Help Please in Reloading 9mm

All,

Thanks in advance for your time and information. I have a new round to reload, and with four manuals and all the online data, there isn't anything to guide me.

I have just purchased 9mm 135 grain LRN (yes, 135) bullets from BlackAndBlueBullets.com. I purchased the 135 instead of the 124 or 147 as an in-between, trying to keep costs down but easily hit the minor power factor of USPSA.

There isn't any data for this bullet size. Do I just take the 124 and the 147 and find a middle ground? The concern with that is the difference in powders, and the availability of powders.

For powders, I have two pounds of Bullseye, 1 pound of Titegroup, and two pounds of Hodgdon HS-6. Powder has been very difficult to find in NW Oregon.

How do I find data or start with minimums to put these rounds together?

I would take the data for the 124gr and the 147gr and split the difference.

Ex: 124gr = say 6gr of X powder and the 147gr shows 5.1 of X powder then I would load 5.5 less 10% and work up or down from there.

Not scientific but has worked for me for years when faced with odd bullet weights.
 
Splitting the difference is a viable approach.

If you really wanna err on the side of safety, you could just start with 124gn data. Don't overthink this. Pick a common sense amount and proceed.

I don't know what the USPSA power factor is (I shoot competitively, but not this discipline), but I'm sure either Bullseye or HS-6 will get you there (I have no experience with Titegroup). One of 'em will do what you need. HS-6 runs cool, and that bodes well with lead.
 
Good lesson for "always find a load in one of your manuals before you buy components". Perhaps you can contact the bullet manufacturer for load data. I don't like trying to "extrapolate" a load from loads designed for other components. I wouldn't "average" data...
 
Send a note to the vendor and ask him for data. If he's manufacturing the product, the least he can do is help his customers use it properly and safely.

Good luck. Be careful.
 
here is some chrono data from that bullet
i got some samples from Tony at black and blue
and i wanted to see how it worked out with CSB-1

Description: 135gr rn .357 hi-tek Black and Blue
Notes 1: 3.7-3.8gr csb-1 1.130
Notes 2: 1911 FS
Distance to Chrono (FT): 10.00
Ballistic Coefficient: 0.117
Bullet Weight (gr): 135.00
Temp: 35 °F
BP: 30.06 inHG
Shots
# FPS\FT-LBS
8 985\291
7 989\293
6 928\258
5 962\277
4 945\268
3 947\269
2 992\295
1 970\282
Average: 964.75
StdDev: 23.40
Min: 928
Max: 992
Spread: 64
True MV: 974.15
Shots/sec: 0.38
Group Size (IN): 0.00

that makes minor (mind you from a 5" 1911)
but not buy much
so try and get it a bit faster
get it to 1000 fps for a safety factor if its a 5" gun if shorter than you ll need more powder yet to make up for the shortness

with this kind of weight bullet CSB-1 crosses almost perfectly with Universal

with that info you should be able to come up with something real easy
dont have to try to hard

and as always
never use info from some random poster on the intertubes :eek: with out due research

Minor PF for Uspsa is 125, I haven't been loading long but those that have told me to shoot for 130 PF, that way there's a little leeway for temp variations, charge weight variation, different brass, etc. Hate to get DQ'd over a few fps
