L-I-B. You ended up a measly .1 gr of powder off my load of 39.9 gr.
Yes the Viper is very unforgiving on the eye relief, that's the worst thing about it. A Triad Tactical stock pack can help with this.
And yes, once you go with a vertical grip, you'll never go back.
That's only because I didn't try 39.9 yet. I'll check out the triad. Would you keep searching for a load or go with the 39.8. I don't know that I have the skills to ever shoot better.
And I have no idea what L-I-B means.
Also thanks to all the kind words above.
