Hello, new guy here. Been reloading for a while but just started my hand at 380. I know published data is always over and it all depends on gun etc... But it seems that my velocities are low for what I'm doing. If you are using similar components of mine I'd like to know what you're getting and possibly what I'm doing wrong, or is it acceptable.
So,
Everglades 100 grain flat point plated
3.8 grains cfe pistol
Winchester primer
.940 depth
Light taper crimp
With this I'm only getting around 750fps.
Is that normal or am I doing something wrong. I know the depth seems far but with the flat point the suggested min depth of bullet was barely in the case. I found a formula for depth online stating cast length+bullet length - .175. I tried that but still only 750. All cases look good, no bulging, primer flattening or blowout. So it seems pressure is good. But max grains is 4.0 for cfe and I don't really want to go higher and I don't think .2 grains will make a huge jump.
So, what should I try? Try a liitle deeper with bullet, liitle more crimp, or just be happy with it. Only reason I'm asking is most places get mid 900 fps. I'm not aiming for that, it just seems 150-200 fps off is a little much.
Thanks.
Forgot to add, this is out of a Bersa Thunder with a 3.5" barrel.
