140AB 7mm Mauser 2940FPS

sjb358,

The maximum velocity for the 7-57 in Hornady's new manual is 2700 fps.

Those loads are in 1930 pressure maximums. A modern 60KPSI action will safely reach those velocities that Scotty is getting.

Thank you Savage 99 for looking up that data. I have a couple Hornady manuals as well, but I am shooting Nosler 140's. So all of my data has been researched and built using Nosler manuals and QL software.

And Charlie nailed it..

The maximum load in Nosler #6 shows 2892 fps.

Maybe you have 130 gr bullets?

The 7mm WSM will do 3295 with 140's.

In a moder action with modern brass you can go side by side with the 270 65K psi MAX

Yeah and I think if 3100-ish is do-able in the 270 Win with 140 grainers, then 3000fps would not be absurd in the 7x57 with a modern action rated at the same specs.

Lets face it; Hornady does a 139g load for the 7-08 at 2950fps and it has less case capacity than the 7-08.


I might add I am not a fan of driving loads into the red-hot zone, but a 7x57 deserves to be loaded to the potential of the rifle it resides in I think.

Yeah, maybe they are 130's.. I probably just overlooked it. :roll:

Thank you for the info on the 7mm WSM. Never heard of it. Sounds pretty good though..

Glad we cleared that up!

Here is a 140 AB pulled from the backstop at my 200 yard target.. Still looks pretty decent after smashing alot of rock and dirt..

Very impressive, Scotty; very impressive, indeed. That would put a lot of punch into any game. In my old 280, that is one of the bullets I've gravitated to for deer and elk.

 

[sask boy]

Scotty thank you for that bullet test with photos. There is not a lot you can say when a bullet performs like that :wink:!

Blessings,
Dan

Just for kicks try some IMR 4350 in the old 7X57 if you happen to have any sitting around.
I bought my wife a Ruger M77 in 7X57 about 30 years ago. For hunting I loaded with 140 Gr. PT's, a very good bullet in that chambering.
I use to have at least half a dozen rifle powders on the shelf all the time but now I only have IMR 4350 and the results with the 7X57 is what made me rethink the powder thing. I have used it in .22-250, .243, 7X57, 7mag and .300 Win. It is a really versatile powder.
Of course that was before all these new powders have come out. But it remains a good choice.
Wish we still had that M77 but I let her sell it when she quit hunting. If it had been left handed we'd still have it.
