after reading this the other day it prompted me to have a play with these loads. I also have 26" barrel on my AI, I can load these bullets long, so ive upped the powder charge slightly. COAL 2.890" 45.5g N160 with average speed 2921 fps with a spread of 6fps over 6 rounds. THIS IS OVER MAX LOAD LISTED IN VIT DATA, BUT I HAVE WORKED UP TO THIS!! and with the bullet way longer than SAAMI COAL allowing additional powder. do NOT start at this load!!!and how are the results ?

Cheers for the feedback
and of course i hope that all who read these threads understands the importance of slowly building up loads in a safe manner, and absolutely not starting at max

That seems pretty stout - that load is Viht’s max for a 123gns bullet.
I use 45gns of N160 for the same bullet and was getting pressure signs at 45.5; interested to hear if you are seeing any bolt swipe marks, flattened primers etc…

None at all, but as I say I’m loading to within 8thou of rifling, giving a long bullet and obviously more cavity behind it. Loaded COAL 2.890. I tried 5 rounds at 46, and although still no signs of pressure, the spread was close to 30fps, with 45.5 I’m getting 6!That seems pretty stout - that load is Viht’s max for a 123gns bullet.

Something else to add here, to anyone else who might read this thread! these are lead bullets not copper!!!
Personally I just look for the data to start up point and work up . After i have cross referenced in various different guides ( books and manufacturers online data ) even these will vary . To get things more correct i will search carefully for the "too much" on a hot day .
Now most data can be found on the net free , its a lot easier

Any ideas on a load for a 130 cx

Lucky youSorry no. I am copperfree thus far….
wish I was staying that way 130 tmk just gets the job done
look within the online data across the board for the similar weight and work the load up looking for pressure sign . As you are working up from lighter loads and checking pressure sign you will be fine , if you don't understand get experienced help .Sorry no. I am copperfree thus far….
equal weight to lead with copper is fine so long as you start at the start load . I find this totally fine with modern copper bullet design
