Best powder to use with .270 SST's

A lot of good powders out there. You need to watch for pressures and if your $ watching, each powder might give similar speeds but with different amounts of powder. You need to decide on a bullet, research for several powders and their load specs, buy several small amounts of each powder, load all powders at lower limits to get similar listed speeds and see what your rifle likes best. Then slowly start loading higher loads with your chosen powder, while watching for over pressure signs and never go over max load listed. This is all about getting the best performance with the safest load. Welcome to the fun and wonderful world of reloading !
 
Here's a cross section of some Hornadys' & Noslers (not my pic, but helpful).

First two red-tipped rounds are SST & Interbond respectively. The second in from the left is an Interlock SP, while the remaining are Accubond, Ballistic Tips for comparison.

You can see why the SST is prone to fragmentation & not a good choice due to its' thin wall design.


Based on those cross sections, I can see how the SST would be a weaker design. However, the Interlock seems to have a very similar construction to the Accubond. I don't want to skimp on bullet quality, but I also don't want to pay a fortune for them either. I want to get into reloading to save money rather than overpay for factory stuff. I do realize that my savings will not be huge, but I also realize that I will(hopefully) be able to build a quality bullet that will perform well and be tailored to my rifle. So that is why I am considering mid priced bullets instead of high end mono metal.

Nice .. shot..
 
Okay, my bad. The Accubond is the one with the white tip. Nothing like the Interlock, oops. If the second bullet is the Interlock what is the first bullet?

The article where I grabbed the photo from didn't mention what it was, possibly a Nosler Partition (?)

That picture answers many questions; thank you.

Aside from length, shape and tip, the SST appears to be an Interlock in jacket/core construction. The first mystery bullet might simply be a heavier bullet than the second Interlock SP. Whatever it is, I'd very much like to see more cross sections particularly to visually see the differences between target bullets and the various hunting rounds as well.
 
If it's a Partition, where is the partition?, I can't see it. It's called the Partition for a reason.

Yes, i erred there. Had a few windows open researching Partitions, must've been on the brain when I replied/typed..

Google is your friend there. I simply typed in SST Vs Interbond and found that picture
 
Use solids for hunting. You might think they're more expensive than factory, but if you look at the price of the solids loaded ammo, it's really not. SST is more a varmint bullet imho. Cheaper for practice though.
