Cordite is one of a few specific NC + NG + additive formulations extruded into strands. First generation Cordite had more NG than NC and was very erosive in spite of the petroleum jelly (Vaseline type) added. Second generation reversed the proportions to (small) majority NG. There are others. The strands could be loaded as such or chopped for use in revolver cartridges.
Modern cannon powder is extruded but cut into granules and depending on the spec, can be single base NC, double base NC + NG, or triple base NC + NG + Nitroguanidine.
Not sure what you consider modern but the powder bags for the 8 inch howitzer did not contain granules. they were tubes. this was ftom the early 80's to the early 90's. I imagine changing the powder would require intensive testing and rewriting the TFT's, reproducing the GFT's and rewriting the fire direction software. I shot powder bags that were produced during ww1. the bags were fragile. we literally duct taped the bags because they were falling apart. little tubes fell out. Couldn't hit anything with them. Constant corrections. Registration and met data was useless.
the modern 155 guns may have new powders. IDK.
