My Marlin does well with a cci200, 38.0g or Re7 and the 200gr Sierra bullets. Only have used inside of 150 yards but they have pretty much been bang-flops. Shot one deer head on at about 60 yards and bullet blew through and exited a ham but did not get all the way through hide. The rapid drop was something to behold.
What brass? I've found a noticeable pressure difference if I use WW or Starline. The Starlines are heavier so less capacity, higher pressure.
