Question all the “gunnies” out there; has anyone else encountered a problem with older Marlin 336 in 30/30-35 Remington or the 444 models with 444 Marlin with the new Hornaday Flex-Tip cartridges locking up, and the feeding correctly? I have a 444 in the shop right now, and another on the way in 35 Remington, MD336. The customers contacted Marlin, and they had a Washington DC answer about it. I’m suspecting a carrier issue, after noticing the “flex-tip is quite a bit longer than the standard Remington factory. Loads in 444; perhaps not deep enough to handle this just little longer cartridge. I haven’t the chance to examine the 35 Remington cartridge yet, waiting for customer to bring it in with the ammo. Would appreciate anyone input on this before I start breaking things down.
