[QUOTE="Stammster, post: 2435047, member: 114381"] 7828SSC has a slightly slower burn rate than H4831SC. If memory serves me correctly, max will be about 62gr for 130gr cup and core bullets. However, the Hodgdon lists a compressed load of 60.2 gr as max for the 130 TSX at just shy 3100 fps at 62 kpsi. The 270 is good for 65 kpsi. Start off low and work up. I’d personally start at 57 gr and shoot a one shot Satterlee ladder for velocity and POI in 0.5 gr increments. Based on the results, focus in on what works best. Your probably going to fall into the category of “you can’t fit enough powder in the case to get in trouble”. Review this thread also... [URL unfurl="true"]https://www.longrangehunting.com/threads/imr-7828.260738/[/URL] If you can’t get the TTSX to shoot, I’ll trade you some 150 gr Partitions, 145 gr ELD-X, or 150 gr Fusions. One of those will work with your IMR-7828SSC. But the 130 TTSX is a great choice for Elk. [/QUOTE]
