I just recently purchased a Remington 700 5r millspec in .308 win. , and I plan on using the new Hornady superformance interbond 165gr catridge in it to hunt deer and hogs. So does anybody have any experince with this round, regarding velocity consistency and accuracy, and the terminal performance on deer?

Hornady lists that ammo as having a muzzle velocity at 2840 fps. I believe that should be adequate for most whitetail deer. They must be using that new Alliant powder, 2000MR. I'm using it in the .308 and I'm pushing a 150 grain bullet to 2950 fps with no danger signs. The load shows consistent Es and Sd.

I push a 165 grain bullet to 2810 in my .30-06 and it knocks them over fairly quickly. I suspect it's overkill for the smallish deer we see in our woods, but I don't have to do much tracking.
 
Yep, that's exactly why I plan on using it. It brings the 308 win up to the level of a 30-06! The only thing I am worried about is getting consistent velocity with this new powder. Seeing as though I don't have a chrony Has anyone taken a couple shot strings overone?
 
Not with the ammo, but with the powder. I've been testing a pound and so far I'm seeing that the Alliant claims are conservative. I'm pushing a 150 grain bullet past 2950 fps with good accuracy. However, I'm using pure hunting rifles, thin sporter barrels and my benchrest technique is purposely flawed. I shoot my rifles off my palm, just like I do when I'm hunting.

It looks like this new line of powder is going to be very interesting indeed.
 
I have been hunting with my .308 for 12 years now, my understanding with the hornady superformance brand ammo is that the powder being used is proprietary, but since your getting similar velocity with that powder , what length barrel are you using?

I've got two .308s. A Savage 11 and a Remington 700. Both have 22" barrels. Both of these rifles are sporter barrels, not specialized precision rifles. Plain-Jane hunting rifles. I've been playing with Alliant Power Pro 2000 MR in that cartridge. It's a spherical powder and the jug says that it's made in the USA. I suspect that it's made at St. Marks and is closely related to the Winchester brand of spherical powders. I've got a full write-up at my blog and I'm getting some really interesting velocities from that powder. All my recipes come straight from the Alliant website, and I haven't gotten to the max load yet, although I've toyed with it. What's interesting to me is that I'm pushing a 150 grain bullet past 2950 fps with no pressure signs. The primers are still nicely radiused with no primer cratering. The bolt lift is normal.

If you look at Hornady's website, they're claiming 3000 fps from the 150 grain SST Superformance. I'm using the same bullet and my best speed so far is 2971 fps, and I'm not at what Alliant calls a max load. My barrel is a 22" sporter barrel.

If you google around, you'll find other folks saying that they're getting better than 2700 fps with 180 grain bullets.

I haven't tried that powder with 165/168 grain bullets yet. I've got four pounds of Reloder 15 that gives me excellent accuracy and that's probably the load I'm going to use for hunting this year.

But, that Power Pro 2000 deserves another look.
 
The interbond bullets should be fine for the purposes you listed. Whether this ammo shoots accurately from your rifle will have to be tested.
 
I've tried the 150's in my 308's. Average velocity was 2962 fps in a 22" Winchester EW rifle. Accuracy is OK. Just a bit over or under 1". I can get better accuracy with my handloads, but I'm about 130 fps slower.
 
I shot the superformance 130gr sst's in my 270 win last year, and they grouped just as well as the federal premium ballistic tips. The sst bullet didn't hold together well on the doe I dropped at 100yds though. The noslers held together much better IMO, so I'm thinking of trying the interbonds this year myself. If they group well...
 
That's what I've heard, the sst bullets don't hold together good at close range. And the interbonds have extremely good weight retention. So if they group well, they should be near perfect for hunting hogs and deer!
 
I load the 165 gr Interbonds in my 300 WSM, and they are extremely accurate with more instant drops on deer and hogs than any other bullet I've used. The IB works very well at the WSM velocities, and stays intact at all distances.
 
May be a batch recall.

I shot the Superformance in .223. The first four cratered heavily, the fifth pierced. All rounds were high about 2 inches from my regular ammo. They didn't group worth mentioning. I was only shooting it because I wanted the brass. I had to refinish the pin and dismantle and clean the entire bolt.

The two boxes I bought are now back at the manufacturers being tested, as they asked for them back.

They get a big vote of no confidence from me. But I'll be interested in what they say.

A friend of mine had a similar issue with .270 Superformance rounds. We were out shooting and when he ejected the 3rd round, the primer was missing. Hornady sent him a call tag to send the ammo back.

Even with ear plugs and muffs on, they were still loud and my friend said they kicked like mule. He has no intention of shooting more of them. It's a none issue for me since I only shot my loads.

Maybe my experience with the Superformance is unusual but it has been superb in my Vanguard 270 Win. 130 and 140 grain SST have been very accurate and terminal performance has been perfect. All pass through and watch them drop in the scope. Lungs are liquid upon field dressing and these are Michigan deer so they are 100 lbs to 150 lbs dressed. I think Hornady products are top shelf.
 
I just picked up a box of the 165gr superformance interbond today, I had to direct order from the factory because my cabelas didn't even carry them yet. They sent me a whole crate of them!! And I only ordered one box! My good side got the better of me so I didn't take them.:eek: Haha any way I'll keep y'all posted how they shoot.
 
Well my remington 700 5r has a twist rate of 1:11.25 which is made for 175 grain bullets, so that's the main reason I went with the heavier bullets.
