[QUOTE="azsugarbear, post: 1112691, member: 4809"] The OP also asked what we do to find our best load. The max loads that are often listed in a reloading manual for different powders may or may not be the max load for his particular rifle. Even the manuals from all the major bullet makers don't agree on what a max load is using the same powder. Each rifle tolerates pressure differently. If you want to find out what the max load for your rifle is with a specific powder/bullet combination - I only know of one way to find out. Start below max and work up until you start seeing pressure signs. I then back off one whole grain - and that becomes the max load for that rifle with that powder. Anytime a respected company publishes a 'max' anything, they are opening themselves up to liability claims if they cannot back up their data. Whether it is tensile strength of steel in a building, max load of an airplane wing or max powder charge in a piece of brass- it becomes a line in the sand that company may have to defend in court. Therefore, they often use the lowest common denominator when coming up with their 'max' recommendation. Judges and juries find it difficult to hold companies liable when they can demonstrate their 'max' was ultra conservative, but are much less forgiving when they find a company either pushing or right at the envelope. I always keep an eye on the published max, but I rely on the data my rifle is giving me more than an conservative average in a published book. I believe in being safe. But I also want to wring max performance out of my caliber & rifle. You can't do that by simply relying on a book designed with the principal "one size fits all". [/QUOTE]
