308 load not burning all of the powder?

[TUK101]

I shot about 25 165gr Core Lokt bullets with 44 gr. of Varget and CCI 200 LR primers today. The temperature was around 32F with a bit of show in the air. Now the rounds shot well, and grouped descent, but every time that I would extract a shell, some powder that wasnt completely burned would fall out of the brass. Could it be that that particular load could use a magnum primer in that cold of weather? I have never seen Varget do that before and I have shot the stuff in colder weather than this. What do you think?

I wouldn't go fooling around with mag primers for safety.My best guess is some lube in the case is causing the problem.

ITs very common and happens more times than most people realize. Back off half a grain. This is one of many reasons that more powder does not always mean more speed.

The part about "shot well and grouped decent" should be your first concern.

how long is your barrel?
did you chrony them?
I've saw this before shooting IMR 4350 in a 12.75" barreled contendor, probably the powder is just on the edge of being too slow for your cartridge and barrel length combo.

The rifle is a Mossberg mdl 800 with a 20+ inch barrel. I will back the next batch of shells off .5 gr. and see if that helps.

You have several areas of opportunityto look at I believe? First off I don't care for CCI anything(JMO) they are blow hards (literally) those that reload alot know what I'm saying, second Varget is slower burning powder like IMR 4350(NOT neccessary a bad thing, BUT if you go beyond the ultimate burn rate load) you will have left over, building more pressure than you knew possible,in certain barrel lengths, 3rd what was your OAL setting in what rifle? Some times the best BUDDY's load isn't what you need or WANT in your rifle? I could be off on these suggestions(for your situation), so please check and recheck everything I mentioned.
