7x57mm Mauser Recoil data and Ballistics 140gr

[bullet]

Not shabby at all and with half the recoil of my 300Win mag with a 165gr bullet which is 31.7 ft-lb of free recoil and is only -9.7 inch at 350 yards when sighted in at 2.7" high at 100yds. I think I will be spoiled with this 7x57 Mauser. The following is what I will be shooting for when I get my new rifle.

Looks pretty nice Mike. Those medium capacity 7mm's are pretty surprising. I have never owned one of them. I would love to have a 7x57, 7-08 or 280. Something in that range would be a nice rifle. I know I love my 7WSM. It just shoots well and and has minimal recoil for the speed it is putting the bullet downrange. Scotty

Just curious where you got the load data. I haven't seen anything over 2900 fps for 140's in all the places I look and I'm doing load development for a modern 7x57 too. Wish they'd start calling it "7x57 +P" like they do with the Bob and some of the others. Do you have some MRP stashed or a secret supply? Keep us posted when you get development going. I think you might like H414 also.

Quick load is my tool for load data, and it has been so on spot for so many cartridges I have loaded and POP has been my source for the data. You can get MRP from Grafs and Sons at times and some other places. I usually buy 2 pounds at a time and I have stocked some away that are the same lot. Yes, on the H414, it is a good on for the 7x57 Mauser. I do a great deal of research before I begin load work, reading everything I can get my hands on and it pays off saving me lots of time, effort and especially money.

Mike, I've read enough of your posts to know you weren't fooling around. I'll keep looking for the MRP, Graf's is out right now. Is it true that it's nearly the same as RL22? I know the 7x57 is underloaded in nearly all the data and why. Always found it curious that with a h2o capacity of 60 grains, why more powder/bullet combos haven't been published that take advantage of that. A guy has to dig into Ken Water's writings and places like that to find most "modern" loads. Anxious to see the rifle and the results!

btw, my first 7x57 was on a Mauser98 action, Douglas barrel. I was shooting 130 gr. bullets with 46 gr. of IMR 4320. No idea what the fps was, but trajectory was good and time of flight to 300 seemed way quick enough. This was with brass formed from LC52 '06 surplus. I think it might have had thicker than average walls.

Mike,

The 7x57 is right on the heals of the great 280 Remington.
The 140 gr PT is a pretty amazing bullet and is perfect for the 7mm Mauser.

It will be interesting to see what happens. I might not be able to meet my expectations but it will be fun trying.

Yes, the 7x57mm and the 140gr bullet are a match for sure.

What is the OAL for that load? What bullet? I have a 7mm ackley that I am still working on loads
for.

 

[clearwater]

Is this on a short or long action? Bullet seating depth sure plays a factor.

quickload for 7x57 AI with reloder 17. Maxes at 2810 fps.

be interesting to see how the standard version 7x57 compares.

Yes, when I finally get it we certainly will see.

You guys have me all stirred up. I bought a 2nd hand Encore rifle barrel made by MGM today, ordered 40 pieces of Norma brass, will buy the 140 partitions and powder when I get back to VA from Uruguay. I had 12 Axis Deer swim across the river and take of residence on my ranch. Two are nice bucks. I think the 7X57 and those 140 PT's will be just the ticket. :grin:

Yes, that sounds like a great combination indeed.

Yes, it is too bad that data for proper loads for the 7x57 in modern rifles is not available. Same thing with the 30-06. I'd almost be willing to bet that the guys who work in the labs making the load data have proper full power" load data for their 7x57 and 30-06 rifles. All we can do is work up carefully and try and be safe while doing so. I like W760 (same as H414) in my 7x57 rifle.
Someone mentioned the similarity between MRP and RL22. from what I've read eslewhere, they are the same powder. As usual, just work up carefully.

Yep been here before with all my 06's, I know how to be careful and work up my loads, and I have over the years never been able to get the same results out of the same rifles, with the same load chains and same charges of powder with MRP or RL-22, never! Ouick Load never has them the same in near max charges either with same bullets. I have tried them both in 7mmSTW, 7mm Mag, 30-06 (heavy for caliberloads) 338Win, 340 Wby and 416 Wby with many loads and they never work the same although similar in burn rate I do not believe they are the same. I have read all kinds of reports on them, and read lots of opinions on them in theory, but my empirical evidence of constantly comparing them has never had these two powders ever act the same in pressure signs, velocities or accuracy. In fact I was hoping they would be the same because it is easier to get RL-22 but I am here to tell you they are not. My last case in point using my Savage 300Win Mag with the same charge of powder, same 180gr TTSX, same brass, same primer, same OAL same rifle and I was able make one hole ragged hole with the MRP and the RL-22 was no where close.

Mike, I was able to find a gun store close by that sells Norma MRP, URP, 204 etc.. Might give it a whirl. Scotty

If you get some, get with me on load and charges.

 

[SJB358]

Will do Mike. It is a couple of bucks more per pound, but I wouldn't mind trying it in something if it runs like RL22. Honestly, I could do alot of shooting with RL22 in just about 50% of my rifles. Scotty

I can't put my finger on it but when it comes to velocity and consistency once a load is found, I find it a better choice than RL-22 for me, notice I said for me, as it has worked out for me.

I totally understand that Mike. I am always on the search for better stuff. RL22 happens to be it right now. Retumbo is pretty good in the 264WM for speed and accuracy. I am not against using what is best for the cartridge. I figure someday I will stock up on 5-8lb jugs of some of them, but so far, 1lb'ers last me quite awhile. Scotty
