460 Weatherby - Old Barnes Bullet Load Data

[jstanfor8]

Thanks !

Try H4350 about 112 grains to start.

112 exceeds the max of 110 for a 416--start with 102 grains

118 gr of H4350 compressed is about the max but, depends who ya ask.

Thanks! I found some load data on Hornady RN 500 grain that appears to be very similar so I think that's a good starting point. I'll let you know how it goes--I'm targeting 2450 muzzle velocity for 500 grain Cutting Edge Safari Solids for hunting Ele this fall and these Barnes RNs will be for practice and to just use them up.

Cutting Edge .458, 500 grain, Safari Solid

I had to chuckle when 'plinking' was mentioned.

My favorite plinking rifle is a .510 Wells Express which is made by necking up the .460 Weatherby to take .510 bullets. Practicing could be a little debilitating when use full house hunting loads, not to mention expensive. I use the Woodleigh 440 grain SN which ostensibly is a 'black powder' bullet. Moderate amounts of powder made this a reasonably pleasant day at the range or just plain fun shooting up some rocks on the desert. When chasing T-Rex across the desert I usually load the Hornady DGS 570 grain for some deeper penetration...

Great caliber!

I had a 450 Dakota for a while. It's the twin of the 460 wby. Same load data. Shot a few Buffalo with it. Sold it.

In no universe would I plink anything with that gun!

Have fun!

Looking to see if anyone has any load data on Barnes .458 500 grain Round Nose FMJ--Barnes no longer makes these bullets and I have a box I want to load for some plinking at the range.

Loaddata.com....lots of info....Barnes #3 and # 4 editions...what powder do you want to use...I load .460 bee

I'm using H4350 at the moment for these old Barnes 500 grain RN FMJ got 2,486 muzzle velocity at 112 grains over the weekend. After these, I'll have to look for an alternative 500 grain "practice" bullet. I'll be hunting elephant this fall with 500 grain CE Safari Solids.

Aim for an even 2500fps as that is a sweet spot in the MarkV rifle for cloverleaf accuracy. 115 grains of H 4350 or Win 760 will get you there.

112 grains won't achieve factory spec's with the .416 Weatherby. I have owned 3 of these rifles and loaded for them extensively.

114gns of H4350 chronographed at 2850fps with the 350gn Barnes. IMR 4350 achieved the same velocity, 10fps less actually, but 118gn IMR 4831 got 2918fps, Original 4831 proved too slow burning with 120gn only reaching 2730fps. With H4831, 116gn chronohraphed at an even 2800fps and for a light load, 95gn of IMR 4320 reachec 2570fps.

Again, .30/06 powders worked well in the .416 Weatherby case.
Hope this helps.
