[QUOTE="yorke-1, post: 1524651, member: 11960"] I prefer first hand experience to computer models, but Quickload won't help the fast powder argument. These were all done using factory presets in Quickload with the exception of the internal case capacity which I adjusted to match my once fired Winchester brand 300 Win mag brass. I chose to use 3.600" for the OAL since that will likely be more representative of the gun being built than using the SAAMI spec 3.400". All loads were adjusted to be as close as possible to the max pressure spec of 64K psi. H1000 was used for the slow powder and H4350 was used as the fast powder. I chose two Hodgdon powders in order to limit differences caused by drastically different powder compositions. Barrel lengths used are 26" and 20". 26" barrel results [IMG]https://i.imgur.com/FkHJ5w3.jpg?1[/IMG] [IMG]https://i.imgur.com/hzlAz1r.jpg?1[/IMG] 20" barrel results [IMG]https://i.imgur.com/vv8XIjQ.jpg?1[/IMG] [IMG]https://i.imgur.com/Ei9qPCB.jpg?1[/IMG] I'll admit, H1000 is only getting a 99.8% burn in the 20" barrel in this model. I don't know that I'd really call that significant though. Then again I don't drive a Prius and worry about fuel economy; I'm more interested in performance. [/QUOTE]
