Home Forums Reloading Big Game Rifles 7 x 57 mm loads

I use H-414 with bullets up to 154.

RL-19 for any thing heavier.

Thank you Poobah,you taught me well. The a** chewin' you gave me is now healed over.

My go to load in my 7x57 is the Sierra 160 gr BTHP with H4831SC. I don't like any bullets under 160 gr in the 7mm's . The 7mm is at it best with 160 gr or heavier regardless of the case you use to push it . .

The only powder my Rugers responded to was a charge of 40 grains of 3031, regardless of bullet weight... my favorite two bullets with those rifles were 154 grain and 175 grain Hornady RNs...

I also have a Model 70 Featherweight in 7mm Mauser...

it will shoot anything I feed it and shoot groups like it thinks it is a varmint rifle...

Got an old DWM Mauser that thinks the same way. LOL

I 'borrowed' INGWE's load using H4831SC and Barnes 160 TSX to use in my SC M70 7x57 Fwt. It's a tad 'warm' when shot in 90*/90% humidity, but it's accurate! Waiting to see how it shoots when the temps and humidity drop.

now why would ya'll want to put up with the extra recoil and loopy trajectories with those heavy boolets?

(stirring the pot a little)

All I've ever done with mine is hunt whitetails, and for that the 140 at about 2700 fps seems about right.

A 140 gr bullet,dude your gonna "smoke a turd in hell" for shooting a 140 gr bullet.

No loops in a 175 going 2700, just four hooves pointing North.

The fastest I can get with my 7mm Mauser's is 2600+ fps with 175's.

Just helpin' you stir the pot.

I'm (partially ) serious, to me the 7x57 is all about a 139 g Hornady SP movin at 2600-2700 fps. I've had good results with the regular ol' anemic remington green box load too

I'm new to the 7mm Mauser,all I have done is punch paper and shot 1 Jackrabbit.

The 2-7x57's I own:

Got this one in June 2013. Winchester M 70 Featherweight with a Leupold 6x.


Bought this one in January 2013, CZ 550 American with a Zeiss 4x on it.

n8dawg6 I have to sort of agree with you. I have had 3 7x57's in the past and yours sounds about like the speeds and for that weight I experienced . With the heavier bullets I was a couple of hundered FPS less than that. I have always been a little leery of some of the claims I see made about the 7x57 and 7mm08 especially when you compare them to 280 remington loads with it's larger case. I'm not knocking the round as I see a 140 gr bullet at 2700fps as very deadly on game as well as a 175 gr at 2500. Obviously some have done well loading faster than this for some time but I guess I'm just too big of a chicken with pressure to try it. I'd just as soon go to a bigger case.

40 grains of 3031 out of an older Hornady manual, gives me 2640 fps out of a 22 inch Ruger factory barrel...

52 grains of H-4831 and a 175 gr Rem is getting 2625 fps average out of my Featherweight which has a 22" barrel. Funny thing is out of my CZ,it's 2590 fps with the same load and the CZ has a 24" barrel.

Guess I have a fast 24" barrel, it will reach 2700+ fps with IMR or H-4350 and either the 175 gr Speer GS's or NPT's.

I love that old Mauser, would be a bit to heavy for most folk at around 9.25lbs all up.

Gunner

Schit,that CZ I have is 9 lbs as is in the pic. The Featherweight is 7 lbs 14 oz as is in the pic.

Well Gunner500 those 2 rifles are going to Arizona in November for a bear hunt.

That'll work Main, good luck on the hunt.

Handed that old Mauser to a Bud one day, he exclaimed, damn, I wouldn't have that heavy sombitch, I said, you have put 100 lbs on yer ass and another hundred on yer gut since school and you bitch about my 10 lb rifle?

He didn't find any humor in my reply.
