Charge weight vs. MV and Pressure

[res45]

Hope I word this question right or someone can read between the lines,I just got my chrono but due to weather conditions setting it up and running some test will all but be impossible at least for this upcoming week.

I'm using Alliant 2400 and the Lee TL GC.312 160 gr. cast from WQWW alloy with a BHN of 28. I can't seem to find any MV date using this bullet and 2400 in a standard 20" SKS. I know I can get the specifics data when I do my own test but I was wondering if anyone had any chrono data using various charge weights of 2400 and the Lee cast bullet.

I'm using 12.5 grs. on the mild load and 14.0 as my warm load so to speak,I don't see any reason to push it up to 15.0 grs. just wasting powder when the other two function and shoot so well. Thanks

Well Mr Harris responded to my and older post on using Alliant 2400. I can expect somewhere around 1300 fps. with 12.0 grs. and 1800 fps with 15.0 grs.

Another poster gave me his results 12.7 grs. 1576 fps avg. and with 14.5 1692 avg. I guess I will see how my loads stack up.
