Subsonic loads using Vihtavuori powders???? HELP

[Buckshot]

Hello Kanttori, you just might purchase the current Sierra reloading manual for any info on reloading with VV powder.

Here are some quotes Ï have read.

Starting load: 10.5 grains (Bullet speed = 950 feet per second )

Just let me know if you like the results, since I am planning to use them when my SIG is ready.


Good luck!!!!

I'm going for either Sierra 220grs HPBT or 240grs HPBT bullets. I have 10.5" barrel with 1/8" twist.
