Posted a report under Politics called Ammo is available about buying .41 magnum online, which was an experiment - 230 grain CBs. Tested in the carbine, they grouped in groups cutting each each previous shot at 25 yards, except 2 out of 10 which seemed out due to slight tipping.
Tried another experiment today, got out a box of heavy bullet loads: NEI-SSK 411275 TCPB which cast at 295 grains, 18.0 grains H-110, CCI350 primers. Loaded in Feb 2002 for the Marlin and the Ruger Redhawk. Wanted to see if a magazine full of rounds made any difference in point of impact. (The Marlin 1894S holds 1 chambered and 9 in the magazine). Not so you would notice - I shot the 10th, 4th, and 1st rounds, same point of impact. Carbine has micro groove rifling.
