I don't have the Hornady manual yet, Hodgdon doesn't list them, nothing in stickied reloading database.  Search for "Benchmark" turned up nothing in last 30 days.
In case you're wondering: 24" 1:8 twist heavy-barrel AR.  Thanks!

I'll reserve this space for tomorrow when I can get to my manuals.

I really like Benchmark as a powder.  I buy it in 8lb jugs, and always want at least one on hand. it is the basis for the two loads that shoot very well across my three AR's (two 1-8" twists, an HBAR and a Varmint, and one 1-7"  carbine) and two .223 bolt rifles (1-9" Savage LRPV and CZ 527 Varmint).  

I also really like 69 SMK(s) and Hornady 75 OTM(s).  Both are great bullets, the edge going to the 69 SMK(s) in my rifles.

From what I've found testing with Benchmark is that it did better for me with lighter bullets in .223 Rem, the upper end being 55 grains.

RL-15, Varget, and 2520 do the best for me in the 69 Gr and up weights.  TAC also shot reasonably well on the heavier end, but not as well as Varget/RL-15/AA2520.

Benchmark excelled for me with 50 V-Max and 50 or 55 Gr Ballistic tips.

Quoted: You won't find data for .223 Rem in the Hornady manual for bullets heavier than 60 grains. Hodgon's on line data has loads for bullets to 80 grains.

My Hornady manual has data for the 68 and the 75 grain  BTHP Match. Under "223 Remington Service Rifle Data".
But not with benchmark.

I have the new 7th edition Hornady Handbook of Cartridge Reloading.

Wow, according to the Hornady manual, I'm .5grain overcharged with Varget on my 75gr OTMs.

Good luck with your Benchmark search.

Please Don't feel That the context of my post "meant" that you did not "know" that. I see that you edited your original post to include the word benchmark -  so , now , no one can misinterpret your posts. I do not feel that my post  with the information that I included, was "off topic". Actually, The info I posted, is in fact "on topic" and hopefully may help the original poster - as he asked about 68 & 75grain hornady BTHP Match , although "benchmark" is not listed in the data I provided. I see no harm in adding that info. You do not need to be so defensive just because the word Moderator follows your forum name. Remember, you are human too

Checking out Hodgdons online data,  they seem to list 69 grain, and 75 grain bullet weights - although they are NOT Hornady, they do list loads using Benchmark -this might help. Hope this is not "off topic"

Thanks everyone for all your help.
Is there any significant reason I couldn't use Hornady's data for 75gr VLD bullets to load 75gr BTHP bullets?

Seems that Hornady's manual is a bit more conservative than others I've seen.  Example:  Hodgdon lists max charge for 69gr HPBT @ 26gr (C) of Varget (3010fps)
Hornady lists max charge for 68gr HPBT @ 24.9gr of Varget  (2800fps)

Thanks again.

I use Benchmark under 75 grain Hornadies.

The 75 grain Hornadies fly best between 2750 and 2800 so adjust your load accordingly.

I use 22.0 grains in my 26 inch Pac Nor on my Remy 700.

I just loaded up some with 23.o grains to shoot over the chrono from the new 20 inch Lothar Walther on the SPR.

I'd like to know this as well.
