I understand the subjectivity of this question, and all the infinite variables that contribute to the final outcome. However, in your personal experience, at what distances has your ballistic tip bullet of 150 grain or greater, failed to completely pass through a white-tail, or equivalent sized game positioned broadside at the time of impact? This is asked without any discernment or whether or not bone was hit. I understand the ballistic tip is not best used for close proximity, high speed impacts, so lets set the minimum distance at 100 yards. All comments welcome.
In general a Nosler BT and most other conventional expanding bullets for that matter actually penetrate better at the lower end of the velocity spectrum than they to do the higher. I know that inverse relationship sounds wrong, but the expanding bullets when shot at higher velocitieswill generate a larger, shallower cavityinstead of deeper penetrating wound cavity. The KE is released much quicker at higher velocities and this actually reduces penetration.
Solid non expandingbullets willalmost alwayspentrate further at higher velocities, as most hunter would haveexpected of all bullets.
Yes, you are correct. As i said in my first post, close proximity, high speed impacts aren't what this bullet was designed for. That's why I suggested the minimum yardage be 100 yards so that the velocities have a chance to drop allowing for better penetration. Thank you for your reply.
depends on what cartridge its fired from
the 7mm-08 does very well at about all ranges
the 280 will run the 140 out the muzzle at 3000 fps
the 7 RM will do 3200 so it better be around 150-200 yards
a 7mm STW will put the 140 downrange at 3500+ so you could fail tp penetrate a deer at the 400 yard line
my 7mm Allen mag sends 150's downrange right at 3700 fps so its running the same velocity as the 7mm-08 does at the muzzleat just under 500 yards.
so guys are always slamming the BT, its expected to perform the same on all game from a MV of 2800-3700 fps, don't think thats possible.
RR
bear, mine has a 26" 9 twist lilja, it runs 140's out at 3550 fps. it will do 3602 fps but the bolt lift just starts to get heavy so I backed it down 2 grains.
RR
yeah the 9 twist 4 groove lilja's are tight and fast, I even called sierra techline during load developement cause it was running so fast it scared me. had never put over 80 grains is a case before so it intimidated me.
It is a mark bansner smithed 700, that he designated the ultimate rifle 1 (UR1), the darned thing will run 160's at 3340 fps.

Damn, RR, you like your deer pills moving FAST! But then again, you're one of the elite few people I've heard of that can credibly take advantage of that much speed!
I personally think that the Nosler BT was designed with standard velocity and the "slow" magnum cartridges in mind, not the 100gr+ powder burners that have become en-vogue of late. If you like shooting a big magnum, and short shots are as likely as long, my personal choice would be to use a much stouter bullet like a Barnes TSX or Nosler partition (and others).
As far as the debate over the killing power of hunting grade BT's on deer, the line you see most is "I shot the deer and it ran 40 yards before it dropped, but the bullet didn't exit so what's wrong with it?" The answer is, of course, not a darn thing. The key is that the deer died, and did so quickly. If the deer is dead inside 75 to 100 yards, who gives a rip if the bullet made an exit hole?
