300 blackout bullets.

I have used some for range fodder. I bought them for something else that did not work out. I don't remember having any issues but I don't have my notes handy.
 
I haven't found any real justification for using mid-weight bullets. If I am looking to construct plinking ammo, I keep an eye out on American Reloading for 110gr vmax pulls or shooter's pro shop for 220gr custom comp blems...

both shoot very well and I wouldn't hesitate to use either in a crisis...
 
Is anyone using just 30 cal, 30-06, 308, bullets in the 150 range?
There are a few threads on the forum with recipes for .300BLK and the majority of loads are for 100gr-135gr or subs with 190gr-225gr. The more common .308cal bullets from 150gr-175gr are certainly useable, but are not exactly optimal for most applications other than punching holes in paper. One thing to be very mindful of with venturing into loading the 135gr-175gr bullet range is powder selection and keeping pressures under MAX. I think you should be ok with Hodgon CFE Black or IMR4227 while Win296 and H110 will likely be a bit too fast burning for the heavies.
 
They work fine. They just won't have optimal terminal performance due to the reduced velocities. Because they are designed to work at higher rifle velocities.

I use 150 gr hornady soft point flat base bullets for 308 and 300 BO hunting ammo. Both work great for me.
Are these expanding for you? Are you using a longer =>16" barrel in the 300BLK?
 
*Supposedly* those aren't quite as efficient for the twist rate of typical 300blk barrels, and they don't quite have the optimal performance you get out of 110-120gr supers or 220gr subs. The only reason they really got popular AFAIK is they're cheap and plentiful for bulk 7.62x51 handloading. Personally I use 110gr and 220gr since that's what works well in my 300blk AR.
