With that H100V 130ABs and the 140 Partitions put three in half inch moa at 100yds. Did a phone book test and WOW! Them 140 NPs really kicked butt. I didn't really wanta run the 140's I was actually hoping to go with the 130's or 125NPs. But, if your killing phone books the 140NP outa the 260 is one bad MF'er! Seriously has left little doubt about the 260 and 140 NP's for elk..
I'm not sure about the temp sensitivity of this powder yet. Thats why I'm interested in H4350.
Recent Handloader had an interesting write up on a new powder. IMR-8208 XBR.. Looking forward to getting my hands on some. No temp issues and extremely accurate.
What weight SKG's are you running?? Can ya share that info?
Ever use any IMR-7828 SSC?
