Vhit N550 or N150 for 130gn copper 270 Win?

[Nkawu]

I am struggling to find any load data for 130gn copper mono metals with either N150 or N550. I have these in stock in decent amounts hence the requirement. I am interested in either Barnes 130 ttsx or the similar weight peregrine VLR4. I have experience with both in my 308 but not in my 22” barrelled 270 Win.

If anyone has a load data resource I could study before taking the plunge I would be most grateful.

Thanks.

I’ve had great results using N160 and Barnes ttsx not the 130 grn instead 110grn in my .270
Use the search function on here plenty of load development been published.
Suggest you look for post by forum member @takbok

Hi thanks a lot for this. Is the stated powder load in the top right the max load equating to the pressure curve below?

It is, the powder weight is also listed in the bottom middle
