I have developed a load for my Rem 700 using 162gr Hornies and H1000. This is a good load and it has served me well.

I also have a bunch of 150 gr Partitions sitting around collecting dust that I would like to use. Problem is I loaded some according to the Nosler Manual but velocities were very unispiring. I barely got 3000 fps where Nosler claimed 3250 or so. (Now, I know every rifle is different but....)

I can beat this velocity with my current load but I can not beat the bullet performance!
What loads can you guys suggest?

Hey POP - so, YOU developed the 162 Hdy/H1000 load, huh?

Anyway, my deer hunting load is 64 AA3100, R-P case, R9-1/2M primer and the 150 Partition, for around 3,100 FPS and numerous sub 1" groups (100 yards) from both my 7RMags with 24" barrels. A similar amount of IMR 4831 gives a little better velocity, but the accuracy isn't quite the same.

No actually I developed the 80gr of H870 with the 162...in 1993.

I shall rephrase... I worked up to 72.5gr of H1000 in my rifle.

Did not mean to steal your thunder

Thanx for the 150 load!

Sorry guys--got home from the bowling alley tonight with beers on my breath. Every time I see h870 posted I have to laugh. The only 1#'dr I owned did about 300 fps slower than posted velocity and was dirty as hell and still somehow split magnum cased like butter. Must have been the dreaded "belt"!!! I burned what was left in a silly ceremony in my driveway. Didn't even leave a burn mark....I knnow I must have gotten a bad batch!!!!!!!!!!!!!!!!!!!!!! Time for bed----hope you guys cann laugh with me!!

Kraky:
How many times have I said this? No PUI's!
"No Posting under the influence!"

You're right though. I have seen huuuuuuuge variations in burning rate in different lot #'s in H870!

POP, I tried H1000 with 160gr Part. at 73 gr, norma brass and F215M primer(way over Max). I'm getting 2950 chrono'd. This is in a 24" bbl old (1977) Ruger M77. I'm thinking its time for a new bbl.I have had very good luck with 65.4gr IMR4831 with 154 Horn.when the rifle was new.Good luck

These are Max loads in my rifle start at least 10% below as a starting load

POP -

Just yanking your chain How'd it work at 72.5 grains? Never went that high.

Pop and others: H870 used to be my powder of choice in 7 MM Rem, and I used right at 80 Gr. This was in a Ruger M77 as well. The last batch I bought, the case won't even hold 80 Gr. I just used up the rest of it, and max load with a 154 Horn was 76 Gr. This was on the same Ruger but with a new Douglas barrel. I'll never buy H870 again. With the old lot of powder I had, I don't think you could reach a max load on the M77.

As for the 80 Gr. loading, I was using it in the early 80's, maybe late 70's.

r-west. The H1000 load (72.5gr) went 3080 or so with the 162gr Hornadies. Best group so far is 2" at 300 yds.

What ever happened to 7 mag ..150 gr..3250 fps?

I am not velocity happy, just could never realize that speed.

Pop,
I have an early Rem with a ss factory barrel. I bought this gun used but almost unfired. For the record the load I shoot is 69grs. of R22(CCI#250 primer) and a 150gr. Nosler for 3145fps. The same charge behind a 160gr. Nolser gives 3175fps. Primer pockets stay tight for aleast 6-8 reloads, and it shoots groups just under an inch.
I used to have a Ruger 77 in 7mag also and that rifle would only take loads of about 3grs. less and give just over 3000fps.
The loads I have given are just fine in my Rem. but my not be in other rifles. Anyway try some R22 powder. Pete

I dunno. I think a lot of it came from original pretty high pressure loadings and/or velocities in 26" or longer barrels (or advertising hype??).

Wasn't the original 160 grain loading supposed to be around 3,150, too? I know I've never gotten close to those numbers in my 24" barrels, that's for sure.

When the 7RMag came out in '62, not too many people had chrono's to check on the factory numbers. They've made some pretty drastic downward revisions over the years. Just checked the 2002 R-P ballistics chart: 150 Scirocco, Core-Lokt & B-Tip = 3,110 FPS; 160 A-Frame = 2,900 FPS; 160 Part. = 2,950 FPS.

That 162 H'dy/H1000 load at 3,080 with great accuracy and no pressure signs looks better all the time, doesn't it?

Ran some factory and handloaded 7mm Rem mags over the chronograph with the following results. Rifle is a 24" barrel Rem 700 ADL.

Rem factory 140@3225 fps
Fed factory 160@3098 fps (Federal Classic SP)

Sierra 175 SPBT, 78 gr H870 @ 2911 fps

The Rem 140's and the Federal 160's were both faster than advertised by the factories. Those 175 grain Sierras are remarkably accurate too. Regards, Guy

r-west...It is a great load. Just that the 162 Horny is not quite tough enough for elk....in case of a bad shot that is.

try IMR 7828 with the lighter bullets in the 7mag, it's been the best for me with 139 and 140s, fast and accurate

I really like the H1000 with 160s, and the H870 has worked well with 175s, though I've also noticed it's dirty
