Thoughts on a load for this unique 9mm bullet.

[Palladan44]

Ok, here we go:
9mm- 135gr Hydra Shok- DEEP JHP.
4.8gr. BE-86
OAL- 1.118" plus or minus .002
CCI- SPP
FC once fired brass
Glock 19 gen4 Standard
1008fps
1010fps
1020fps
1002fps
998fps
1019fps.

Right at the end of the string I Fired one more factory load through the chrono. just to compare felt recoil, and I could barely feel maybe a slight bit more recoil with the factory round, which produced 1036fps.....(But the recoil may have just been a predisposed assumption, in reality if I randomly mixed the factory round in with my loads, I probably wouldn't have felt any difference, that's how much of a difference it was, not much if any)

No signs of pressure problems, the rounds are not "snappy" at all, empties are not bulged in the unsupported area of the chamber, and primers are perfectly the same size as prior and not flattened at all. I feel confident I can work a ladder upward in .2 increments until I reach the average of the factory loads, if possible. Ill get into to that business tomorrow, and hopefully do some accuracy testing.

This is a fun experiment I must say!

Update:
9mm- 135gr Hydra Shok- DEEP JHP.
5.0gr. BE-86
OAL- 1.118" plus or minus .002
CCI- SPP
FC once fired brass
Glock 19 gen4 Standard
1011fps
1020fps
1022fps
1008fps
1010fps
1018fps

Looks like the low was raised by 10fps, but the top speed only went up by 2 fps. All I really had time for before it got dark.... all looks good on the brass, no pressure signs. Going to go up to 5.2 and 5.4 and test tomorrow...centered a pumpkin behind the chrono and was able to hit all in the center of the pumpkin in a golf-ball (or slightly larger) sized group at about 8 yds. So nothing seems to be wrong with their "combat" accuracy thus far.

Wound up working up to 5.6gr with this load, and it's accuracy is very good, comparable to the factory loads. The average velocities are 1041fps average here, which are right on par with the factory loads.
Accuracy is effectively the same off-hand as the factory loads. The extreme spread is 23 fps which is comparable to the factory stuff...... I'm going to give myself a pat on the back here, I've confidently "replicated" these factory loads.
I'd be pretty confident to say that BE-86 is about as close as one can get to replicating factory defensive ammunition powder in 9mm. Really good stuff.

1. Find what is the Max OAL that bullet will allow in your barrel. The Min OAL for 9mm is always 1.000". That defines a Max and Min seating depth for your pistol. It doesn't matter what the factory does, it only matters what the "fit" in your barrel allows. Now you have a range of OALs you can safely use. Pick one OAL and work with it.
2. 135gr is halfway between 124gr and 147gr. Use the available load data for similar bullets, say for instance Gold Dot. Spit the difference between the 124 and 147gr load data. That will give you a good 135gr "guesstimate" of your Starting Load.
3. Use a chrono. Your Max Load will occur at 1060fps.... if you are sure of that number.
4. Beginning at the Starting Load, fire 6 to 8 rounds of each load, in 0.1gr successively increasing loads, across a chrono at individual targets. Typically (but not always) groups start wide, then narrow down, then go wide again as the load increases. Stop shooting when the groups start to 'open up' again, OR when you reach Max Load as reported by the chrono.

For this exercise I'd be using Alliant BE-86 or Vit N340.
