Varget lot variation

[Shifty6br]

Fellas....switched out to a new 8lb lot of Varget as I finished the last....started out .4 under my previous load of 29.6 gr.

I am at a whopping 130 fps differance...same bullet (75 vld) same seating depth. same neck interference, same primer, everything the same but different lot # in powder.

Anyone ever seen a huge swing in difference like this...have shot a whole bunch of Varget in many calibers and have never seen such an extreme swing.

Bottom is my usual load...top was the 6 test rounds I made with new lot.

Maybe that's why they are selling 8.8s now. Little extra for your troubles of having to work up a new load.

Maybe it's a combination of things??? Like, certainly their can be a difference from one lot to another. But in addition, there could be a difference in moisture content. Do you happen to know the moisture content of the old powder just before it was use up?

Gentlemen,

I also had the same experience with Varget. But I had to increase my charge additional. .4 grain to maintain my node

Had the same experience with Varget in the late 90's early 2000s

It's around a year old or less.. ..tho it has sat factory sealed in a room om the main floor so it's kept dry and in a climate controlled area.

I've experienced lot variation with Varget but never this extreme....holy cow I'm not sure I can hit my upper node with this lot which is pretty frustrating.

Definitely needs more testing.

Aaahh...they can keep it for the troubles...

I've had many Varget swings over the years. I had a huge one like you mentioned with IMR 4064. But yes... Varget is all over the place when it comes to lot changes. Not surprised at all.

Ok thanks....this my first to see this huge of a swing but now I will join the club of "this sucks".

Prob safe to say I'll see this drop across other calibers...damm.

I've seen huge lot to lot variances with varget. I'm switching to VV when this 8 lbs is gone.

Which VV is a replacement for Varget?

That... AND Hodgdon prices are and absurd joke right now.

N140 or N150

I have used varget for years. I always mix new lot with old as 8 lb jug gets low. I never see the lot variations that others have complained of.

 

[Bronsin]

I changed to a new lot of LT-32 and it goes 100fps faster than the old lot. The thing is, the accurate powder nodes were the same as before, just faster.

N140 or N150

N140 is right next to Varget on the burn rate chart

Same. I manage my stored powder’s RH levels through the use of Boveda packets in the neck of the bottle and I’ve never had a problem with lot to lot consistency.

there could be a difference in moisture content.

It gets a bit faster as it dry's out a bit from my experience, the moisture content and humidity play a big part. Ive seen this with other powders as well.

I've never had more than 40-50 fps variation with different lots of Varget. A hundred fps is huge!
