Our 270 WSM seems to be coming to the end of its top-performance barrel life. (Christensen Arms Carbon Classic) It was a great rifle that shot well for us and harvested a lot of game over the years. I was considering changing it to something more efficient but would like to use the same action if possible. Any wisdom and experience to lean into this? 6.5 WSM? 6.5 SAUM? 7MM WSM with faster twist for 180's?
270 WSM rebarreled to something more efficient?

Fast 1:7.5" twist 6.5SS and shoot the 150SMK/150 Matrix/156 Berger/160 Matrix.

I'm assuming you reload? If you want efficiency, then one of the Sherman Shortmags would be perfect. 6.5, .270, 7mm, 300, or 338, any of them would work.
6.5 - 140 ~ 3250 fps
.270 - 170 ~ 3000 fps
7mm - 180 ~ 3000 fps
300 - 215 ~ 2950 fps
338 - 250 ~ 2800 fps
Pick your poison. If you don't want to go that route, there is nothing wrong with rebarreling to another .270 WSM since your already set for it, just this time give it an 8 twist and shoot the 170's if you want to get the best long range ballistics out of it.

At this point I'm not set up to reload. Once I can back away from some of my work obligations, I want to do that. As of now, we get that done by Copper Creek. Lots of good ideas here 
maybe more to come…? Thanks a lot
maybe more to come…? Thanks a lotThe 170's sound interesting. Anyone on here have experience with them in a 270 WSM? What kind of velocity can be expected? OK with a 24 inch barrel? Mag length required?

7mm WSM would give better performance.

7 saum, not a second thought. Can get factory loaded 160 accubonds that will kill whatever you want.

In a WSM the 170 would need a decently long box, but a smith could always install a bainey 3.1" box for ya. Performance would be awesome. But, I don't know of any factory ammo loaded in it.
Best factory ammo option may likely be a 300 WSM. Followed by either a 7mm WSM or SAUM. WSM will give better performance, but not a huge margin.
Has the import restriction to the US lifted? Unless, I missed it, Matrix used to have it on their website. Hopefully, trade is now open again.
