Re: load data for 250g AB and .340 Weatherby?
If you have a mk 5 wby action and standard wby freebore you may be able to shoot this load. Just start around 87 grains 7828 then work up and see where it goes. CCI 250 primers worked best in it. My best load with the 250 gets 3060 fps with 6 fps extreme spread in a 5 shot group with the 250 gameking at .565 BC. This is out of a 28" Hart barrel 1-10, with the wby freebore. I have taken elk at over 1000 yards with it. It is super accurate. Also the 210 scirroco with a .507 BC shoots well. 3285 fps with 5 fps spread.
Predictions are difficult, especially when they involve the future
