I used to use 2206h on my 7mm08 ive since gone to 284. But I was shooting shitty speer 145 grs at around 2750 - 2800 fps. My tikka t3 was cut down to about 18 inches. I think I could have got more out of it if I stuck with it and changed the peojectiles. Excuse the estimates I'm not home atm so can't give you exact info.
