Home Forums Hunting & Shooting AR and Tactical Rifles Favorite 75g hornady bthp ar load

Wondering what your favorite ar load is for the 75g hornady bthp. I'd prefer a powder that meters pretty well so I'm staying away from varget and rl15. I just loaded some with benchmark and 8208. I also plan to try ar comp, tac, leverloution, cfe223, pp2000mr and maybe a few more. I'm hoping to find a load that shoots well in several ARs and has decent velocity. Once it's figured out I'll load a bunch on the progressive.

24gr of TAC work well for me. Accurate in all my rifles.

Thats about right for TAC, IIRC we were at 24.2 possibly.

RL15 measures plenty close enough too, FWIW, a few tenths won't make any difference on a good load… loaded a LOT on Dillons….. with RL15...

We changed out the dillon P measure for a case activated Hornady measure. 24-24.5gr RE15 has worked too well for a long time for me to waste time experimenting.

Dillon throws em well enough as is, that i can't recall how many matches we won using the dillon measure.

24.5 TAC has worked well for me. I get very consistent throws with TAC.

RS's book max for 5.56 is 25.8.

23.2gr of 8208xbr is my 75/77 gr service rifle load. Also shoots well in a 16" DD lightweight barrel of mine. I've seen people report 23.8gr is a good one too. Meters good enough in my Dillon measure for NRA HP shooting, although I use something else to measure the 80gr 600 yd loads.

Reading that... maybe our general tac load with 77s was 24.2... no clue where all that data is buried right now... a LOT of testing across a range of barrels went into that issue at one point when TAC was new...

My rifles crapped primers at 25.8 of TAC.

I don't doubt it. 24.5 will usually run about 2700 depending on the bbl and seems to be fine on pockets. That seems like enough speed to me, but the book loads near 3k are interesting.

My latest bbl is a Rock/Seekins 16" chambered in Wylde. 24.5 did fairly well on the first outing, but I may end up tweaking it a bit.

Good lord, I bet they did. That's over a full grain from where my rifles show pressure signs with 77's.

77s and 75s seemed like different beasts years ago.

Yep the 75 Hornady's will take more powder than the SMK 77's.

24.5 is about tops on the 77 SMK's in every barrel I've tried but I don't recall where I was with the Hornady 75's as top velocity seemed to open groups up quite a bit.

Hornady bthp, not the amax, could always get more speed than the SMK. But it could not do it and remain competitively accurate at the same time....

This was years ago though.

Yes HPBT's, only crazy folks would try the Amax's in an AR.

duly noted. LOL

25.6 gr CFE 223 works great in my AR.

I've got lots of Tac and RL 15 on hand. I've played with the Tac some and found a load in my 8 twist t3 varmint that liked it and ran .2's several times but I keep getting weird inconsistencies in my ar's and 223 ai with tac. Just when I think I've got a working load it doesn't work anymore the next time out.

Tried this load. Accuracy out of my 16" PSA SS was ok but only gave around 2500 fps on the high end.

Also tried LeverR. Oddly, 24.7 gr worked out of my RAR aswell as the ar. Got about 2725 fps with AR (2850-60 with RAR if anyone cared). Blew some primers at 26grs so I backed off.

There is no published that I could find as far a Lever R being used with 223/5.56, you are playing with fire if you are using a powder that has not been tested with that cartridge.
