No they won't fragment like the 77 grain SMK; they fragment BETTER! As mentioned above they can be loaded to magazine length and if you do your part, the bullet will definitely do its part in the accuracy department.

The 75 is a great bullet, I have never got best accuracy at max velocity with it, but that is probably just my rifle. It is accurate enough and has great terminal ballistics. It would be my first choice for SHTF reloads. Nosler 77 CC second, SMK or possibly Prvi 75 OTM third/fourth. Molon, what would your ranking be?

Real close to yours, except I would put the Hornady 75 grain BTHP and Nosler 77 grain CC tied for first place (and keep one magazine loaded with a barrier load.)

A most excellent load:

75 gr Hornady HPBT-M bullet seated to 2.235"
24.0 gr Varget or 23.0 gr TAC
Winchester small rifle primer
Winchester case

OR

I take a magazine into the reloading room, seat the 75gr Hornady's bullets out as far as I dare and test fit every round for function.

It's an extra step but it pays off in the end

My, my! 2800FPS! Please note, you will not get that gelatin block result from your AR unless you stick the muzzle right up to the gelatin block and pull the trigger. That being said, thanks again for the terrific photo's.

So, does anyone have a lab test result comparing fragmentation from the 75 and the 77 gn at some respectable distance say, like 25 yards?

I would not do this if I were you. If you do, be sure to check the slant height , as opposed to the OAL. If teh cartridge is truly near the max length for the magazine, and then it gets tipped in the mag, it could get wedged in place causing a jam.

The Prvi 75 OTM did rather well in gel tests too though, didn't it? I seem to recall a post of yours about that. Accurate and good fragmentation.

Serious?

I was getting 2850 fps thru a 20" SS barrel w/o any pressure issues....new brass...

I down loaded to 2780 fps....just to not worry about

I don't think he was being sarcastic, 2800 fps is 150 fps faster than I run them in a 20" barrel. I only get 2720 from a 26". I haven't tried to load hotter because I consider this good velocity and the load just hammers as is. Most reloading manuals max out at 2600 to 2650 from a 20" barrel.

My question to CCW has absolutely nothing to do with your above babbling. It pertains specifically to the positioning of the gel block in relationship to the muzzle of the test weapon, hence my specific editing of his quoted post. Also, for your edification, the Black Hills loaded 77 grain Nosler round had a muzzle velocity of 2848 FPS from my 20" NATO chambered Colt barrel

My humble apologies. Your Black Hills 2850 muzzle velocity and my Dr. J's External Ballistics program shows one could step back 17 yards and achieve the 2806 FPS found on the photo. I suppose 17 yards would qualify for good CQB action.

Found a BLC(2) load for 2804 FPS Muzzle Velocity out of a 20" bbl at 50,700 psi. chamber pressure.

What is the Black Hills chamber pressure?

BLC (2) is too fast....run something like AA 2520....no issues in my gun at the 2800+ fps...your gun may be different...get a chrono if you want to shoot on the edge...
