Interesting bullet expansion study.

Expansion and penetration comparison of mono, bonded and lead based bullets.

Yep. That is an interesting article. I can confirm that Barnes LRX fired from my 270 this fall did great on a cow elk at 250 yards. The shot was broadside and went through and through. No bullet recovered but it seemed to have a nice wound channel and went through multiple ribs. She only went 60 yards after the shot.

I wonder if the Norma Evostrike would be a good option for those who need/want non leaded bullets but also want fragmentation.

It’s a short range bullet with terrible BC.

96 gr and .292 BC, ouch! I overlooked the specs.

I wish they had fps instead of m/s.

I'm curious about what kind of differance we might see from larger/slower bullets. From my experience, 270s are more of an anomaly than 06, 300 win mag or 7mm.

FPS conversion is listed in brackets under the m/s.

I looked and just plain didn't see it - not at all - musta been skimming too fast. LoL! Now it's gonna stand out like looking at the sun - thanks!

Yup - went and looked... bright & sunny now.

Just so people keep it in mind- bullets fired into water upset/expand more than they do in tissue.

It was a neat way to capture the fragments, can they be reclaimed from gel?

"The 238m distance was roughly the longest distance we could reliably hit the water trap [gallon miilk jug] with the different ammunition" using a "Caldwell The Lead Sled Solo Recoil-Reducing Shooting Rest" to shoot a 270win.

The larger ones can but (I didnt read the whole report so they could have) you can evaporate off the water and recover basically all fragments reguardless of size. It woukd be very very hard if not impossible to do so efficiently.

Despite the papers purpose, all I took away was that federal t bonded lead is the best overall.

Best overall at what exactly?

 

[Warmsy]

Weight retention and expansion size. About halfway through they give the results.

Ok. What do you believe that tells you functionally about what the bullets are doing in tissue?

 

[Pony Soldier]

Looking at the research sources and the result, I think it is more BS to go to copper bullets. Not gonna happen!

That the bullet is creating a larger wound channel, and penetrating further?

 

[Warmsy]

That was my impression, as well.
