Could anyone run these through quickload, and get some estimates on pressure? I don't want to get in an unsafe situation, never went over a book's (or knowledgable online source's) max. But, since I don't have a chronograph, maybe I am not taking near advantage of what my 6mm AI can do. Would 46 grains of RL 19 be too high to start with a 105 grain bullet?
If you don't have a chronograph, it's wasted time to have someone run QL for you. The powder charge is meaningless without knowing the velocity. So many reloaders get bogged down in the "max listed powder charge". Velocity tells you your pressure, not any number on paper. Is 3400fps reasonable in a 6mmAI with a 100gr bullets and R-19? If it is, then you load up to that, and when you get there, you stop regardless of the number of grains. Again though, without a chronograph, you're wasting your time worrying about the number of grains of powder.
