Supersonic accuracy loads

[1911man]

Anyone out there willing to share their accuracy/hunting loads with me? I'm playing with 1-8 and 1-10 twist in both 11" suppressed and 16" non-suppressed with a 300AAC chamber.

My bolt and AR both have 16" barrels and both shoot 125gr Nosler BT over 18.0 gr 4227 very well.

What's your OAL ? I have found OAL to be critical with the 300AAC/Whisper/300/221

So far I'm having best results with the following:

Sierra 125gr PH, 18gr H110, 2.060" OAL
Nosler 125gr BT, 18gr H110, 2.160" OAL
Barnes 130gr TTSX, 18gr H110, 2.160"

I'm using 2.050" with the 125 NBT and the seirra 125 spitzer.

Best results for me have been with the 125gn Nosler Ballistic Tip and 17.5 gns of N-110.

Out of my 16.125 inch bolt gun they are going about 1980 fps with single digit ES/SD.

It is a hammer on coyotes and very quiet even though I am using a SF 338 suppressor and not a 308 suppressor.

Are you using a Whisper or 300 BLACKOUT chamber?
