CFE Pistol, 9mm, Stovepipe Jams

147 Grain Hollow Points, started at 4.5 Grains of CFE Pistol, moved up to the recommended max, 5.5 Grains, still getting stove pipes in 4 different handguns.

Old stand by powders do fine, just the CFE Pistol powder,
Doing it with CCI & Winchester primers.

Anyone else had this issue?
 
Since these rounds cause havoc with all those pistols, and reloads with other powders don't,
It's got to be some disagreement between the powder, bullets or some change in reloading associated with that combination of ingredients.
The obvious cure is not to use that combination.
See how easy life can be when we're not fighting Mother Nature.
 
I show 147gr with CFE Pistol maxed out at 4.2gr for 963 fps.

I don't use CFE Pistol so I am of little help other than suggesting going to Longshot or HS-6 or any slower burning powder. I have had better results with slower powder on heavier bullets and faster powder on light bullets.
 
Hs6 is a fantastic powder for nine. It works well with lighter bullets, I can't remember if it is optimal for heavier.
 
What bullet are you using ? and where did you get the data . Hodgdon only has Horndy 147gr xtp for there data . 3.7 min 4.2 max . Could it be you're hot rodding them and that's causing the issue . .

As for burn rate CFE pistol is kinda slow #44 on the chart . Titegroup #14 , W231 #30 , 800x #38 , HS-6 #42 .

I'd think CFE would work well in 9mm and 147gr bullet . Slow-ish powder , heavy for caliber bullet seems like the right combo .
 
Yeah those were likely hot when you started and are hot loads at tgis point. Which is likely the reason for your stovepipes.

Combine a hot load with a stiff enough spring and the slide will bounce back and close quicker. Your still getting a full stroke thanks to the recoil so it will grab the next round and feed it but the slide will close on the extracted casing.


Back off to 4.2gr or less and it should run fine.


Look at your primers and check for overpressure signs like flattening. Case may be bulging too at this point.
