    Did the Model 70 lightweight rifles ever have a documented problem with the safety and misfires? Somewhere in the back of my mind I recall a problem when the gun was put on or taken off safety? I dont ever remember Winchester acknowledging one or having a recall.

    Yes but.....375 brass is heavier/stronger for the stouter load.

    38-55 can be fired in a 375 but not reversed

    DO NOT, and I will repeat that, DO NOT, load 375 loads into a 38-55 case. The 38-55 case is not as strong as the 375, plus there is the possibility of it ending up in a 38-55 chamber.

    That is part of the reason they came up with the 375, is the brass, down by the web is thicker, and stronger. They should have made it longer than the 38-55, so it would not chamber in that rifle.

    fordsix,

    I am not sure where you are getting that from, but the 38-55 case length, is 0.065" longer than the 375 Winchester. At best, you are craming the case mouth into the chamber throat...not good.

    The .38-55 has a longer case than the .375 (hence the OP). It MAY be possible to chamber a .38-55 cartridge in a .375 and then shoot it. Since the .38-55 is such a low pressure cartridge, there would probably be no repercussions. Having said that: I wouldn't do it! I always thought that it was a mistake on Winchester's part to create a cartridge loaded to a higher pressure that is so similiar to an older cartridge that it would be tempting (almost irresistable) to try to substitute one for the other. There are a bunch of us that think of cartridges in terms of .22 S-L-LR.

    EDIT: I don't think Winchester could have made the .375 much longer than the .38-55 and still have it work in the Model 94. They probably should have gone to .40 caliber. (Think .405 short!!??)

    Fellows,

    There is another consideration that must be taken into account. Specifically, the bullet diameter is different for the 38-55 and the 375 Winchester. For the 38-55, the proper (nominal) bullet diameter is .379. The 375 Winchester is .375. Shooting an original 38-55 cartridge in a 375 chamber (if it will fit), will drastically increase the chamber pressure[B)]

    375Win data, used in a 38-55 TC Contender. They were able to have the scope repaired, after one of the base mount screws went through one side of the scope tube.

    You need to look at the older reloading data books. Both of my 38-55 rifle barrels slug at .3795, and I use .380 diameter bullets. Stuffing a .380 bullet down the bore of a rifle chambered for the 375 Winchester cartridge is asking for bad things to happen[B)]
