Shot some Hornady 200gr HAP today

Hi
Glock 20-SF factory barrel and spring
I did a little preliminary shooting with some Hornady 200gr HAP bullets. First time shooting any 200gr bullets.

10mm Reloading Forum



Well, first off I found out 10.0grs of Blue Dot is too hot for this gun.. I Got smileys on all but one case. 9.7grs is about max here..

10mm Reloading Forum



8.2grs LONGSHOT was a bit too hot as well.. I got smileys on three of five cases.

800-X did pretty well. I could take it up one notch. Case measurements were fairly consistent.

2400 was kinda weird as pressures were all over the place but, gotta say it was pretty accurate. But if velocity is a factor, 2400 is not so good.
This is the very first time I had a split in a new Starline case..

10mm Reloading Forum


I also got a split case with 13.0grs of AA#9. So thatís two today. Is there something about 200gr bullets that causes this?

Iíve heard on more than one occasion that VIHTAVUORI loading data is a little off.. Gotta agree.
Pretty disappointing velocities. But, according to the case head measurements, I could take this up a notch or two.

But the winner today has to be 13.5grs AA#9..
Good velocity, good accuracy, acceptable and consistent pressure.

Case head measurements;

BLUE DOT
9.4grs .4341, .4334,.4341, .4343, .4335
9.7grs .4343,.4340, .4339, .4344, .4342
10.0grs .4340,smiley, smiley, smiley, smiley

LONGSHOT
8.2grs .4340,smiley, smiley, smiley, smiley

800-X
8.7grs .4335,.4338, .4339, .4335, .4333
9.0grs .4335,.4339, .4341, .4337, .4339

2400
11.5grs .4343(splitcase)??, .4336, .4339, .4330, .4330
12.0grs ,4343(smiley)?, .4338, .4337,.4338, .4331

AA#9
13.0grs .4340(split)??, .4339, .4340,.4338, .4339
13.5grs .4346,.4342, .4339, .4340, .4334

N-105
9.2grs .4330,.4328, .4335, .4336, .4332
9.5grs .4340,.4332, .4332, .4339, .4337

Well, thatís it Ďtil next time..

When they start making a 200gr hap? I have a case of the 180s. Would trade for the 200s.

Did you have any issues with the AA#9 pushing the bullet back out? What depth did you seat at?


I'd like to test HAP to see if it can expand. I know it's not designed to but I'd still like to try. I can trade you 200 gr XTPs for 200 gr HAPs, if you want. I only need a few. PM me if you're interested.

1.26".. I was upset at myself as I made a mental note, ha ha, to check this before I shot them.. But I only felt the bullet contact the powder at the very last while seating.
So, if they did move, it wasn't very much. No problems feeding.

PM sent..

It would be interesting regarding these split cases if you had same samples using a more supported aftermarket barrel, like a KKM or a StormLake.

My interest being that I ran 9.3gr LongShot on a 180gr, using hot primer CCI 350 and had no problem. KKM 6" barrel. Got 1350fps.

So it's hard to me to imagine that you ran a bit more than a grain less, 8.2gr, on a 200gr bullet and got split cases. That makes me reluctant to try the same 180gr reload using a stock barrel...

RDub01, you may want to investigate the use of atleast a extra power recoil spring for your factory barrel, this may help your brass situation and improve your groups.

Hi
I ran up to 9.5grs Longshot using 180gr Speer TMJs. I got a smiley at 9.5 but not the others. 9.2grs was warm but not bad.

10mm Reloading Forum



I should have worked up to 8.2grs.. I'll re-shoot this.. I'll find that 7.9-8.0grs will be max in this gun.

Hey Shadow..

I have an ISMI 22# spring and I have shot quite a bit comparing between factory and this one.

I found that in most instances I got better groups with the stock spring, and almost always got more velocity with the stock spring. Maybe this particular spring isn't the one I need.

Before I move on to a KKM or other barrel I wanted to get a solid baseline as to what the factory gun can do.

Check these out if you would like.. (the pics might be hard to see details..)

I would really like to know if the results I'm getting with this pistol are typical..

With a large aiming point like the target above, you'd be hard pressed to claim one load was significantly better than another.

I have tested my 180 hap for expansion. They expand close to an xtp. Just not as uniform. The hap is the same as the xtp. It's just missing the cuts in the jacket. Without the cuts the jacket just tears. That is why the expansion is not as clean. One could ads the relief cuts themselves easy enough.

Thanks Yondering, but this is where I'm at with this..

Here is a standard 25 yard pistol target, the one used by the entire world for training, competition and everything else;


10mm Reloading Forum


The black circle is 5Ĺ" in diameter.

This is the standard sight pictures that are taught to handgun shooters all over the world;


10mm Reloading Forum



I am using the 6 o'clock hold on the left..

The circles that I make on the target, from a template that I made are, are 5Ĺ" in diameter. This matches up with the standard pistol target.

With the Glock pistol, the 6 o'clock hold on the left is exactly what I see, as the front sight on the Glock is the same size as the round target at 25 yards, just like the picture shows.

It is actually much easier for me, from all the years of training I've had, to detect lateral movement if the front sight and the target are the same size, which in this case they are.

Regardless of what mechanics one chooses to use to establish a sight picture, if the gun is as still as humanly possible when the trigger is pulled, then that is all that can humanly be done. Human error is always present in some degree in this process. And some days are better than others.
And of course there is all the mechanics involved in shooting an autoloading pistol such as this. I'm working on it.

So, this is what works for me.
Thank you though..

I alway use the middle sight picture...A crosshair on the target can help you find leve! and vertical for finer detail. "aim small - miss small"
