Quiet load recommendations
 
I've been shooting 220gr rounds with H110 in 9.1 and 8.9 grains. I have a Yankee Phantom suppressor on my AR with adjustable gas port(http://www.yhm.net/store/phantom762.html), but I am no where near to being quiet enough that I can shoot without hearing protection.

What are your "quiet load" recommendations?

Thanks

You should be under 130db & that's ear safe.
W/762sd I'm in the low 120s.
You're not getting any sonic crack are you?

try 8g of 2400 with a 147g to 150g bullet

I use 8.0gr of LilGun for my 220's thru an SWR can and they are very quiet.

No, I'm not getting a sonic crack, and I'm less than 100' above sea level. My shots aren't quite as loud as a high velocity .22lr, more like the report of a .22 short, but I would still like to reduce that sound level.

I chose the Yankee Phantom supressor because it was very highly recommended. Without having to spend $$$$ on suppressor experimentation, I thought I'd experiment with different loads and get the opinions of the fellows on this forum.

Thanks to everyone for their recommendation - keep them coming!!!

What are those fellows on YouTube using??? :wink:
