I bought a tc pro hunter with the 7 mm 08 barrel . Finally got to sight it in due to the weather, right now I'm shooting 120 Noslers over 43ish grains of IMR 4064 5 shot average at 100 yards is 3/4 inch. Which is superb in my opinion. I'd like to try to get a little more velocity though . 5 shot average over the chronograph is 2870 right now. I'm looking at trying varget or rl 15 . Which do you guys that's used these powders is more consistent and cleaner burning ? Thanks in advance
