Just entered the 300 Blackout Club

[Olympus]

After years of not getting on the bandwagon of 300BLK, I finally decided to jump in. The whole super/subsonic options seemed to fit into a lot of niches that I have. For hunting, I'm a recoil sensitive shooter so 300 super sonic seemed like a great fit for hunting whitetail at shorter ranges than I would normally like to do with my 243. So I have a Ruger American Ranch Rifle on the way. And since my state has a seperate season for handgun hunting, a 300BLK AR15 pistol would be a great way to add another season to my fall deer hunting. So I will be building a 8.5" or 10.5" upper coming soon. And since I've been thinking about paying my SOT and selling suppressors, I could get into subsonic shooting very easily also.

300BLK may not be the perfect caliber, but it seems to fill a lot of my wants and needs. I've already started getting some rounds loaded up for my Ruger load workup when it arrives.

Congrats Olympus sounds like fun I suggest a SBR as well

Already have an SBR lower I can use the upper on also!

I did just that this year and nabbed a nice 7-point white tail this year from a bow hunting stand. The "pistol" was very handy on that little stand and dropped him as pretty as you please from 30 yards.

The trick to the AR 300 BLK for hunting, in my opinion, is finding the right bullet. Most of the .30 caliber bullets either 1) wont feed properly in an AR or 2) wont expand at the velocities that .300 blk achieves. There are a few 200gr+ bullets that will expand at subsonic velocities, but they run in the dollars per bullet range.

I ended up going with 110gr Barnes TAC-TX's for hunting and anything above 200gr that I can nab cheaply for subsonic plinking.

I also found that a 10.5" barrel with an H3 buffer cycles well in all four modes: suppressed sub-sonic, suppressed super, un-suppressed sub, un-suppressed super.

And I just did a reloading calculator for my loads and came up with $0.16/round for subsonic loads and $0.26/round for supersonic loads using the Hornady SST bullet. That's a lot better than I expected.

Hey Olympus that's great

 

[Olympus]

Don't know what I think about the scope yet.

I load mine with 150 grain Hornady FMJ's. I bought a 2K case of them over the winter. That and some H110 and I was ready to go. They shoot well. Don't have an AR or a Ruger. I make due with a Remington Model 7 AAC Blackout. All brass is converted using a jig and the mini saw method. Very workable. Love the round. I do have a lead mod for 220 grain bullets. I haven't tried any yet. Don't use it for hunting. The GSR or the CZ527 get the nod in that department.

I haven't found that it will do anything that I already have won't do but you can't have one of everything without one I guess.

Other than no illumination, which you might need for hog hunts, I've heard mostly good things about that Nikon scope.

Which bullet again? Unless it's 199gr or more, you won't be cycling subsonic loads in an AR.
