Anyone have any factory 270 Weatherby 130ttsx ammo that could give the COAL/CBTO measurement?

As every rifle is slightly different, you may be best served by starting out about 0.050" off of the lands, and adjust from there. Barnes generally like being pretty far from the lands! Which makes it pretty sweet for those that have magazine length issues!

I know that's not a direct answer to your question…..but, I hope that it was somewhat helpful! memtb

Not sure if I can get to lands with a wby chambering with free bore. I wouldn't feel comfortable with so little bullet in the case.

Well, while I'm meddling in your business, you have plenty of case capacity to go with a heavier, longer bullet…..offering higher BC's, more sectional density and better long range potential! Just a thought

When I was loading a 270 Win for my wife…..I went with 150's for better performance on larger big game. Far less case capacity and less velocity than you will see with your Weatherby!

I'd be seriously looking at the Barnes 155 LRX….. crunch some numbers with it…….it may surprise and please you! Starting velocity means little…..except at closer ranges! memtb

All of my factory 270 Weatherby ammo has had short OAL compared to what I load them at.
I let my rifle's magazine length determine the OAL I use. You have .376" to play with, if your mag box is 3.4", load to that, if it's a Mark V, load to whatever has enough bullet in the case.

I don't understand why you would be wanting factory ammo specs?

Cheers.

Mainly curiosity.

What is determined to be enough bullet in case?

This topic was covered a while back on this or perhaps another forum. I believe the consensus was, that with a Barnes…..one band inside the case neck was sufficient!

A search might get you into that conversation. memtb

Well, this is a controversial subject, just as what length a neck should be…
What @memtb says is correct, but many think ONE CALIBRE is minimum, however, I do not believe this to be true.

Cheers.

A lot of people I talk with on FB state that the factory ammo is a great place to start in OAL or CBTO. Especially if someone is having difficulty finding a great handload.
Factory ammo in my 6.5x300 is so good I don't need to reload. But **** what is the fun of that.
But I do exactly as you stated i always start with max mag or mag box and work my way in.
I have found a good bit of people asking how did they find a good load for their weatherbies. Most common answer and fix was try factory oal or cbto and adjust from there.
