BWE,
Thanks for the info. I know that the 300 Whisper and 7.62x39 are completely different but I was trying to see what the 300 can offer over the x39. I was thinking about future projects and the 300 is always popping up.
I'll order Quick Load ASAP, thanks for the tip.
As for the H110 and low powder charge I am concerned as well. It was the one powder charge that gave me fluctuating velocities, while testing my other subsonics, and I'm pretty sure it was the low charge/s allowing the powder to lay flat in the case.
That's why I was wondering how much powder could be loaded under the 200gr D166. The 18gr filling the case to the bottom of the heel looked like a great idea but I wasn't about to test it without asking.
If by chance, do you know of a good alternative powder in which 18gr +/- would be able to get a 200gr bullet to travel supersonic without blowing the rifle or myself up? If not off the top of your head I'll play with Quick Load.
Thanks again,
Scott
