Getting ready to load some 160gr NPT's for a 7x57 with open sights. Will start with mid-range load and stop moving up as soon as I hit something that is accurate for me. Curious. What powder goes with 7x57, like H4831 goes with 270, and RL15 goes with 375H&H? Paper punching and woods walking for KY WT's...

I use IMR 4350 in my 7x57 with 160 NP's.

Both IMR4350 and H4350 work very well--as does the "new" IMR equivalent, 4451.
H4831 (especially short-cut) and Ramshot Hunter work too, but in general I've had better luck with the first three powders.

Mine liked H4350 the best with IMR 4350 and H414 running second.

OK, Then.... I have a can of I-4350 sitting on the shelf from another project. Will start off with 40-42 grains and see where we end up... Thank you !

I'll be following this one.
Another 7x57 recently came into my hands, passed-down through the family. The loads were written on the side of the ammo boxes, then crossed out with a single line when it was time for each reload.
160 Nosler, 48, and 4831 were written quite a few times.

Powder is hard to come by right now, but I have seen 4451 on the shelf at a few different stores.

I don't wanna hijack the thread (too much), so I'll PM the gun pics. However, here's the historical data. It appears that they did employ 4350 in some instances, but still @ 48 grains. No recipe on the 145 grain bullet. I also found the cartridge shorthand to be intriguing: The cartridge people seemed to be OK with that; FC

Although I am big on using 3031 in the 7 mm Mauser..
I'll concede, you can't go wrong with 4198 or H 1000 with it and the heavier bullets..
with neither powder can you exceed, much less get near, SAAMI max specs for a decent American major manufacturer action...

Interesting thread. I have a box of Remington brass from years back, new brass never loaded. Headstamp RP 7MM.
To answer the OP's question, I've been doing a bit of work in the 7x57 with RL17 getting good velocity and very good accuracy in a Winchester M70 Featherweight. Been getting over 2800 FPS with the 150 gr. Nosler partition. but will be working with the 160 gr. Speer Hot Core spitzer and 170 gr. Sierra round nose shortly. Powder will be RL17. Paul B.

What's a reasonable max velocity with 160's out of a 22" barrel in a modern rifle?

In mine I use norma URP in all bullet weights from 140 to 160-162 grains with very good results.
With 120gr bullets, Varget is the winner.

Guessing thats a typo 4198 will get you well over max. 3031 might get you over it too. I'd run h4350 with 160s. H is the best 4350. Temp stable and meters the best. Very consistent results with low SD being common. H 4350 is one of the powders id have a hard time going without. Bb
