Which cartridges work best with the below powders

IMT 8208XBR - .20P, .204R, .223, .308W

BENCHMARK - same as 8208XBR

HV100 HYBRID - no info

H322 -no info

Accurate 2495 - no info

TAC - same as 8208XBR

I use IMR 8208 for high temperature, like about 90 F, rodent shooting with 40 grain .204, VMax's in the .20P & .204R (both 11 twist) & 53 grain .224 VMax's in the .223 (9 twist).
 
My 6.5 CM loves Hybrid100v, it gives tight groups, but it also like rl17, h4350 & Varget. It's a good problem to have the Creedmoor likes alot of different powders but the Hybrid100v shines in my CREEDMOOR
Thanks, I will give it a go. What charge/brass you using?
 
I've tried the h100v in a 6.5 creedmore 140gr, 30-06 150gr and 300 win mag 200gr with bad results in all three. The ES in all three was terrible through my tests so I gave it away. The 6.5 vanguard had a es over 120fps.

H100 V was STaBall of today. It offered extra100 fps. Just wasn't the most consistent of powders. Though it shot really well in 6.6x55 of mine at the time.
