You lost all of those animals to inadequate expansion?
If you want to be a smart ass, do your thing. You can do a search on here about the bull that npaden's son had a hell of time finding a day or two after it was shot with a 140 e-tip from a 7-08.
For the rest of the folks reading this:
Here's what I know, they are easy to work up loads for and shoot well, at least for me.
I've caught 4 of them from my 7 RM at 3000+ fps, this one is the best expansion I got out of those that I recovered (furthest on left) compared with a bunch of 140 accubonds at 2850 from my 7-08.
Frontal view of the same bullet:
Same bullet compared to a dime:
All the others were pass throughs and exit holes were probably the size of a nickel/quarter, compared to the usual 50 cent piece sized exits I get from 140 accubonds. Blood trails were less than stellar from every animal I shot with them. Which is about a 180 degree difference from the blood trails I get with either 160 AB's out of my 7 RM or 140 AB's from my 7-08.
Which, IMO/E, could be a real problem for people that aren't experienced or even for someone that is experienced during dry conditions. I want blood trails and good ones, not picking around looking for drops of blood every 5-10 yards.
Seeing how little expansion I got out of the etips pushing them probably 300-350 FPS faster (at least) than I could get out of 7-08, I would recommend not using them at MV's less than 3k. Even at that velocity I would use caution at much beyond 350.
But hey, what do I know?
