[QUOTE="Gunpoor, post: 376666, member: 8358"] I would answer your question if only I can find what I did with that crystal ball. Oh well, in the mean time you could just shoot them over a chronograph and see what that tells you. In theory a longer COAL should reduce chamber pressure and therefore reduce velocity, that is unless you encroach the barrel lands which will then negate that theory by increasing chamber pressure. Why don't you shoot your loads and post the results and then let everyone dog pile you with responses? In large capacity cartridges the slow burning powders such as your Retumbo are nice because you will hardly be able to stuff enough propellent in them to cause dangerous pressure situations, but you need to work up slowly to find the sweet spot for accuracy. Good luck with you load developement! [/QUOTE]
