I'm thinking about having a Marlin 336 rebarrelled to 400 GNR.

How well-matched is the 400 GNR with a lever gun? In practice, is the straight-wall a problem in cycling? Do the commonly available JSP/JHP 10mm/40 bullets hold up at rifle velocities?

How about forming brass? Best to start with 30-30? 38-55? 375 Win?

    - I think Alcorn is talking about the 355 GNR as - Gary Reeder, 2021-10-15, 12:25
      - Yes 355 GNR (nm) - Alcorn, 2021-10-16, 03:14
    - Will that work on a .35 Rem. rechamber? - WB, 2021-10-15, 08:35
      - it won't clean up the 35 Rem. chamber - Gary Reeder, 2021-10-15, 13:09
      - WB I’ve had at least 20 Marlin’s - Sid R, 2021-10-15, 10:03
        I’ve only had (3) .35 336’s. Factory ammo was fine - WB, 2021-10-15, 17:04
        WB yeah those parts look cheap - Sid R, 2021-10-16, 12:00
        Same exact ejector on a Win. M1912. A Mossberg 500 - Just saying, 2021-10-16, 08:21
