Varget - Low Velocities?

[Justice1327]

This is what I use to store my mixed powders.After mixing various lots of powder I dont have drastic FPS changes. this essentially is a new lot number. The only downside is if there is a recall on a specific lot, you have to look at your logbook to see which powders the lot numbers were from.

I really don't use Varget that much so maybe 3-4 lbs on hand. I will look at lot numbers and post up. Right now, caught creeping crud from granddaughters this past week. Thought I beat it but instead kicking my butt today. So the usual OTC plus IV OJ.

Mix one pounders all the time, yet to open new 8 pound jug. I'm going to have to load out of it soon and check speed. If its crappy I'll consider sending it to Butter Bean! Joking Bean don't get excited!

Get some rest brother. The Daytona 500 on that should put you to sleep.

Well just saw start, full lap 1, so I am good for a while.

Hodgdon have NEVER made powder, they just package it and sell it.
Having worked at the ADI plant, I know that single pound and jugs are almost always from different lots, it's just how it is distributed.
If you smell a new lot of powder and it is heavy with ether smell, it is going to produce slower velocities.
Although lots are held to be within 3% of each other, the ether content, and how much has retained plays a big role in the final product with single based powders.
This doesn't happen with double base powders.

Cheers.

Why doesn't this happen with double based powders?

Double base powder has no ether as a plasticiser, the plasticiser is the nitroglycerine

Cheers.

I'm assuming that you've run this load over your chronograph on more than one day right?

Well the last 10 laps was fun to watch.

I've been thru the same...but with an 8# jug.
I have a slooow batch. My MV is 75-85fps down from my old load , and when I was trying a new load in a different caliber with this jug of Varget, I was 150fps slower than the book with max load....had to pull the ole IMR 4064 out to get back to speed!

I actually loaded up 3 to test as double check and were spot on the previous day velocity numbers. I still can't believe it.

Plus I shot s 300WM load with 196HH day before which was spot on to rule it out.

This is a good reminder of the possible lot to lot variations. Slower velocities in this range is perplexing, but if this was in the opposite direction, more serious issues could result. I have pushed the envelope on loads where velocities were lower than expected at book max. Changing lots always should be adjusted back to book levels.

My 8lbs jug from 15yrs ago is hotter than the conservative Hornady manual charges. I typically need 1.5gr less and get higher velocities. Or maybe powder gets hotter if it sits longer?

I've not personally seen that big a swing with Varget but I have with H4350, H1000 and Retumbo. Up to 5-6% on the wild side, usually 2 to maybe 3%. 3% of a 50 grain load in Varget is 1.5 grains, I don't have by log with me but I am guessing that is at least 150FPS in a 308 class cartridge? I run my main 308 fairly hard with Varget, upper 40's with a 168 making 2840 out of a 26" barrel so I will always load at least 5 and usually 10 with half below and half above current charge when I switch lots at .2 or .3 intervals. When the chrono reads 2840 again it stacks bullets again and all is well. I do the same with all powders I have a really dialed load for.
