6MM BR and Varget Powder Charge ?

[foxguy]

I have been loading 6MM BR and 105 gr bullets with 30 gr's of powder. getting appx 2880 fps, great Groups .350 @100 yard. The Varget powder I've been using is coming out of a 8 lb jug which I'm on my last 1/2 lb. I've ordered 2 lb's of Varget (as 8 lbs aren't currently available). The question to you experienced 6MM BR loaders. If 30 gr's of the new lot of Varget doesn't give me the same velocity / accuracy, have you found that just adding / subtracting a few tenth's of a grain to get your velocity back to the old lot of Varget, will it typically produce the same Accuracy in group size?

Thanks for sharing your experience knowledge on this.

It should be close but when in doubt I would run an abbreviated ladder test to ensure or recapture the same node.

^This. Just be wary of the lot to lot differences.

Agree with this. Don't hurt to just take a quick look at it and see where it actually is.

Keep looking, it’s out there in 8 lb containers. I bought one from a local shop not long ago…

I have a Chronograph so when I test loads for accuracy I will also be capturing the load velocity for comparison. I suspect that I should have the new Varget powder by Dec 2nd or so.
