Hi folks,

Would someone be kind enough to run quickload for me?

7x64
CIP / SAAMI specs
160gr TMK
Twist 1:8.25
26" barrel
FL Resized brass

I accept that I use any loads generated at my own risk

Thanks in advance,

Scrummy

I'm afraid Quickload V 3.9 does not list the Sierra 160 grain Tipped Match King. I don't see an update for V 3.9 either.

Really? Are you sure? That's a bummer!

Not listed under the TMK acronym is it?

It's interesting, I see TMK's in .308 and .264 but not in .277 or .284. The only listing for a .284 in 160 grains is SPBT and HPBT.

How odd. They definitely exist. I shot some on Friday and ordered some more yesterday...

Could I be cheeky and ask you to run the 160gr HPBT as it will give me a good idea of where to be looking?

It looks like there was a data update as of April 2020 that I don't have. Maybe someone else here can help you out. Smiler

I can run that info for you.

l'm sorry l came upon this too late Scrummy or l'd have run the numbers for you.

My 7x57lmp' really likes RS70 and has a relative case capacity, so as you are thinking it may very well be the place to begin your testing.

Hi there,

7x57 isn't exactly a common one! Much run very close to 284W I'm guessing?

Aye up Scrummy.

l've found through experience that my 7x57imp runs very close to 7x64 ballistically, and RS70 seems to be my "go to" for anything much above 140's.

l was looking at a set of 7x64 dies recently and thinking Hmm..... Both are great Plains Game rounds in their own right, but the 64 does have an edge over the 57 but not the improved, l just went that way for the hell of it at the time.

Ratty.

Its easy to duplicate the 7x64 with a 7x57 in a good Win. or Mauser with either CFE-223 or H414, and brass is much easier to come by..I shot the 7x64, 284, and .280 a good deal and finally settled on the 7x57 for the handloader for a number of reasons..much of which showed up on my chronographs..

I set for 55k PSI and 110% (compressed load):

Cartridge          : 7 x 64 Brenneke
Bullet             : .284, 160, Sierra TMK 7660
Useable Case Capaci: 59.495 grain H2O = 3.863 cm3
Cartridge O.A.L. L6: 3.307 inch = 84.00 mm
Barrel Length      : 26.0 inch = 660.4 mm

Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 55000 psi, or 379 MPa
or a maximum loading ratio or filling of 110 %
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.
USE ONLY FOR COMPARISON !

33 loads produced a Loading Ratio below user-defined minimum of 60%. These powders have been skipped.
