Just a couple of websites to share with everyone. The first is Ballistics By the Inch. This one is interesting as they go through some of the most popular calibers and show results for each according to how long the barrel is on your gun. Helps to decide which round you may want to use in that short/long barreled gun you own. The second one is Ballistics 101 which shows all manufacturers data regarding each round. This one is nice as they include rifle rounds as well. I wasn't sure if any of this was posted before but I didn't find anything through the search feature. If shared before sorry for the repeat. If not then enjoy.
