Thank you, everyone. A lot of great info here. Also came across the Buffalo Bore iteration of the Barnes TTSX which has some great performance:
I have been using coppers for a few years now and have had good luck with them. I contacted Barnes inquiring about minimum expansion velocities for the following bullets:
30 cal 175 LRX = 1600 fps
30 cal 168 TTSX = 1800 fps
This was with reloading bullet and was told the bullets in loaded ammunition from Barnes are different as least from Barnes. Those tend to be a little slower yet but have a hard time believing that. These speed are to achieve 1.5x expansion and to add 200fps for 2x expansion. I’ve never recovered a bullet so I can speak to actual expansion but I’m always happy with the exit hole and how little blood shot meat there is.
I started loading the 168gr for my 30-06 and found a good fast and accurate load very quickly. Between the 130, 150, and 168 TTSX, the 168gr seemed to be the easy button.
If it were me I’d have the choice between the bullets you listed. I’d shoot 175 LRX, 168gr and the 175gr term assent(still wouldn’t scoff at the others mentioned just trying to keep speeds up) to see which one shoots tightest and maintains velocity above its minimum expansion velocity rating for the distance you are looking for.
FYI the TTSX vs LRX
The TTSX is a tougher bullet and the LRX is made softer of long range expansion. This is seen in the expansion velocity rating. At close range the LRX will loose petals due to being softer.
Most of what I’ve said is information I’ve gathered through communications with Barnes.
But at the end of all that what do I really know?
