How many load to +P velocities?
« on: October 06, 2019, 06:06:55 AM »
Never would I ever want anyone to ever exceed safe limits to reloading, but I know Accurate Arms publishes +P data on some of their powders. I don't normally do that, but I was curious how many did? And does anyone have the data for Bullseye and a 124 gr XTP?  ;D 8) Just got into Bullseye, nice powder.

I load all my 9mm practice ammo a little on the warm side to simulate the feel of my defensive ammo but there's just no good reason to pound a gun to death on a steady diet of +P. I stay pretty well down from those numbers.
As for Bullseye and a 124gr XTP you can use what ever the posted Bullseye data is listed for 124 gr jacketed bullets just stay with starting data and work your way up.

I load to meet major power factor requirements for open major division of USPSA which is a minimum of 165 PF. Using 115 PD JHP with 7.3 Gr of CFE pistol averaging 1475 FPS, I get about 168-170 power factor out of a CZ Czechmate.

Don’t load this high unless your gun has a compensator and built for this type of competition.

I was trying to do so blindly without a chrono.

But thanks to the helpful “you should stop that nonsense before you hurt yourself” advice I received here - I stopped.  Don’t get me wrong, I am happy that others here are willing to speak out - instead of sitting back while thinking “that guy is an idiot”.  I still need a chrono - since I want to develop a 147gr subsonic load and see where I am at with all my loads, I just haven’t done so yet.

I load for groups, not velocity.  Most of my loads are 8 to 15% below the max. loads listed in the reloading book I'm using (every book is a little different).
I stopped carrying the SIG 556R.  SIG changed models and couple/three times and stopped supporting it with parts.  So, I stopped supporting SIG.  Back to the tried/true AR15 Carbine.

I don't.  For me - no reason to do so.

If I don't it is:
 - easier on the gun
 - more rounds per lb of powder
 - less likely of an dangerous issue in case I do something stupid or such as an issue with an old piece of brass
 - etc

Now, I don't have to constantly train for self defense moves either.
Some trust in chassis, Some in Horsepower, But we trust in the Lord our God.

If it goes "boom" or "vroom" I'm intersted.

For Target/IPSC Match use, I try to stick with loads that produce velocities in the 1100 to 1130 fps range with a 124 grain Bullet.
Standard Pressure loadings for regular usage. 

However, I have made some "Performance Grade" loadings, using Green Dot, HS-6/W540, Unique, and Blue Dot.
Generally, these also involve Jacketed Hollow Point Bullets.  Most have involved surplus Winchester 115 grain JHP's.
But I did make some loadings using some 147 grain JHp's with HS-6/W540 and Blue Dot.
My favorite Powder for "Performance Loadings" remains HS-6/W540.

Never would I ever want anyone to ever exceed safe limits to reloading, but I know Accurate Arms publishes +P data on some of their powders. I don't normally do that, but I was curious how many did? And does anyone have the data for Bullseye and a 124 gr XTP?  ;D 8) Just got into Bullseye, nice powder.

None of my current Hornady Manuals have listings for Bullseye, but my Lyman's 48th lists 4.5 grains of Bullseye as max for a very similar JHP Bullet.  Past Hornady Manuals list 4.4 grains of Bullseye as max for the very short loaded 124 grain Jacketed Flat Point.  Velocities are un-impressive.

For better Velocities, I would look to slightly slower powders such as Unique, HS-6, AA#7, Herco, and Blue Dot.

It should also be noted that some Powders used to load the 9mm during WWI and WWII were very similar to Bullseye, Red Dot, and Green Dot, as they would run SMG's at standard pressure loadings.

Edit Note: In my experience, where Bullseye and it's slightly slower sibling Red Dot shine in the 9x19mm is on 115 grain and lighter Bullet Loadings

I have one 9mm load that chronos over 1080fps and that's a special load I developed for small mammals. I'm using the Berry 124gr Hybrid Hollow Point bullets pushed by N340 to 1130fps. I only went that high because Berry recommends speeds between 1050 and 1150fps.

But even that one is not +P.

Ask me about used Dillon reloading equipment.

But even that one is not +P.

For "small mammals" I normally reserve a .22LR Rifle or .22 Magnum Rifle for such game, but I did develop some "Varmint" loadings for the 9x19mm.

Any 88 to 90 grain JHP over 5.4 grains of Alliant Red Dot produces an average 1450 fps

CCI/Speer 100 grain JHP over 5.3 grains of Alliant Red Dot produces an average 1320 fps

Surplus Winchester 115 grain JHP over 6.9 grains of HS-6/W540 produces an average 1230 fps  (Note: 7.0 grains is max listed load)

Note 1) Alliant Bullseye will produce similar results to Alliant Red Dot in the above loadings
Note 2) Velocities are from my full sized 4.5 inch barreled Tanfoglio TA90, but most full sized Cz and Cz Cloned Pistols will produce similar results
Note 3) Powder charges listed above for Alliant Red Dot are Maximum. Do NOT exceed!
Note 4) The 88/90 and 100 grain JHP Bullets are normally the province of the .380 ACP and will produce dynamic expansion when driven to 9x19mm Velocities
Note 5) Loadings listed above are Standard Pressure loadings
Note 6) The CCI/Speer 100 grain JHP loading and Winchester 115 grain JHP loadings are favorite loads
Note 7) The surplus Winchester JHP Bullet is the same 115 grain JHP as the old Winchester Silvertip loadings, minus the fancy Nickel Plating
