Has anyone worked up a load with Hybrid 100 V? I am trying it out in my Remington 260 starting out with 39.5gr and a Barnes LRXBT 127gr also have some H4350 loaded up.
H4350 will be hard to beat; it's what I run in my 260. IMR 4451 is also worth a look, very similar to the H4350 but I have seen a little more temp sensitivity with it.
I'd be interested how the 100V works for you since H4350 is hard to find at times.
