QL request for 7x57mauser

[michaelcj]

I am primarily interested in pressures.

My rifle is a late 1903A3 action with a Douglas Premium 24" Bbl 9.5 twist. [Throat is 2.85"]

Using IMR4350 exclusively with Nosler Partitions in 140gr / 160gr. Remington CorLock in 150gr.

RP Brass : my electronic scale only weighs in "full grams" but converted suggests 61.73 grains H2O volume. [may need a better scale]

Winchester LR primers

COAL on all 3.07

Thanks
Mike

Michael, undoubtedly someone will be along shortly to assist. Unfortunately, I'm away from my copy of QL. However, I do want to welcome you aboard. We're always pleased to see new people joining us on the forum. The 140 grain PT works very well in the classic 7X57. I've worked up the load for a couple of rifles. It will definitely take down as moose, and anything smaller.

The data for the Remington bullet may be a little off from what QL should output. It seems that the database for the Remington bullets is incomplete and I had to enter a bullet length manually. I used 1.15 inch. It should not make a lot of difference.

 

[michaelcj]

Thanks River Rider!
Interesting when compared to "Max" in the Nosler manual [#3].

I'm not at all interested in trying to make a "magnum" out of this, but would like to experiment near the "european" loads as compared to the SAAMI.

Looks like I'm going to be okay without approaching the max for the 03A3 action as I will stay under 52200psi [closer to the 48000 to 50000psi range]. Should leave me plenty of margin.

I am up to 1grain below the max target with no pressure signs with the loads I've tested so far, VG accuracy.

Thanks again
Mike

I might consider a different powder. I'm matching the 140 and 150 listings, out of my 7mm08, with a 22" tube. Same brass, same primer.

 

[SJB358]

RL17 is magnificent in my 7x57. 2950 for 140's and 2890 for the 150 BTs. Haven't worn out a case yet. May take a little tweaking on seating depth but it works very well for me.

 

[RiverRider]

I think Scotty's onto something. Relying on QuickLOAD, of course, Re17 is one of those powders that can operate in the 7x57 at 50000 psi and still be completely burned. Not that there's anything terribly wrong with 99% burn, but there are powder choices that won't get anywhere near 100% burn when pressure's held down to 50 kpsi. Keeping in mind the progressive burn principle, which would you expect to yield the most consistent velocities, a powder that burns 100% or one that burns 92.5%?

Check out these results:

[RiverRider]

In the results above, I allowed a pressure of 62000 psi. Note which powders, and how many there are, that give a 100% burn.

Now I'll hold the pressure limit down to 45000 psi. Note the differences.

Cartridge          : 7 x 57 mm Mauser
Bullet             : .284, 150, Remington PSP CoreLokt
Useable Case Capaci: 54.286 grain H2O = 3.525 cm³
Cartridge O.A.L. L6: 3.071 inch = 78.00 mm
Barrel Length      : 24.0 inch = 609.6 mm

Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 45000 psi, or 310 MPa
or a maximum loading ratio or filling of 116 %
These calculations refer to your specified settings in QuickLOAD 'Cartridge Dimensions' window.
C A U T I O N : any load listed can result in a powder charge that falls below minimum suggested
loads or exceeds maximum suggested loads as presented in current handloading manuals. Understand
that all of the listed powders can be unsuitable for the given combination of cartridge, bullet
and gun. Actual load order can vary, depending upon lot-to-lot powder and component variations.
