Sub 300BLK with Titegroup

[waco]

Ruger American Ranch 300BLK
Lee 312-155
Titegroup
Subsonic
Can anyone tell me where a good place to start is?
5gr? 6gr?
Just looking for cheap accurate fun.
Many thanks.

I'd start here, https://rebelsilencers.com/sos-hunter

Then go here: https://www.atf.gov/firearms/docs/f...-registration-firearm-atf-form-53204/download

Then go here: http://www.neconos.com/details3.htm

You'll end up here:

I do subsonics in 300BLK with heavier bullets, like 190-220 Jbullets. For them, 9-10 gr
of H110 do great. Never tried TG for this application.

Let me run some QL data for you. Will get back soon.

I also use H110 with 22gr cast boolits. If there's a load for using titegroup I sure would like to learn.

4 grs.
I'm at 3.5 with 700-x it's as low as I can go.
4 grs of the fast powders is right at about the sweet spot as far as enough load density and velocity etc.

4 grains sounds about right under a middleweight cast bullet in the BLK.

6.4 grains of TG is my go-to sub load with 230-grain cast bullets...in 7.62x51mm U.S. -spec machine gun brass. .308 Win brass might need a couple tenths more powder due to the extra room. The same bullet in the tiny BLK case will need a LOT less and as Fiver and others talked about here many times TG gets stupid with pressures real quick if you use too much in a tight space behind too heavy of a payload. With a middleweight bullet 4 grains still should be well between sticking the bullet in the barrel and blowing things up and with chronograph data you can tell real quick which way to go from there. I'm not sure I'd even try TG with heavy jacketed bullets, especially the tough ones designed for the hyper-velocity magnums.

 

[fiver]

there is no way I'd try it with a heavy jacketed.
you'll have room in the case to work with but the engraving pressure of the jacketed bullet could spike things much too sharply for me to be comfortable with the combination.

Thanks for the responses guys. Just thinking of a fun cheap plinking load. That Lee bullet does real well for me with 15gr of IMR4227.
This is a fairly zippy load. IMR4198 might be a good option for some faster stuff too.
Anyway, back to the point. 4gr of TG sounds good. I have lots of Redot also. This might be a good one as well.

 

[Brad]

Red dot might be better. If life lets me find time I can get some QL data run

 

[fiver]

4 grs of red-dot will work too.
ghosthawk regularly shoots 4grs of it in his BO.
you don't need to jump up in weight for more velocity [about the same pressure] until you get to about 5grs of green-dot, and then again on the other side of herco.
