Smokeless Muzzle velocity

[bobbuck]

Just checking to see if anyone has any load data on a SST 40 cal with 60 gr H 4198 light blue sabot. Need to get a close muzzle velocity for my ballistics calculator. Thanks for any help.

2600ish from a 24" barrel that's fairly tight. Shorter and looser barrels lose velocity fairly easily.

Thanks. I meant to mention it is 25" barrel.

57gr. H4198, Barnes 195, HLB in a 24" is running 2530 or so for me.
