For a 6.5x47L with 130g-140g Bullets?
Varget is a good all around powder, and I've found it very tolerant with a wide range of weathers and temperatures.
varget or H4350!
Varget, H4350, IMR8208XBR, AR COMP.
I settled on Varget for my 6.5x47 with 140s.
Good old Aussie made Varget (AR2208) or H4350 (AR2209).
Varget... I tryed vv550 with the 140 amax (shot real well) 6.5x47L but at 36.00 a lb and a rat race just trying to find it...~Danny
GOOD I do have 2lbs of N550 when mine get done!!!
N550 is a good powder for getting high velocities, but is known to be more temperature sensitive than the single base powders mentioned previously.
+1 for Varget. Very insensitive to temp change. ;D Paul.
I agree with the consensus on Varget, with a second choice of H-4350.
Anybody tested the temp sensitivity of the Ramshot line???
I don't have a 6.5x47L but IMR8208XBR is by far the least temperature sensitive powder in the 308 winchester weve tested. Single digit extreme velocity spreads & velocity change regardless of temperature.
which is not surprising as H4350 is the slower brother of Varget, ie Aussie made AR 2209 v AR 2208
I would say a bit too fast for 6.5x47L but finally after being available in the USA for quite some time ADI have finally released it in Australia under the new name of Benchmark 8208. Looking good for a play with the smaller calibres with this like .204R, .222R & .223R but it may be interesting in .22BR, as with most of the ADI Powders... Single based, temperature stable.
IMR8208XBR in my rifle with 35.1g gets me 2788 fps with a SD of 4.6 and 0.5-0.6 MOA. Too fast, not sure.
IMR 8208xbr is too fast of a burn rate for a .243 Win. but it works great in my little coyote/ rock chuck gun with 55 gr. bullets and consistent from Damn cold Wyoming weather to todays highs of around 105!!!!!!
varget in my 6.5x47 only
Varget, do not try MagPro, it is very temp. sensitive.
Varget or 2208 is awesome with 130gr bergers.
