7x57 Mauser
I am looking for some suggested loads for the 7x57 using the Hornady 154gr. round nose. Ugly bullet but very effective on whitetails. I have some loads passed down by another 7x57 shooter but feel they might be a bit hot. (52grs. H-414 using the 154gr. Hornady)

Labman,
What kind of rifle are you using? This is important with this cartridge. Ku-dude

Well I use this very bullet out of mine and seated to the cannelure it ain't ugly!

Remington brass, remington 9.5primers, COL 3"
49gr Vihtavuori N160 MV 2650fps near max. Accurate but dark o'clock muzzle flash

As above but 42.5gr Vihtavuori N150 MV 2630fps. Reduced 0.5gr from max load in my rifle. Accurate and no dark o'clock muzzle flash.

Very very good bullet.

That load does seem "warm". I use 50 grains of H414 with the 140 grain ballistic tip.

I use 50.0 grains of either H-414 or W-760, with the Hornady 154 gr bullet. Great accuracy, and very effective load. Depending on your gun, I would still work up slowly to it. I truly enjoy the 7x57.

I just got your email. Your rifle is a strong action and can handle this load. This is close to a maximum load. 48grs of IMR4350, WW Large Rifle Primer, and 150 Rem PSP. This worked quite well in my M77 which also had a long throat. Ku-dude

I( have never used the Horn. 154 grain, but in my Ruger No. 1A 7X57, I have used several loads with the 160 Nosler Partition that develop over 2800 FPS. These use slow powders, beginning with IMR 4350 and including MRP and Re 22. I can't seem to get enough Re 22 into the 7X57 case to even generate max. pressure signs, even when using 175-grain bullets!! But my gun has a very long throat!!

I've loaded 53.7 H414 in my Ruger 77 with 140 Nosler partitions for 3038 fps on my chrono. My rifle has a long throat and this load is perfectly safe,but be careful. The 52 grain H414 load with the 154 would probably work in mine. I hunt with some friends with 7mm Mags whose factory loads were slower than this.

And I get 3100fps with 139gr Hornady factory loads in my 22" barreled .280 Mountain Rifle.

Does anybody know the weight of the bullet in the military 7x57 round? I have a Brazilian 7x57 and would like to construct a load that duplicates the origional one.

Thanks

I have a few DWM militairy rounds, made around WW:1. I took one apart, the bullets weight is 173 grains roundnose style bullet.

The bullet is magnetic soo I guess it's steel jacket, true kosher for the barrel [Eek!]
The primer is an old mercury that will rust line the barrel [Eek!]

Brazil and Columbia used 139gr bullets @2950fps, Uraguay 142 @ 2740, Mexico 155s & 162s @2300. Original Spanish loading 173 @2296. This according to Cartridges of the World, Third Edition. Hope this helps.
