Let's keep this thread as the "go to" place for the 147-152 gr & 168 gr loads.
I hate to keep buying powders and failing. It seems the reloading and component companies are not giving us much data on these weight bullets either, keeping us in the dark. Again it's 110-130 gr then the jump to the subsonic heavy bullets skipping the cheep popular middle weights.
I agree completely John. I asked the same question here http://www.300blktalk.com/forum/viewtopic.php?f=141&t=78480
The 300 Black has been SAAMIed for a year now. A year for crying out loud. Data is almost nill.
Like you said above the "CHEAP POPULAR MIDDLE WEIGHTS"
get no data. I DO NOT want to use Whisper data that many people point to. By doing that you make the whole purpose of being submitted to SAAMI worthless.
Paying top dollar for "light weight" bullets that are boutique in nature, as in super duper match bullets, is not
what MOST people want.
They want to PLINK, shoot a bunch for cheap, enjoy an afternoon without burning a hole in your wallet...type of shooting. I like it that much that I built a dedicated AR to shoot only 300 AAC Blackout
. No changing uppers and crap like that.
