Reloading 270

[blackops]

I've recently purchased the Barnes TSX .277 150gr. I've been looking for quite some time and can't seem to find the load specifics. I went to Barnes website, but it seems to be down until the 1st. I have found some similar charges, but nothing exact. I was hoping someone had a little experiece or could help me find a website that will list the load data. Below I've listed my "ball park" load information. Nothing accurate. Anyone have any helpful information? Also, I am using Hodgdon H4831, Winchester Brass, and CCI BR-2Primers. Thanks.

Barns book

Sorry, I don't have a Barns book.

Because of the monolithic bullet engraving harder than lead core bullets, the max loads for other 150's is not applicable.

You might want to just invest in the book.

What are you huntin' wth them, elk?

I will be using these bullets for pig and deer primarily. I know the 130gr will do the job. I want to try the 150's though. I tried the Nosler E-Tips and my rifle simply just doesn't like them.
