40 S&W 180 gr fmj w/n320 data?

[Pw]

Does anyone have some accurate target loads using n320 w/180 gr fmj's? Oal length I'm using is 1.135.

Most of the loads I have logged down are in the range of 5.0 with a max of 5.3gr. But the OALs are a bit longer at 1.15-1.17in. The loads are from an IPSC/USPSA list of "pet loads" for competition pistols. The loads on it for N320 are in the 940-990fps range.

As usual, use the data at your own risk.

Vihtavuori only lists n340,3n37 and n350 for 180grn hp (in my old manual)

Speer lists n350, and 3n37 for 180grn

Sierra lists 5.2 max at 1000fps 1.125oal. for n320

Hornady only lists n340.

Seems pretty limited with that powder.

Thanks for the replies. vv lists 180gr lead data w/ 4.1 max. Sure im safe w/ start load of 4.1 and stick w/ 5.2 as max. some room there to watch for pressure signs.
