Berger 115 25cal

I shoot the 115gr VLD-H in my 250 Savage and my 257 Roberts.
But those two allow me to load it close to the lands, where the VLD seems to like most, in my experience. (0.005-0.010")
With the long leade (throat/freebore) of the Weatherby you may have issues getting the VLD to group best.
A different profile, like their Elite Hunter may do better for you, as they are more jump tollerant.
 
As you said, Unclenick. "Maybe, but maybe not."
I did read the whole Berger manual before i tried loading some.
The stories of Walt were enjoyable!
I did follow the advice from the manual on seating depth for the VLD (close to page 100 IIRC).
Did this for 6 different rifles. One of those rifles being my Stevens 200 in 7mm-08AI, that i used the 140gr VLD-H, now rebarreled to 250 Savage shooting the 115gr VLD-H.
2 Savages, 2 Rugers, 1 Forbes 24B.
All like the VLD up close & personal to the lands. Except for my Mauser in 284 Win. The throat is long enough that i can't even seat a 168gr anywhere close to the lands. I tried back as far as 0.130". No luck.

This year i spent more time at some matches. Almost to the person are saying they seat "into the lands".

I'm not saying that somewhere, someone isn't finding best groups that far from the lands, but would probably be the exception, not the rule.
 
Std7mag,

In recent threads, other members have posted links to The Precision Shooting Blog articles on bullet jump. The first one listed below agrees the conventional range wisdom has currently changed back to being "into the lands" as it had been once long ago. But then they have a couple more articles on experiments reviewed by a statistician for the significance of the results which show numbers more like 0.06" or so off the lands is closer to the universal best. It's bound to be an ongoing topic of experimentation.

These are the three articles:

When I set up my heavy bullet FTR .223 I was prepared to do a series of tests with different "jumps" for JLK VLDs. But when I tried to set .010" to start with and actually got .012", it shot so well I stopped right there and saved barrel life for matches.

Of course not everybody shoots matches. I knew one guy whose sole purpose in shooting was to develop the most accurate load he could. When he had rung the changes and a rifle was doing about the best it was going to, he traded it off and started over. Never to my knowledge shot at a scored target or a game animal.
