Loading for the BAR

How does one know if a powder is suitable for loading in auto-loaders, specifically the Browning BAR? I have read that auto-loaders need powders that will have a certain "pressure curve" suitable for auto-loaders.

I have a BAR in 300WSM and I would like to know if the powders I am using are OK. All of the information I have found pertaining to pressure curve and proper burn rate for semi-autos is for the 30-06 and 308. The powders I am using are R-19, Hunter, MagPro and I am about to try N560.

Thanks
Steve

    What you refer to is the M1 Garand. It was designed to opperate at certain port pressures. If the pressures were too high as when using slow powders the operating rod would bend. It is a long thin rod.

    The modern BAR is designed to shoot modern ammo loaded to the pressures the rounds are designed to run at. My BAR in .338 win mag seemed to like the loads on the hot side for best accuracy. I used about every powder available for the .338. I settled on RE19 and 225 Hornaday bullets for best accuracy.

    Same here, I have two BAR's, one 270 Weatherby Mag, one 338 Win. Mag, I've loaded both with probably 8 different types of powders as listed in various manuals, miniumum loads to max loads, have never had one problem with any of them.
