@300_BLK those Barnes 110gr ttsx's look the biz for deer up to 150m?
Same guy was making 200 gr flat noses and I made a jig to drill em out to about 180 grain.
Rule of thumb for subsonic load dev is work your way down teh charge weight slowly. If you are running a rattle gun BLK then get an adjustable gas block or H3 buffer and make sure it will lock back on empty.
Yeah your on to it there @Timmay. They are very good pills, but as i'm a bit of a scrouge i like the 125 SST hornady developed for the Blackout.
I think the a Ruger American in 300 BLK migh replace the AR upper. Quieter and I find that a lot of my shooting with the 300 is with the kids / wife or for deer.
I hate chasing brass after culling goats...
Barnes tsx/ttsx sure are spendy. The 110 a or v max from hornady has a scary ballistics jell image in their page, like 1-2" in then it fair blows up.
125 ballistic tip have excellent penetration and expansion with the 300 black.
Have also used the Barnes ttsx-Tx 110s in the Ruger ranch definitely the ducks nuts for further out with the 110.
The nosler 125 tho's cheaper and has been easier to get so.... both have been awesome....
My go to was the Hornady 110 Vmax for supers - performs well to 450m and acts more like a conventional hunting pill at Blackout velocities.
If you want cheap 'Hammer of Thor" performance look at the 130 Speer HP.
Just wondering if anyone has a good recipe for lehigh 194ME or 168CF in this rifle? I'm hoping for a good starting point so I can get something to work before I reach the end of the box, which usually happens to me Haven't got any better than about 1.6MOA so far with 125gr SST and 220gr SMK in my RAR.
Thanks Tikka,
Results so far, COAL = 2.240
9.0gr H110, 3 shots, 1MOA
1088, 1047, 1058 fps
9.5gr 2205, 3 shots, 1MOA
1089, 1075, 1091 fps
So far this is the about the most accurate bullet I've tried. A little fast, I always get vertical stringing if I try and reduce the velocity on the 220 SMK's even if I seat the bullet back, tried a compressed load too. I might try a different suppressor, mine's weighs about 450grams. Did you have any work done to your rifle other than the new barrel?
Thats definitely better, the other thing I can suggest is weight you brass into 2 or 3 weight batchs that made a difference for me.
Also I run every batch through a chrony and have each batch separate and use one batch at a time then go onto the next, I've got 13 or 14 different reload batchs of 194gr Lehigh ME, 208gr Amax subs and 125gr BT supersonics. It keeps the ES down for each batch and better MOA. It only takes a couple of clicks to re-zero between batchs. Maybe a lot of work but need best accuracy for hunting with 300 Blackout at distance.
Work done on rifle was trigger lightened by me, and halfcock bolt, new barrel with it threaded for a ODL suppressor by the gunsmith.
Thanks Tikka,
I've been weighing brass too, found a big variation with Hornady brass. For your long range work, did you find your drop matched your calculated solution? Mine's about 1.5Mil lower @300M. I might need to do the tall target test.
Did a tall target test and had an error of about 1.5%, accounting for that, G1 BC of 0.27 matches my drop at 300m. about the same as flat nose 30/30 of the same weight. https://www.sierrabullets.com/store/...0-30-170-gr-FN a bit less than advertised 0.630. holes a little bit oval shape out of 1/7in twist. Group was 1.8MOA (3 shots)
