124gr lead RN questions

[Wobbly]

Just to update my issue with not really liking the 147gr lead................ I think I know what part of the problem may have been. When I came downstairs tonight to determine my oal for the 125gr LTC, I realized that I had never done this with the 147gr. I was using an oal of 1.148. After doing the plunk test, I determined that my max oal for the 147gr was 1.122.

That's big. So when the slide slams forward, your ammo is being foreshortened to different OALs each time. That would do it.

What an idiot I am.

We don't allow name calling or "bullying" on this board. If you can't come up with more polite names for yourself and stop pushing yourself around, then we'll have to ask you to leave. We're going to let you go this time with 20 pushups and a public apology.

I just cranked out 40 push ups. As soon as the doctor lets me off the oxygen, I will write up a public apology. Please don't make me leave! I just got here.

[Wobbly]

Apology accepted.

Now back to our regularly scheduled thread.

Loaded up a few test rounds with the 231. I will post results of the loads on Sunday after I test them or maybe Friday if I can get off work early. My impression of the 231 so far.

Pro: Very consistent throw from my loadmaster
Con: Cannot load below 3.1gr on my loadmaster. That's the smallest throw through the smallest hole available.

I will be testing loads with 125gr LRN and 125gr LTC and every powder I own. 231, unique, wsf, and clays.

So I got home early today and my chrono was sitting on the front porch so what do ya think I did? That's right, I shot some rounds down range. Here is the info I retrieved from my testing of the 125gr LTC from Lucky 13 using just the 231 powder because that was all I had loaded for the 125.


Elevation 600'
temp 70
wind blowing in my face about 10 MPH
Avg bullet weight 130gr
Mixed Brass
CCI #500 primers in all the loads


3.1gr 231
1.010 OAL
Avg Velocity 896 FPS
PF 116


3.4gr 231
1.010 Oal
Avg Velocity 955 FPS
PF 124

As you can see, none of these loads met minor power factor. I also tested some loads that I had loaded already in the 115gr plated and the 147gr lead. I will go ahead and list those results as well

115gr LRN RMR
Avg weight  115gr
5.7gr WSF
1.148 OAL
Avg Velocity 1059
PF  119

147gr LRN Lucky 13
No avg weight. I will have to pull some bullets to determine.
3.5gr WSF
1.130  OAL
Avg Velocity  862 FPS
PF 126 assuming an avg weight of 147gr


147gr LRN Lucky 13
3.5gr WSF
1.120 OAL
Avg Velocity 876
PF 128


147gr LRN Lucky13
2.6gr Clays
1.120 OAL
Avg Velocity 851
PF 125

DISCLAIMER: Do not trust any of my loads. They worked for me but might blow up on you.

[levellinebrad]

Did some more testing with the wsf.

11/8/13
68 degrees
elevation 600'
wind was calm
mixed brass
cci #500 primers
LTC's avg weight is 130gr
LRN avg weight is 125gr

125gr LTC lucky13
3.8gr WSF
1.010 OAL
Avg velocity  949 FPS
PF 123

125gr LTC lucky13
4.0gr WSF
1.010 OAL
Avg velocity  998
PF  129

125gr LRN Lucky 13
4.0gr WSF
1.148 OAL
Avg velocity  966
PF 124
Probably need to shorten OAL on this load.

All loads were accurate. Recoil was minimum with the faster load having more recoil but still very manageable for fast 2nd shot.

Half the fun is testing loads till you find the sweet spot. Then you'll have to test them at 25 yards to make sure there accurate.

[levellinebrad]

Yep. I saved some from the same loading session so that I can test accuracy at the range. I need to get the quick load software so I can estimate pressure.

More Testing. This time with Win 231
Temp 48 degrees
Elev 600'
CZ SP-01


125gr LTC lucky 13
 3.6gr win 231
 1.010 OAL
 Avg Velocity 992 FPS
 PF 129

 Kinda smokey
 Nice pile of brass about 3' to the right
 Recoil is manageable

 125gr LTC Lucky13
 3.8gr Win 231
 1.010 OAL
 Avg Velocity 1027FPS
 PF 133

 A little more recoil obviously
 Brass in a tight pile about 4' to the right
 Still smokey.

Accuracy was acceptable on both rounds. I think I will test Clays behind the 125gr next
