I’d be interested in seeing 130, 140, 150, & 160 grain 277 partitions. It seems SPS has had a lot of 270 Partitions for sale over the last couple of years. I ended up with some in each weight.
As far as the discussion with the different bullet diameters. It seems to me that at one time; as the diameter of the bullet increased so did the thickness of the jacket and perhaps the change in the core. That is a 338 bullet would be built “tougher” than a 308 bullet. I don’t think that’s necessarily true now.
Bullet technology has changed so much. Compare what we have for choices today to what was available before Nosler designed his partitions.
You apparently haven't read my posts, or book chapters, that mention how Partitions definitely do vary depending on caliber/weight.
In fact posted one on this subject on this thread, last evening.
