Anyone using Hybrid 100v or H4831 in a 6.5CM?

Like the title says...

It seems that H4350 is the mainstream powder of choice for the 6.5CM but it appears more velocity can be had with 100v or maybe H4831 or H4381SC and possibly do it with less pressure. Has anyone tried either of these powders? The 100v is about dead in the middle on the burn rate between h4350 and H4831 but from what I gather (even though no one has gave a straight answer) it probably is more temp sensitive then the "H" extreme powders. I am looking to run a fast load with some Berger hybrids to try and beat this dang Oklahoma wind as best as I can. Currently I am running 140VLDs over 43.8gr H4350 and it is probably a tad bit hot.

I made a post in the reload depot about my load with Hybrid 100v in my 6.5 creedmoor. I used 42.5gr with 140 gr Amax's and 140gr VLd's and was getting 2900 fps and 2860 fps respectively. This is faster than what the Hornady books tells me it should be but I did not see any signs of high pressure. I really liked it and will probably switch over to mainly using that after I do some more testing with it.

In a 21" barrel, 46 grains of H4831SC gives me 2670 fps. 47 grains is slightly compressed. Factory ammo in this rifle shot 2730. I think the 4831 is just a bit too slow. I don't have any H4350, but I'm going to get some soon.

Thanks for the reply. I was thinking the H4831 would be a little slow for the 6.5CM but wasnt for sure. I bought some 100V I am going to try out. I have had great luck with H4350 just wanting to try other stuff out there.
