Can’t find the massive 6.5 bullet test threads but don’t know if these were in it or not.
Comparing the 120 Nosler BT and the 129 Hornady SST, which one of these is tougher?
Please note I’m not asking BT vs SST in general, as I know both of these types of bullets have undergone changes over the years, but specifically looking for comparisons between the current 6.5 120 and 129.

For background, I don’t handload. I’ve been shooting BTs in my 260 but see that Hornady loads the 129 SST. I don’t know why they won’t load an IB or GMX for the 260 but oh well. If the 129 SST are tougher than, or at least about the same as, the BTs I may give them a try.

Also, the 7mm 120 NBT gets great reviews around here due to its thicker jacket. Out of curiosity, how does the 6.5 120 NBT compare to it?
Has anyone ever sectioned the two for a side by side comparison?

Thanks in advance
