This is a 100 yard target with THE 265 FTX using a full length case. This can't be done in the marlin as the case must be one tenth of an inch shorter to allow it to feed.
Cases for the factory FTX load can't be reloaded using standard dies and require new dimension dies.
The 265 flat nose soft point can be loaded normally.
My load is over maximum for the marlin and should never be used in it.
