Re: 270 Weatherby Loads

I use 72.0 gr of 7828 with a 140 grain accubond. Excellent accuracy and good bullet. Of course start lower and work your way up.

    Thanks. Nosler's manual seems to like about 68.5 gr of 7828 with a 150 grain bullet. I have a ton of 150's around so I may try that first and work up from there. I'd be interested to try the 140gr though. Seems like it could be a good split between the 150's and 130's. I tend to like to find a single load that each gun shoots well and leave it at that. The 140gr could make that simpler for me.

    Ben, I was able to replicate Weatherby Factory 150s w/ R22.


    Weatherby Brass, Federal 215 GMM Primers, 150 Grain Hdy SPIL Flat Base, and ***71*** grains of R22.

    *** This was a quite warm load so, please don't start that High.

    The R22 Load shows no pressure signs and bolts smoothly after firing.

    I was able to Replicate Factory Ballistics w/ IMR7828 but, the Bolt was sticky and primers where starting to Flatten.

    R22 is very close to what Weatherby loads their factory rounds w/. I weighed the Wea. factory charge at 71.5 grains of powder. Not sure what kind Weatherby uses looks like R22 but, I think it may be Norma MRP.

    Good Luck!

    Thanks Reloader. I'll give that one a look. Sounds like your load is similar to mine except the powder. And I'm trying like hell to use boat tails for the longer range potential. But with other guns I have to admit I've always gotten my best accuracy with flat bases. Not sure that's ever made sense to me. I had a 300 Win that shot wonderfully with flat based bullets. But the minute you switched the bullets for boattails the group size would double.

    Depends on if you have the wby throat or a custom throat. If you have the wby freebore throat then the 68.5 grains of 7828 is a very light load. If you have a custom throat then I don't know. With the standard 270 wby you can easily shoot 74 grains of 7828 with the 150 grain bullet and more in some rifles like mine.

    I have found that the big case likes 140 grain and heavier bullets best. But shoot mostly 150's in mine. There is a new 160 grain bullet out that I plan on trying out this year. Go for near max loads all the time.
