Never could get any accuracy out of the 90-95gr 9mm bullets. Ive used fast and slow powder. Ive also used light and heavy loads. But they never shot well for me.

How do you like that CFE powder?

 

[ColoradoShooter77]

My 95 grain load shot really damn good, printed a nice group on target at 30 yards off-hand.

As far as CFE-Pistol goes....I like it! As soon as I use up my Longshot with the 40 cal, I'm going to standardize on CFE-P for both 9mm and 40 cal.

Gorgeous day for shooting today! Thanks for the data. Loaded some CFE in 9, 40 and 45 as my buddy and I want to pair down the powders we have been using. Just trying to get a date to go shoot it and see if we like it.

 

[ColoradoShooter77]

From what I can tell, CFE-P like to be on the top end of the charge range. As the charge weight goes up, the extreme spread goes down.

 

[Slamfire]

Five round strings will give deceptive ES's and SD's. Try shooting the same ammunition lets say, 30 rounds. My Chrony only goes to a 32 round count, I wish it were 50. Fifty rounds makes the typical box of ammunition. But I have seen time and again, small data samples being unrepresentative of the larger lot.

 

[Walkalong]

That is true of course. I usually do small strings as well, but take the ES & SD with a grain of salt. Lower is good of course, but as Slamfire posted, it can be deceiving.

Little ragged groups are what make me smile. A low ES & SD for pistol is nice, but not the cure all/end all.

Of course if you shoot six shoots from your revolver and get a 45 ES, it's not looking good for the home team if you plan to shoot these at distance.

 

[ColoradoShooter77]

I will say that Longshot is no joke, it will easily push a 180 grain HP to 1100 fps...pretty stout. Recoil wasn't bad at all.

ColoradoShooter77, thanks for sharing your chrono data.

9mm 124 grain Berry's, 5.3 grains CFE-Pistol seated at 1.135"

Which of the 124gr Berry's bullets did you use?

At what altitude did you test these bullets?

 

[ColoradoShooter77]

Its the Berry's round nose and I was shooting at 9000 feet. I goofed on the seating depth, its actually 1.150".

 

[RPegram]

The IMR 8208 looks very impressive! How was accuracy? Just did a little quick research and it looks very temperature stable. Also, does it meter well? I might just have to pick up a pound or two and give it a try.

 

[ColoradoShooter77]

I shot the AR off-hand from 50 yards, so it wasn't a good accuracy test, but it printed a nice cluster.

I don't use a progressive loader, but the kernals are small, much smaller than Varget, so it should meter pretty good.
