I'd have to say the same thing about 43gr to 44gr of IMR4064 as well. 43.5gr is the ticket in my CTR, ~2,600 fps out of a 20" barrel isn't too bad for a easy shooting load.
4064 or 4198 if varget dont perform in 308. Need advice ASAP

"...Is there even a difference?..." Yep. Slight one, but IMR and H powders are different. Bullet weight matters though.
Only light bullet IMR4198 loads on Hodgdon's site. In any case, you'll find IMR4064 gives more consistent accuracy than either 4895.

Reduce your powder charge by 0.3 (three tenths) of a grain if using the "H" version.

My .308 WIN rifles love IMR 4895, and IMR 3031. Good luck.
I have had great luck with IMR 4064 and IMR 3031 in 308, Very Accurate. I recently shot a 5 round group, 2oo yards, IMR 4064, Hornady ELD-X 200gr. I could cover all 5 with a Quarter. And I believe the Deviation was 14fps, I don't remember the velocity, but it was just over 2700.

The results I was getting from varget was decent accuracy I can get half inch groups but The Sweet Spot isn't very big, and it is on the lower side of the min/max scale kind of want to be a faster sweet spot for possible long rang shooting in the future. I've heard of people getting terrible results with Varget and having good results with either of the other two powders that I mentioned so I figured I would give them a try. I ended up buying IMR 4064 going to load it up and try it out this week.
BTW I have a manual and it dont say anything about what other shooters experience with certain powders and bullets lol and I guess I could have specified that I want to try it in all weights

dgod, what was your charge weight and bbl length? I'm going to load up some 200gr ELD-X with 2000MR and CFE 223 to see if can get above 2500 ft/s out of my 20". Hodgdon says that a max load of CFE223 should produce 2582 ft/s under a 200gr Swift.
