Accuracy of your SBR 300 Blackouts

Post by Jeff in Texas » Sat Dec 10, 2016 1:54 pm

For those of you shooting 10.5" or less/more barrels on the SBR 300 BO what kind of accuracy are you getting at 100 yards? What's the accuracy of your supersonic rounds as well as your sub sonic rounds. Someone on another board a while back posted he was getting sub moa with subsonic rounds at 100 yards? Sorry, I felt there was way too much Hollywood in that statement!

What real world accuracy should I be able to expect?
Distance is not the issue, but the winds can make it interesting!

Sub MOA with supers is no problem.

Subs is a different story. Not that it can't be done, but your loading technique needs to be spot on. 1.5 moa is probably more realistic.

Grab a ballistic calculator plug in a 50 yard zero then see the difference in drop at 100 yards when you vary muzzle velocity 15 fps. Basically that alone will will change your group size 3/8". It's not that it can't be done, it just takes a little more work.

It's a lot to sort through but there were a couple groups posted here with SBR's. Might have been a couple better than 1.5 MOA at 200.

300 Blackout, not just for sub-sonics.

I have only shot 100 yards a couple times with my 300 bo with a 8.5 noveske.
Around two inches. I will improve on that number though.

I'm getting ~1.5-2 MOA from my 8.2" Noveske and 220gr Leatherhead's with a Saker 762.

I'm shooting under 1/2 moa at 100 with reloads. 12.5" barrel but in a bolt configuration.

With factory ammo, I have found several rounds that my Odin 10.5" shoots well, and some that it doesn't.

For supers it loves Remington Premier Match (sub MOA), and it likes Remington UMC 120 and Barnes 120 decently (1.25" or better). Barnes 110's don't do as well (1.75" sometimes a bit better).

Subs, I have not and probably will not hit consistent MOA with a factory load (for the reasons stated previously), although the remington 220's (green and yellow box, not the UMC) have surprised me a few times, as well as stuff from Gorilla. The gorilla Silverback subs have been .75" at 50 yards, which is plenty for me for close range deer hunting.

Reloading is in my near future, mostly for the quest of an accurate, expanding sub load for hunting a bit further out.
