Re: New Hornady 178 BTHP load
If there's an issue with the lot numbers and I have ammo in those lot numbers I would rather not shoot it to find out.

Re: New Hornady 178 BTHP load
I just ordered another 2 cases to see if anything has changed. If they don't pop primers this stuff would fly off the shelves.

Re: New Hornady 178 BTHP load
Perfect timing on the bullets. Down to my last 100 and could not decide what to order. Now I know. Now to find who can get them and when!

Re: New Hornady 178 BTHP load
I ordered 500 from Grafs and Sons. I called to ask after seeing that Hornady announced the bullet. The nice lady said they had just got them in stock. I said " I don't believe you, you sure you heard me, that's the new 178 bthp." She confirmed and finished my order. Should be here in a couple of days. Can't wait.

Re: New Hornady 178 BTHP load
I even checked the SKU #. 30715 for the new 178 on my order confirmation. Buddy of mine ordered some as well.
Thank you Hornady for getting these out to market.

Re: New Hornady 178 BTHP load
I know it's not the 178 gr .308 version, but this seemed like a reasonable home for this info. So to anyone interested in the 5.56 version, I tested some of the Hornady 5.56 75gr BTHP Superformance side-by-side with their standard 75gr BTHP.
<span style="text-decoration: underline">Comparison of Hornady 75 gr BTHP Regular and Superformance Ammunition</span>
Equipment
1) Sig 556 Classic SWAT (16" barrel, 1 in 7" twist), Nightforce 1-4x24 NXS, Harris bipod/LaRue QD mount, rear bag
2) Sig 556 DMR (21" barrel, 1 in 10" twist), Nightforce 3.5-15x50 NXS, Harris bipod/LaRue QD mount, Accushot Monopod (rear)
Conditions
Temp = 60-65 °F, Wind = 2-4 mph from 8:00 direction, Humidity = 49%, Bar. Pressure = 29.90 S
Testing
Muzzle velocities were compared for Hornady 75gr BTHP Regular (2790 fps factory muzzle velocity) and Superformance (2920 fps factory muzzle velocity) loads by measuring at 10' from the muzzle, 2 x 10-shots strings for each ammo in each weapon, using a Chrony Beta chronograph. Final averages are the mean of the two 10-shot strings for each ammo through each weapon. Accuracy was determined from 4 x 5-shot groups.
<span style="text-decoration: underline">Results:</span>
<span style="font-weight: bold">Table I - 556 SWAT</span>
Superformance = 326 fps faster (avg.) in a 16", 1 in 7" twist barrel
<span style="font-weight: bold">Table II - 556 DMR</span>
Superformance = 216 fps faster (avg.) in a 21", 1 in 10" twist barrel
<span style="font-weight: bold">Table III - Accuracy (100 yd)</span>
During these tests, the ammunition performed flawlessly and there were NO misfeeds or cycling issues whatsoever. This was not surprising as both the SWAT and the DMR have the longer piston system. I have no information as to how the Superformance 5.56 75gr would cycle in the short piston setup of my 556 pistols (or a 5.56 Patrol, which also has the short piston). After reading Hornady's info regarding piston length, I decided not to run the Superformance through the 556 pistols, mainly due to the possible cycling issues, but also because I don't really see the benefit of using Superformance ammo in a platform I don't intend to use past 50m or so. NO overpressure signs (popped primers, discoloration) were observed in 100 rounds fired. The increase in MV of the 75 gr Superformance compared to Hornady's regular 75 gr BTHP was even higher in a 16" barrel (326 fps) than in a 21" barrel (216 fps).
Overall, the accuracy was about what I expected. I should note that I was only using a 4X scope for the 556 SWAT, and the DMR has never been very accurate with 75 gr BTHP loads from other manufacturers. For some reason, the DMR doesn't seem to care for the 75 gr bullet, regardless of who makes it or what powder is pushing it. In comparison, I can routinely achieve at or slightly below 1.0 MOA with either Black Hills or Federal GMM 77 gr BTHP loads. I suspect that a rifle that really likes 75 gr BTHPs will do much better with this ammunition. Notably, the accuracy did not differ significantly between the Regular and Superformance as shown in Table III. However, it is possible that the increased muzzle velocity of the Superformance might improve accuracy at greater distances as compared to the Regular 75 gr. An increase of 200-300 fps in muzzle velocity is pretty significant for a 75 gr load, and these bullets were coming out of the 21" DMR at very close to 3000 fps. In the future, I will try to see how the Superformance stacks up at 400 yd and over.

