[QUOTE="royinidaho, post: 1038202, member: 2011"] Ball powder is the only type of powder I can shoot in my 270 Allen Mag with 165 class and larger offerings. US-869 is the only powder that produces the velocity in this rig that maintains it's extreme magnum status. Other [U]available[/U] ball powders can't match the 869's velocity. Having said the above US-869 flat sux!!!! Es never under 30 except every once in a while.:rolleyes: Lot to lot variations will drive a fella nuts. Who wants to burn barrel life every time powder lot is changed. My solution to the lot to lot problem is maintaining the powder level in the 8# canister at the same level by adding a pound can or two from time to time. Shake that sucker well and variations seem to smooth out. Temperature sensitive? Did someone say temperature sensitive? Hell yes it's temperature sensitive. Certainly at extreme magnum pressures. After shooting out one barrel, 900 rounds, and 200 rounds through the second barrel the sun, moon, stars, planets and the wife's cycles have aligned and with Matrix 165s all problems except temperature sensitivity [I]seem[/I] to have gone away. We'll see. This rig is relegated to use when temperatures are what ever they are between the first or so of October and end of April simply to keep from coming up with seasonal loads which is way too difficult for this ol' fella to want to keep track of. I'm hoping some of these new powders with have the SSC kernel size as with 150 and below class bullets 7828ssc works exceptionally well in all departments. [/QUOTE]
