I have found that the BarnsX/Speers Grandslams/Nosler Partitions /Hornadys Interlocks work the best in hunting situations for me, I have found not much bullet weight is lost using any of the bullets I mentioned, bye far the Barns X has the best Mushroom affect, this in tern increases Meplat causing dramatic results to the game animal hunted, The interlocks don't change shape that much, but don't fall apart either, very good in Big bore rifles, I use them in my Marlin 450 guidegun .458, I have found very good results using them on German boars, tough critters,need a good bullet when hunting them, Interlock seem to fit the bill, Partitions work well in my 454 casull, penetration is at the top of the list using the 454 casull/338win mag/300 Savage/308 Win...Grandslams are well known field tested bullets, perform well in the 30 cals & 338win mag, All these bullets had very good accuracy as well. once I find the right bullet I stick with it. Aim small hit small. RAMbo.
P.S. this is a pic of my boar cross sectioned before I butchered it, the .458 Hornady interlock 450 drove through both shoulders without much increase in meplat on the exit, but did a good job on penetration. I dropped that German boar in his steps.