Re: New Hornady 178 BTHP load
i got to shoot the new lot number they replaced my 200 rounds originally.
This stuff shot .5 inch group at 100 yards the first time. Then about 1.2 inches the 2nd 5 round group im my harbinger bolt gun.
two primers had black rings around the primer.

Re: New Hornady 178 BTHP load
Ok, quick report. Got 500 178 bthp's in and loaded some up for my 20" AI AE. First batch: Hornady brass, 45 grains of Varget... Too hot (same load I had used for smk, Nos CC, 178 AMAX), 2.90 oal (touching lands). Had ejector mark, flat primer and slightly sticky bolt. They were cooking at 2780 from 20" barrel.
Backed down to 44 grains, 2.86 oal. No pressure and very accurate. Going to load more up and start seeing how they do at distance... Did not chrono this load yet. Guessing 2650.

Re: New Hornady 178 BTHP load
froggy how were you getting such high velocities with only 45 grains?

Re: New Hornady 178 BTHP load
Well I am not sure how to answer. Just the way that combo worked out. More bearing surface? More pressure touching the lands? Fast barrel? It was definitely a hot load for my rifle.

Re: New Hornady 178 BTHP load
I shot seven rounds of lot 3100547 out of a custom bolt gun recently. Of the seven, four had gas leakage around the primer, and one blew a primer. The case head actually swaged itself into the bolt face and had to be pried out.
Called Hornady and they were very nice, but the gentlemen was quite surprised to hear of the problem.

Re: New Hornady 178 BTHP load
I ran 10 rounds out of a stock 26 inch barreled Remington varmint rifle. Crono was measured at 10ft from the end of the barrel an got 2775fps without any pressure sign at all. the ES was 31fps an SD was 9fps. My 178 Amax load runs 2706fps average with an ES of 9fps an a SD of 3.2fps. (Use CCI 250 primers and their good for an extra 50fps average in a .308.) I did buy 2 more boxes of the 178 SP Match ammo to do more testing at distance with. But by this one test, I think I'll be sticking with my hand loads. If I didn't reload, I'd be all over this ammo. Plus I'll have 60 rounds of Hornady match brass to play with an put through the ringer. Overall I have no complaints with this ammo.

Re: New Hornady 178 BTHP load
Just sharing my new results:
I fired 90 rounds out of a new Lot#3101750. It is still doing some high and low stringing. Out of new AIAX 20" Bartlien it was 8.9 mils (50 degrees at sea level) to 960 yards and will consistently hold MOA. I tried no your limits drill at 600 yards several times. I printed several groups at distance on steel that were 3/4 moa though. I could never get it to shoot 1/2 or sub 1/2 moa at 100 yards or further. I only got one primer that showed bleeding after about 30 rounds, but I have been shooting in 40 degrees cooler weather than before.
I shot 5 shots of Lapua 167 scenars for a base and the gun will shoot sub 1/2 inch at 100 yards and smoked the 2 5/8 inch plate at 600 yards.

Re: New Hornady 178 BTHP load
Thanks. That is somewhat below the advertised G1. Still better than most of the other 175-178's.

Re: New Hornady 178 BTHP load
If you compare it to the Litz tested numbers on the 175 SMK, which is an actual tested G1 of .475, the Hornady 178 BTHP number above is still 27 points above the 175 SMK, which comes with a factory supplied BC of .496.
Also when you get to handle some of the new 178s you will notice the tips are much more consistent than the SMKs. This is due to the new bullet making process. I just got 2800 of them in yesterday and can't wait to load them up.

Re: New Hornady 178 BTHP load
I have a box of them to try. They're a nice looking bullet. I was really hoping that they would actually have a BC higher than the Berger BT Long Range though, since they're cheaper.

Re: New Hornady 178 BTHP load
From my short testing with some pulled superformance 178 bullets it's looking like 44grns of Varget in Hornady cases with the bullet loaded .020" off the lands is the load in my rifle.

