http://www.lasc.us/FryxellMarlin-MicroGroove.htm As stated the Marlin rifles with the shallow lands and grooves need a larger dia. bullet that completely fills the grooves and cast from an alloy that is at least 12 BHN or higher to prevent bullet slippage on the shallow lands and grooves, a gas check bullet is always a plus with the Marlins that have Microgroove rifling.
NOE, Accurate as well as Arsenal Molds all make excellent molds. NOE and Accurate are about on the same price level depending on the number of cavities you want, but Arsenal molds are a great bang for the buck I can get a 4 cavity .311 170 gr. FN 30-30 bullet of the Ranch Dog design which is a great hunting bullet shipped for the price of the NOE or Accurate mold in a 2 cavity.
I plan on purchasing this mold in a couple weeks for my Savage 170 30-30 pump gun
