Accurate No. 5 Chronographed

[9mmMike]

I had the chance to use a chronograph for a nice shooting load in 9x19 that is very accurate. The temperature outside was 51 degrees and the barrel I was shooting measures 3.5" in length. I set up the chrony 10 feet away from muzzle to the first sensor.

Powder Accurate No. 5

Charge 6.2 grains

Case Winchester 9x19

Bullet Hornady 124 gr XTP HP

Primer CCI-500

COAL 1.075"

No Crimp

Five shot group

1034 FPS

1035 FPS

1035 FPS

1031 FPS

1036 FPS

All shots touched each other with 2 going through the same hole. Brass cases just laid down about 3 feet to my right. Recoil was modest and muzzle report was quiet. I was satisfied with this load. I also used Winchester small primers but velocity dropped 20 fps and bumping charge weight .2 grains brought it back up but accuracy started to wane. I really wanted to get 1100 fps out of the 3.5" barrel but I just couldn't get the load there without going too overpressure and losing accuracy to powders that can get there a lot easier.

For sh*ts I chronoed' Winchester white box 9mm 115 grain fmj and was consistently getting around 1030 fps out of the same 3.5" barrel. It was very accurate as well.

At what distance?

[Hi-Power Jack]

The velocities are remarkably similar:)

I've done that a few times, with the first

five rounds being all the same, but by the

time I shot an additional 15 rounds thru the

chrono, I get some more dispersion.

Same with a 5 shot group - every once in a

while I get a remarkable 5-shot group (I

have some hanging on my wall over the past

25 years), but when I fire a 12 - 18 round

group, I usually get more dispersion.

Sounds like you have a great load there for

your gun - but you might want to run some

more rounds thru the chrono and the target

to see the true picture.

Good luck,

Jack

The target was 15 feet away. I'm sure I could get more deviation if I tried. I shot 15 rounds and was under 10 fps on all. I will do some more and see what happens.

The target was 15 feet away.

I shot 15 rounds and was under 10 fps on all.

Mike, I'd move that target back to at least 45 feet and see

how a dozen rounds group. 60 - 80 feet is even better:)

That is great deviation on 15 rounds - all new brass?

New brass. I shot 5 again with pretty much same results. Great target load. I would have done more but I just discovered hs6.
