Anyone use cfe pistol for 45 colt? 185 grain bullets. Getting a little bit of black down the outside of the brass and have little light brown baits of powder? Never ran into it before

I've found CFE Pistol to be a very dirty powder unless at max loads for 9mm, .38, and .45 acp. Anyway, my Sierra app has load data for 185gr JHP (OAL 1.522) and FPJ(OAL 1.460) projectiles of 10.0gr min to 11.5gr max. It doesn't list what the test gun was or the barrel length, so as always, be safe.

Got another one. Can't seem to find a good answer. Any good way to know if you've pushed too much pressure in 44 magnum?
Brass from lighter loads looks about the same as heavier loads do

180 gr XTP
30.5 gr H110

 

[Jester896]

that might be a tad hawt

what does 30.5 hr H110 mean?

 

[Jevaughn]

Yeah, when the primer flattens out and fills the pocket, that's usually a sign of high pressure. Might be within normal powder limits by the book, but your cases might have less capacity than the test cases, or maybe to much crimp.

Grains. Typo

I have been reading around, most of everything I've found says you can't only rely on primers flattening. My lighter loads fo the same. Should have added that. Was just wondering if there really was any good way of knowing

 

[Jhunter]

Buy a chronograph or Labradar. Velocity is the best data. Start low and keep adding while tracking velocity. You will find pressure as velocity starts to plane. Don’t rely on others data

 

[Jester896]

did you use the LP or a LPM primer?

 

[RobertTaylor]

Large pistol. That's what it called for

Might just be a soft cup material then. I've had Winchester spp do that in some 9mm and 38 loads I was running hot, 357 mag loads will damn sure do that. Most pistol powders don't require Magnum primers for full ignition, but some need it just for the added thickness of the cup. Try the same load with a harder/thicker primer and see if you get the same result.

Thanks. Wasn't sure where to go from here. Only have some old Tula primers I've been using

Chrono is a great way to get an idea. It is *possible* to have too much pressure and still only be running standard velocities, but it's unusual. As an example there's a powder that lists a max load in .40 at only 900 fps with a 180 grain bullet. Even at max OAL it lists the pressure right at the limit. There are factory self-defense loads I was regularly getting 980-1010 fps with in the same bullet weight.

Like others have said, the primer flattening out isn't the best metric, but if the primer dent starts to flatten out as well I might pay more attention!

 

[Jester896]

i see where it is sucked into a cavity of some sorts around the firing pin hole. Primers can be a good sign you are on your way to an issue.
I am working on a .243 load with Barnes 80gr TTSX. I loaded 5 rounds each from a gr below the middle to the middle in .5gr increases. I didn't need to shoot the last 5. The primers were starting to suck into the firing pine hole.

FWIW I can't find a load in Hornady 11th for a 180gr bullet with H110. The max for the 200gr XTP is 28.7. Also can't find one in Nosler. Their 200gr performed best on 27.5gr of H110.

Yeah, they don't have it. I just happened to only have 180 grain bullets at the time. Checked around and Hodgdon had data for them.
I bought too much h110, first time I've used it. Read a lot about how fast it supposedly erodes tops straps and forcing cones. May start looking to trade off a pound for something a little better suited for shooting a lot of

 

[Jester896]

or move to a heavier bullet....I use it with 200 and 240s. Works real well with 240s in my rifle and pistol and they are loaded in the middle for Nosler Data for their bullets

Can anyone ID this headstamp?