Re: New Hornady 178 BTHP load
The saga continues, I really wanted to like this, but its not looking good yet.
10 rounds through an AIAE 20" Kreiger with a suppressor.
45 degrees, slow fire, batch number 3101733.
Three of the primers actually fell out (one stuck on the firing pin).
I am thinking the brass has issues with the pressure and is pushing the primers loose.

Re: New Hornady 178 BTHP load
Okay, now I'm convinced that if Hornady really is correct on the loads really being within pressure specs, then their brass is TOO SOFT!!!!!
So, anyone wanting to fund some original research, I'd like to conduct it in a scientifically rigorous and repeatable and legally-defensible way (Hornady might want to underwrite this for defense evidence if anyone sues for a $40 eroded firing pin or $200 or whatever bolt face...???):
1. Ship me 100 rounds of the Superformance stuff.
2. I will chrono 10 in a known-accurate rifle, and get velocities and fired case capacity. Then resize for sized capacity (see below)
break down 50 and re-load the powder and bullet in new cases as follows:
either:
a. in cases that come reasonably close to what the Hornady brass capacity is. IME, they are roomy and Winchester or something else "thin" would be needed;
or
b. in super-high quality cases like new Lapua, with some QuickLOAD estimates based on adjusting data from the 10 fired cases, firing three sets of three to verify, and then...
loading 45 rounds that near-duplicate the velocity of the factory stuff.
If the Hornady brass leaks like so many have posted but the other brass doesn't, then we knock Hornady for putting safe loads in soft brass. Federal will be replaced as the "crap" brass producer as far as case head hardness.
If BOTH brass leak at the primer, then I would conclude that the loads might not really be safe after all, *in some rifles*. That could simply be a matter of better process controls or maybe just not trying to be another Cor-Bon speed queen of ammo.
The pressure curve of that powder tells me that dropping the load by 25 FPS would still leave the loads as FAST ENOUGH to be noticeably superior for speed-freak shooters.
I'll do it just like any respectable scientific journal would.

Re: New Hornady 178 BTHP load
got the the range over the weekend FINALLY. Shooting the replacement 178 ammo. i was averaging 2895 out of my bolt gun, i have no idea what the original ammo shot, but i would have loved to compared. but sadly i didn't own a chrony then. My barrel is 24" Broughton. 1/10 twist bbl.
it shot extremely accurate, it shot better than any of the other ammo i tried that day.

Also when you get to handle some of the new 178s you will notice the tips are much more consistent than the SMKs. This is due to the new bullet making process. I just got 2800 of them in yesterday and can't wait to load them up. </div></div>
Definitely the truth. I go to the trouble of uniforming the meplats on all my loaded ammo. I got a case of Superperformance and the tips were uniform out of the box... all I was going to do was shave off BC by trimming them.

Looking at the new calibers in Bryans "Second addition" the Hornady 178gr BTHP is in there. I'm interested in the JLK 175gr also with a claimed G1 BC of .545.

10 rounds through an AIAE 20" Kreiger with a suppressor.
45 degrees, slow fire, batch number 3101733.
Looks just like mine last summer, except, yours are the sealed primers as the look of it. Guess there still isn't a fix. I stopped shooting it after Hornady replaced my batch. They were great on keeping me informed of the issue, and customer service was outstanding. I just choose to not shoot it anymore.
Three of the primers actually fell out (one stuck on the firing pin).
I am thinking the brass has issues with the pressure and is pushing the primers loose.

Re: New Hornady 178 BTHP load
Hello,
any updates on the Hornady 178 gr Superformance ammo in .308?
I am looking for stocking ammo that could potentially replace Lapua factory ammunition I am currently using, but from what I am reading Hornady is very controversial in their quality...
I shoot Tikka T3 Varmint 26inch Barrel and so far my best groups were with Lapua and Sellier and Bellot factory ammo.
The 168gr Hornady did not performe as expected from my barrel this summer.
Although no signs of overpressure the spread on 100 meters was about 34mm which is unacceptable IMHO...
Please provide more details on your recent experience with 178tn Superformance as I have to buy fair amount of quantity of factory ammo and need to decide whether it may be Hornady or to stick with my Lapua, although little bit more expensive.
Thanks,
A.
