Adjusting bullet seating depth for Weatherby rifles

[NeedForSpeed]

I have several Weatherby hunting rifles that I’ve started loading for

My understanding is that they have increased free bore so that the bullet gets a “head start “ or jump before entering the lands. It also is supposedly safer because pressures aren’t as high.

How do you adjust bullet seating depth in this circumstance? Does it pay to bother adjusting bullet depth with this design?​

You turn the seating stem in your seating die up to make them longer, and down to make them shorter.

The adjustment process is the same, just understand you might end up farther from the lands. There is more than one accurate coal for an accurate powder charge weight.

I know how to adjust the COAL with my press. I’m sorry if my question wasn’t worded clearly.

I’m asking if the Weatherby rifle design allows for seating .002 off the lands or if you can only adjust the amount of “ jump” and if adjusting “jump” impacts on accuracy. Or should I just adjust COAL to match Weatherby factory ammo?

Hello, you have a valid question. In other times, I knew of Weatherby owners taking their rifle straight to the gunsmith for a Douglas or Hart barrel to eliminate the freebore and gain accuracy. Having shot some of the rifles, I can say they were capable of outstanding accuracy. However, one did have to adjust loads downwards (albeit slightly) to avoid pressure signs. That said, you can run you bullets out further taking care you don't cause feeding issues due to length or they are so far out that the boat tail is resting in the neck thus compromising neck tension.

Why would the weatherby rifle design have any impact on basic reloading? I.E. The sticky on how to find the COAL for your rifle?

Im not an expert on reloading so I might be out in left field My understanding is the Weatherby rifles are designed to have longer free bore than most rifles Maybe this is incorrect but Soulezoo seemed to think this was a valid question.

Do you mean Weatherby Cartridges? They have a long freebore because they run so much pressure. There is no reason to get .002 off for hunting ammo. I have never loaded for any of the Weatherby Calibers. Just some Weatherby rifles in normal calibers. They had a long throat to accommodate a lot different projectiles.

Why is this less important for hunting ammo? Isn’t it still all about accuracy?

Hunting ammo needs to fit in the magazine.

.002” off often does not, especially in Weatherby chambers.

I've been reloading weatherby ammo for years. Need to know which ones you are loading for. Primer choice is more important than OAL.

Im reloading for a 257 mag 270 win 270 mag and a 30-06
What primers do you recommend?
I started with CCI for mag rounds and Federal for the non mag rounds

 

[918v]

FC primers work better in magnums.

 

[NeedForSpeed]

FC is Federal Figures!?

How much difference in performance? Speed and/ or accuracy?

 

[918v]

They’re hotter which helps to ignite all that slow powder.

On the 257 and 270 weatherby, WMR are best for me. I also use H1000 here. I have mkv actions in both these and can get to 3.30 OAL and feed fine.
