Hi,

Can you maybe assist in the minimum and maximum loads for my 30 06 (24" CZ550 Lux)?Using S365 powder, magnum primers and Nosler 150gr ballistic tip bullets.

Your assistance will be greatly appreciated.

Thank you,

Best regards,
Anthony

Anthony,

Try 61.3 grains (3.972 grams) of S365 for a maximum charge.

Code:
Cartridge          : .30-06 Spring.  (SAAMI)
Bullet             : .308, 150, Nosler BalTip 30150
Useable Case Capaci: 60.345 grain H2O = 3.918 cm³
Cartridge O.A.L. L6: 3.340 inch = 84.84 mm
Barrel Length      : 24.0 inch = 609.6 mm
Powder             : Somchem S365

Predicted data by increasing and decreasing the given charge,
incremented in steps of 1.0% of nominal charge.
CAUTION: Figures exceed maximum and minimum recommended loads !

For a minimum, I'd back off 5% to 58.3 grains (3.778 grams) of S365.

Welcome aboard. Glad to have your question. Few of us this side of the pond use Somchem powders. They aren't generally available. Where do you live? Give us a little background about what you hunt and other rifles you may use. Again, welcome aboard.

Hi Dr. Mike,

I'm from South Africa, Mpumalanga region. I use my maat 30 06 for all my hunting. I mostly hunt blesbuck, springbuck, impala, blue and black wildebeest, gemsbuck(oryx) and kudu. Still deciding on purchasing a smaller and larger caliber rifle. I also have a .22 which I used to shoot some springbuck and blesbuck as well.

I think looking at the situation with Denel I believe Somchem powders will be more scarce to acquire. I live in the country were it is produced and it's even a battle for us to get it. Most SA reloaders are moving over to imported powders.

That being the case, here are some other options for you to consider if you need to do so.

Code:
Cartridge          : .30-06 Spring.  (SAAMI)
Bullet             : .308, 150, Nosler BalTip 30150
Useable Case Capaci: 60.345 grain H2O = 3.918 cm³
Cartridge O.A.L. L6: 3.340 inch = 84.84 mm
Barrel Length      : 24.0 inch = 609.6 mm

Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 59250 psi, or 408 MPa
or a maximum loading ratio or filling of 112 %
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 !

2 loads produced a Loading Ratio below user-defined minimum of 90%. These powders have been skipped.

Thanks JD. I had to ask the clever guys as I couldn't find any reloading data on Nosler points with somchem powder and this was my last resort. Somchem's load data only shows data for 150gr SPEER SP and on 150gr BT Barnes "X".
