[QUOTE="Hntbambi, post: 536277, member: 12797"] Commercial ammo manufacturers do often use propellants that are not available to you and me. I am not saying they don't use off the shelf powders, but they have a few more offerings than we get. They also have pressure testing equipment that the majority of average Joes do not. They have mechanical and chemical engineers that calculate and analyze data to see that Bubba does not blow his gun up when be buys their ammo. There are a lot of variables when crafting a load, component selection, chamber size, throat length and angle, bore diameter, barrel length, bullet bearing length, distance from bullet ogive to lands, etc., so telling someone it's ok to load starting at or near max would be negligent and reckless. Even though a load that is worked up in February and is perfectly safe not be safe in July. Test over a variety of temps and conditions (like the factories do) to be sure you have a safe and well performing load under most or all conditions. I would take a load that shoots 3/4 MOA all year over a load that shoots 3/8 MOA for 4 months. As you look at your loading data and results (using commercially recommended recipes), you will learn what to look for, when you can take short cuts, and how to develop a load quickly and safely without asking for pet loads, or if something is ok to do. Many of the same people you may be asking have similar knowledge or are only keyboard experts. [/QUOTE]
