240 weatherby/ reloading

[paolo65]

And here I am, asking for your help.
I recently bought a weatherby ultralight in 240 cal, I put on it a Zeiss 3-10x50 diavari and I started with the factory loads for Norma with 100 gr Partition. Good result, but not good enough for a reloader (crazy people ). The problem is that in any reloading manual for this caliber I find mostly US powders that in Italy we are not able to find except sometimes IMr (not the whole production!!!) and I am obliged to work with vihtavuori or norma. I would reload Partition 100 gr. can you help me with some suggestions? my first target is accuracy of course
thanks,
paolo
ps: when will be on the market a 6mm AccuBond 100gr ???

Here are some. These are 1000 psi under max so be careful.

Cartridge : .240 Weath. Mag.
Bullet : .243, 100, Nosler PART SP 35642
Cartridge O.A.L. L6: 3.100 inch or 78.74 mm
Barrel Length : 22.0 inch or 558.8 mm

Predicted Data for Indicated Charges of the Following Powders.

Matching Maximum Pressure: 62000 psi, or 427 MPa

or a maximum loading ratio or filling of 105 %

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 !

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

Thanks a lot Pop. :grin:
I'll try with vihtavuori and norma and keep you informed on the result.
By the way: do you like this caliber?

 

[FOTIS]

I love that caliber. Only played with it one time but something about a 100 grain Partition cruising at 3300+ fps!

"In bocca al lupo!!" Paolo

"crepi il lupo" and I'll keep you informed on my results with the reloading of 240 wea.
