RAR 300BLK reloading, pet loads?

[Viper1]

Curious if anyone would share their accurate pet loads, sub and super sonic for the blackout? I have done a few loads for my AR, but my ranch is my first bolt blackout.
Thanks!

I like the 200 grain Makers Expanding Subs from my Rem 700 (Im not an AR guy). I load.them to 1050fps and they are awesome. Zero recoil and expand really well. The load was from Hogdons website. For supers I use the 125 grain Speer TNT pushed with a max load of Lil Gun. The results are very "kinetic"

Thank you! I just threw together some 210grn speers on top of 10.5 of IMR4198 and they shot MOA. So that's promising just sighting the new setup in today. Box 123 gr supers shot well too. Rifle looks to be promising!

125gr TNT over 17.5 H110/296

The only thing I have tried is 220gr fmj wiith 11.5 grains of CMF BLK. It is super quiet and accurate enough for me.

Thanks guys, Dont have the CMF BLK, but have a bunch of other options at home.

For the brief time I had one I used cast bullets and loads that were similar to .357 Magnum.

Don't recall the powder dose, but 125 gr speer tnt over 4227 was outstanding when I had a 300 bo AR.

So far, using 210gr sierras, IMR4198 (11.2gr) and 4227 (10.5gr) are giving me some awesome groups. I have some 190gr lehighs to test soon as well. These 210gr will just be plinking rounds.

I found 190 Nosler HPBT to be fairly accurate using a close to max charge of H110 or WW296. A slightly lighter load using AA#9 also did well. Altered 5.56 military brass won't hold quite as much powder as factory made 300 cases--just a reminder. I had a bit of trouble with the heavily compressed loads forcing the bullets out of the case unless firmly crimped.
