DeerHunter is correct, Marlin 1894's in .357 mag and .44 mag do not have Micro Groove rifling. They have standard "Deep cut Ballard Rifling" (standard rifling). For some odd reason though the new .41 mag model does have Micro Groove rifling. Between the Marlin and the Winchester I prefer the Marlins. I have a Winchester 94 30-30 and a Marlin 1895 LTD 4 .45-70 and also a 1894CS in .357 mag, I shoot the 1894CS in .357 mag more than the others and love it! it is a tack driver and .357 mag 158gr loads out of the longer rifle barrel nearly put it in the same league as the .44 mag 240gr loads out of a 6" revolver.
