Is 2/10ths under minimun load data dangerous?

Recommended Posts

Forgetting to measure my powder charge before getting started, I loaded up a couple of hundred rounds of 9 mm with 147 grain bullets and N 320 that are 2/10th under the minimum charge recommended.  I've always read not to shoot low charges but is this enough to worry about or would anyone use them?

I would definitely shoot them. Obviously watch for squibs within the first few rounds but they should be fine. You may experience some functioning issues depending on the firearm.

I'm not sure what minimum load is for N320, but I load 2.7gn under a 145gn IbeJiHeads bullet in my PCC. It makes 132 PF with no issues.

What are you looking at 2.9 to 3.0 gr of powder?  Shoot those things.  Should be fine.

You’ll be fine. Enjoy.

 

Worst case the gun is a little dirtier... with a powder that clean you’ll have no problems. ;)

I would bet pretty much, bet anybody that loads 147's  that close to the minimum without weighing every single one, shoots a lot of rounds that's 2/10 under minimum. Just saying.

You need a better powder measure.  My Dillon measures don't vary that much EVER.

I use Dillon been using it for near 40 years. Maybe you need a better scale.

Well I suppose you are right, but no powder measure throws exactly the same amount every time even from the factory. That is why powder tricklers was invented. And two tenths of a grain may not matter in the pistol. It can make a big difference in a rifle.IMHO.

2/10th when using TiteBoom is a LOT.

 

However I don't use that powder.

 

I use Clays for 45 ACP and WST for 9mm.  My drops don't vary .1 gr.  Boringly consistant.

+.1 to -.1 = 2/10ths
