The load seems pretty warm.

Does it seem like the cartridge is not being fed from the magazine quick enough for the slide to catch it?

Or, is it not feeding up the ramp and getting hung in the chamber?

What is your load data?

I’m a big fan of Silhouette when chasing velocity.

Just shooting them, last weekend was on a 5″ steel diamond at 545 yards. The wind was interesting but the bullets performed.

Fatboy-

What kind of issues are you having? Accuracy? Function?

If you are not having success with 8208XBR or Varget, then you need to look at other variables.

Check your powder drops to be sure that they are consistent. 8208 flows really well for me.

Sort brass by headstamp. Do you put a crimp on your finished round? I find that a light crimp really helps with a semi auto.

I might be turning my load down a touch to 23.0 SMP735. The 23.5 shoots fine in my AR and match gun but primers are starting to crater and show signs of flatness in the Remington.

I need to run some chrono tests to see how consistent the velocity is.

Maybe your gun just doesn’t like the MPR as much.

I’ve had a similar issue with my old 9mm Springfield 1911. It doesn’t like 147 grain bullets.

[SC]

4.1 grains is what I run. It is a pretty popular load with action shooters…USPSA, etc.

WST is really fast. I would try the N320.

[SC]

Do you have a faster powder to try?

A rumor that I read is that Federal uses Power Pistol in the 9mm HST loads.

I really like WSF and Vit N320 in 9mm 124 loads.

I have no experience with CFE pistol. It looks a little on the slower side than what I like for target use. Did it look like you were getting a complete burn or is your brass a little sooty?

What did the primers look like? Starting to flatten?

You may need to increase the charge a little more to get consistency.

[SC]

I have tried it in the past using Wolf branded primers. They all fired out of an H&K P30 but I wouldn’t be surprised if you saw issues with striker fired pistols.

There have been a couple articles on primer thickness. Here is a pic that I found online that compares them-
