RE: 7mm rem mag
trailer yes I have had some experience with both the 140 Fail Safe (Xbullet copy) in my 7mag. And in my Lazzeroni Warbird with 130 Xbullets and just this Sunday I shot 3 does with the new 150 Lazerhead (Barnes' new Lazzeroni offering). ALL deer will go straight to the ground with neck, frontal, rearentry/TX heartshots and direct shoulder shots. But a true lungs only nothing else, is just flatout nearly impossible to drop them instantly, yet on occasion it has happened. Just not nearly enough to call it a "given".
The first doe I lungshot Sunday with the 150 was broadside at 215yds and she ran about 60 yards before piling up. The third doe I shot was at 80yds and also a broadside lungshot. She miraculously ran about 70-80 yds or so before piling up just inside the woods. I know from experience with both the 7mag and my Warbird that when placing those bullets directly into the shoulder it results in LIGHTS OUT where they stand kills. I typically like to break them down and kill them instantly, but knew that I would be keeping these two does for a trip to the processor so I didnt want to poke any holes in their shoulders. In both cases while dressing the deer I noticed that their lungs had been reduced to DARK blackish/purple lumps of Gello so their time "afoot" was quickly lessoning.
What I like about the Xbullets is their incredible toughness. Even when fired near 4k fps like in the case of my 130s, they held together and that was even in one case a couple of years ago when I shot a large buck dead in the shoulder at only 45 yards. If a bullet WONT come apart at 3900fps when hitting two large shoulders, it AINT comin apart ever. Likewise I have shot several lengthwise with that 130 including a doe lastyear facing dead away from me at 308 yards. The bullet entrance hole in her "rearend" (you might call it an emergency hemroid operation!) was not much smaller than the exit hole just ahead of her left shoulder. The bullets simply wont mushroom on whitetails at high velocity. Maybe elk would be another story, but from stories I hear from John Lazzeroni and others that have used them on such critters, the end result is much the same. I go along with the opinions of most professional hunters who do it for a living in Africa... PENETRATION and a bloodtrail that Ray Charles could follow if they dont drop right there!
I have driven bucks lengthwise as well with both my 7mag/140 FailSafe (the last being at 300yards on a south TX deerhunt in 99) where I caught an old 6.5 year old 8pt just under the spine and the bullet traveled under the spinal column to exit about halfway back on the body. The first deer I ever killed with my Sako/Warbird was a LARGE bodied 20.5" 6pt TN "cull" that I shot in the chest at 85 yards and the bullet exited just ahead of his right rear hip. At such ranges I know of no other bullets that would still penetrate full length yet still hold up at close ranges under 3500-4000 fps velocities. I dont like bullets that shed their noses like Nosler Partitions and the like but realize that some guys do!
Now if only Oct will hurry up so I can try these 150 Lazerheads on some WY mulies and "sagegoats"!
