Here is my question. Will I have any trouble with using a .060 vegetable fiber cardboard wad from Buffalo Arms in my reduced load 45-70 smokeless, loading of 13 grains of Unique under a 405 coated bullet? The cardboard sits closely atop the powder and its a nice close fit for diameter of the wad. This of course leaves an airspace between the wad and the bullet. The powder is right up against the primer with no air in the powder location. Will this cause any pressure concerns?
