Interesting that you chose to quote 180gr bullets, when the thread is about 165gr bullets. Bullet length is critical to BC, and as bullets get longer a full boat tail is a larger factor in BC. So of course the lead nose full boat tail bullets catch up to the plastic tip semi boat tail bullets at maximum bullet lengths. Thus it's a bit disingenuous of you to quote 180gr bullet parameters to counter my assertion, which referenced 165gr bullets.
Not according to the bullet parameters on their websites:
Code:
.308" 165gr
Nosler BT .475
Interlock SPBT .435
Seirra GK SPBT .404
.308" 150gr
Nosler BT .435
Interlock SPBT .349
Seirra GK SPBT .380

150s and 165s are by far the most popular bullet weights fired through .308 and 30-06 tubes in North America. 180s in 308/30-06 are overkill for most anything but elk/moose, and have limited range due to low velocity. I've never hunted either, but if I did I'd leave the 150 BSTs at home and use 150gr Federal Trophy Copper (Barnes TTSX) for the superior penetration.
Of course not. Because most people simply don't have the required talent, practice, equipment, and/or training. But do note that this is the Longe Range Hunting forum. As such, it's assumed that individuals on this forum likely possess these prerequisites.
Long range doesn't necessarily correlate to an unethical kill. In my case it's just the opposite. In 25 years of white tail hunting all my 200+ yard shots (80%+ of my shots), have resulted in DRT kills. Converserly, I've had a number of animals get up or languish after a bad first off hand shot at 150 or less, often running. All were put down fairly quickly with a follow up shot.
I simply won't take a 200+ yard shot unless I'm able to deploy the bipod, and I rarely take such shots at running deer. The 400 yard doe kill was one of only a couple exceptoins. Wish I'd had that one on video--Nosler and Federal would have paid handsomly for that--a 400 yard kill on a doe moving at 20-25mph. Odds are I'll never have that opportunity again.
So in my case, all of my 'unethical' kills have been short range engagements, while all of my long range engagements have been single shot instant kills.
