Thumbcocker: I have used the WONDERFUL Nosler 160 grain Partition bullet in my handloads for many years now - it is accurate and lethal.
NO reason what so ever, to even consider changing.

That sounds like a load I'd like. Not too hot substantially fast and 150 grains of partition. Great bullet.

My rifle like 150's. It shoots the partitons and cor lokts in to little tiny groups. I'm going to try some 160 partitons also.

Try a few 160 NAB's while you're at it, see which one your rifle likes best. Terminal perormance pretty close.

See if SPS has some seconds or blems. To me, they shoot as good, cost less.

I have some accubonds. I;m going to try them also once the weather breaks for good.I have some 160 grain speer hot cors too.

Hot Cor’s have a good reputation and a loyal following.

I’d try all three, let the rifle pick the winner. Hard to go wrong.

I have used 150 grain hot cors for years in my 270. No complaints

Here in Utah I haven't seen many use a 175gr, most use 150-160 it seems. This is not a big survey, just casual, of course. There could be a 100 out there that do!

Jack O'Conner thought that the 150 killed elk better than the early 175, but the first 175s were sort of oddballs they were semi spitzers and I think loaded down as a sort of brush load. Remington did what some manufacturers were doing with the 270 150 RN. It didn't take long before the 175 CL was upgraded to a spitzer. I have had good results with bullets from 120 to 175 but now use 168s and 175s as I shoot the lighter bullets in the 280 AI.

I shoot 65-66g, Rem brass, 9 1/2 primer, bullet .005 off the lands.

accurate and very deadly

As a PS to my earlier post, several of my hunting buddies have switched to Barnes TTSX from whatever else they have been using. I’ve never offered firsthand advice since that sometimes goes sideways with friends and family. They’ve just seen how the catchy blue tips work. 😂

Tejano,

After recently starting some historical research on the 7mm Remington Magnum, I have started to suspect that part of the reason Remington loaded the 175-grain roundnose (not "semi spitzer") Corelokt in their original 175 factory load because they had a bunch of leftovers from when they made 7x57 ammo. By 1962, when the 7mm Magnum was introduced, they hadn't offered 7x57s for several years. So they used 'em up in the 7mm magnum ammo, which gave them time to develop the "pointed" 175 Corelokt.

They introduced the 175 PSP (Pointed Soft Point) load in 1965--and also upped the listed muzzle velocity from 3020 fps to 3070, because DuPont had developed IMR7828 (primarily for the 7mm magnum) which allowed a little more zip.

Of course, the advertised muzzle velocities for the original 150 and 175-grain loads were optimistic, because they were from 26" barrels, and except for special orders, the 700 rifles had 24" barrels.

Correction- my earlier reply....it was NOT 65gr BUT ACTUALLY "60 grains" of IMR 4350/160PT. I was able to get to 63gr/IMR 4350/150 Partition. I had a moment of "Clear Recall", ha. That particular rifle didn't like Norma MRP nor H870 ( it took me forever to find any back then) But it loved all things IMR 4350! So, don't try to use 65gr/IMR4350 with the 160PT! ha

180 Scenar with H1000, Retumbo or RL26. Doing 2850 to 3000 fps muzzle velocity. Very hard on living things.

I haven't played with H1000 in the 7Mag yet. How do your loads (charge weight and velocity) compare between H1000 and R26?

R26 is getting 125-150 fps more speed with accuracy vs H1000. Work up to the speed you want as the throat on mine is a touch longer than normal. Scenar seems to like being closer to the lands. Anything 2850 fps and faster with accuracy has been pretty awesome on game.

Thanks. PM sent. IMR7828ssc and R26 have both given good velocities with the 180 ELD, but I'd thought I'd try playing with H1000 a little.

Didn't know this and I was mixing up the original 175 Nosler semi spitzer with the RN CL.. Look forward to your article. Thanks.

How does speed and accuracy compare, 7828 vs R26 in that application?

In all my 7WSM and 7RM rifles, and with my particular lots of R26 and 7828ssc, they have been nearly identical. Velocities with like powder charges are within 10 fps, and accuracy is similar. I ended up sticking with 7828ssc because it's easier for me to find.
