Here's where it gets odd...

I'm sorta stumped as to why .2 g higher charge and a shorter OAL would show a drop in speed?

Also loaded up some Winchester autocomp

No pressure signs and my primers look good. The 3n38 shot softer at the same PF

I plan to load more of each for a side by side test at some point. I will update my findings.

Thank u all for looking.

The loads listed are for educational purposes only. Do NOT replicate my data. All guns, barrels, and components are going to slightly differ. Bla bla bla PLEASE DONT BE STUPID.

that being said have a wonderful day. :-)

I shoot SP2 and VV claims 3N38 is an equal so it might behave similarly: I shoot 115gr bullets @ 1.160" and when I loaded more than 9.5gr, the velocity started to go down; 10gr actually yielded less velocity than 9.5gr. At a shorter OAL with a heavier bullet I suspect you hit the same point at a lower charge weight.

Yep all loads eventually plateau.

Sorry for the double post I didn't see that until now. I love the 3n38 load it was very soft and very flat. I think I will load a few at 7.8 and see if I can get a reliable 165 and that will be my ipsc comp load. Perhaps keep experimenting with the autocomp at lower loads and n go from there.
