    Mocro groove is another solution to a non-existant problem.

    You can use lead bullets in Micro groved barrels but they must be very hard (linotype) and probably need a gas check. Plenty of good jacketed bullets available.

    I prefer Ballard (cut) rifling as I cast my own bullets and don't want to experiment with a load just for one gun.
