Anyone have any they can share? Thanks...

not sure which 5.6x50 you're talking about, but if it happens to be the 5.6x50Rmag - you can use 224 weatherby data. the case capacity is almost identical. just use the usual precautions

It's the rimless version....rifle is an original Oregon Kimber...Thanks for the info....

woodhickie,

A Kimber in 5.6x50 Magnum would be a very nice rifle IMO.

A rifle so chambered is a pretty seldom occurance even here in The Fatherland; the Rimmed version is much more often encountered; mostly (like myself) in Insert barrels for Combo Rifles & Drillings.

I use the Rimmed version; 5.6x50R Magnum.

The somewhat larger capacity case tends work best when you take a step up from the quicker burning powders more normally used in the smaller volume .224" cartridges, .222 & 223 Remingtons into the medium burning powder range that offer better performance in the 22-250 Remington & 220 Swift sized cartridges and European data seems to bear this out too.

Since most .224" barrel twists here in Europe lend themselves to the standard 50-55 gr bullets for best accuracy that's where I put my efforts. I've tried the Nosler 60 gr. Partition, the Barnes 53 TSXs and the Speer 70 grainers - they resulted in acceptable hunting accuracy (1.5"-2") but not the pin-point accuracy I considered this cartridge should be capable of.

I've settled on 26.0 grs. of VV N-140 with a Sierra 55 gr. HPBT in the Rimmed version; the Rimless version of this cartridge ought to be able to digest a little "extra". The Sierra 55 gr. SPBT was a runner-up in my load testing as well. Since these are Game King bullets they suit my purpose well without the "explosive" effect of the Varmint type bullets - don't know what you've got in mind for your 5.6x50?

I decided to concentrate my efforts with the VV powders which are more easy for me to obtain here but IMR-4320 & H-4895 loads were promising, too. IMR-4320 especially with the heavier bullets. I'd initially suggest trying these powders which are more commonly available and less expensive than the VV powders in the States.

Have Fun!
