Only way to chase off the competition.Got to love the guys that like to **** in peoples Cheerios.
Yep total BS...yet again the caliber changes to a larger case ...cause it's a ridiculous claim.Im pressure he was disputing someone's comment.
Whatever you say captain expert. I disagree with your logic and reread what he wrote in detail. He goes onto explain it later in the post. By the way it's his thread, he's the OP. Chill out!
Who knows maybe it was a 30-378 Bee. I'm sure @nralifer will explain since you're calling him a BSer.
Those who can't face reality.. often do not.What a waste of breath and energy. Love the squirrel comments. That's entertaining!
I called the guy who actually did the load development for the shooter who shot the Elk. I assume you have never used our bullets to hunt with, so your conjectures on how well they expand or their BC do not derive from primary experience. Be that as it may both guys were hunting together, and the load developer, who lives in the area of the Wasatch mountains called the shot for the shooter. They were at about 8900 ft, measured the distance with a laser range finder and the station pressure with a Kestrel. He recalls the station pressure was 21.50, the MV of the developed load was 3007 fps average, temp was between 45-50F. The gun used was a 300WM with a 26" barrel. The photo shows a JBM calculation of the shot. Actually the terminal velocity at impact calculates out to 1881fps (1532 ft-lbs). The bullet hit the Elk in the high Rt shoulder and dropped. The bullet went through and was not able to be recovered. Apparently a Black bear tried to get on the carcass within 5 minutes but they managed to scare it off. Your statement that "high in the mountains would help", minimizes the effect of altitude and atmospheric pressure on bullet resistance. When you run the calculations using either the stated altitude assuming a 1ATM pressure at sea level or the actual station pressure they very very close. The calculator corrects the sea level pressure for the altitude specified. Those are the facts as accurately as I can report them. The fundamental fact was the Elk was killed with one shot at a distance well beyond 1000 yds and at an impact velocity well above we know is needed to expand these bullets.Total ********! ...And that is fact.
Run the ballistics the 195 gr would have to have a muzzle velocity of 3250 fps on and average day to get 1770 fps at 1225 yards. High in the mountains would help but cold weather would make it worse ...but no 308 can reach that velocity, with 195 BD with a given G7 BC of .345 which must be employed after 1000yd to even be accurate information over the G1 BC of .675
I can reach 2856 as a standard load with .360 G7 BC with the 200 gr SMK or max 2950 with hybrid cases and a 30" 8 twist barrel, but even run those at 2910 fps for general work with the powders available and tested so far, and it's definitely not Leverevolution...and that is the best 308 load for bullet velocity and energy down range, and that would get you 700 to 800 yds and still meet the criteria of 1500 ft lbs and 2000 fps. Even the normally available big magnums are hard pressed to meet that criteria at 900 yds, as very few would make 2000 fps the minimum expansion velocity of most bullets. Copper even harder to get to expand if it's designed for high velocity. And the bullet is 1.650" long according to the site they state will stablize in a 10 twist, if it does it will be marginal and not hold its BC for longer shots and becomes unstable. Plus I like the exactly 1225 yds, it's usually not like that ...clue #1. And he's out of parameters with velocity and energy. So I could shoot an elk at 1225 with a 22 LR accidentally hit the brain and it would fall over proclaiming tbe 22 LR a 1200 yd elk cartridge. I like the 308 Win but it ain't magical. We are supposed to be improving it not overstating its general usefulness and current potential.
Your data is incomplete. You need to show what the terminal velocity likely was, and that is a function of BC and atmospheric conditions. Also what medium did they impact. Furthermore, the inability of the bullets you show to expand says nothing about our bullets.All these bullets have a 3000 fps muzzle velocity. Impacted at 950 and 1000 yds. None expanded.
The first two are Nosler BT one of the most explosive bullets up close but at 950 yds one tip broke off and the plastic tip still intact on the other...known as bullet failure in the hunting community. But they explode inside the 100 to 300 yd range, with a 3000 fps muzzle velocity. Just, The facts, and testing must be done if one is to extend the range of his 308 to see where bullet failure begins,... 450?, 500? And where it's inconsistent. Hunting and sniping are two different endeavors.

The second photo is of a 375cal 300 gr SBD2 gel test showing the MV of the shot into the 10% gel which expands at roughly the same speed as the 195 gr 308 cal bullet in question. Sorry, but I don't have a photo of the 295 gr 308 cal bullet specifically, but the ogive on the 375 cal bullet is a bit fatter.
Finally, your comment about the 195 being marginally stable is simply not true. Stability increases with decreases in atmospheric pressure, increases in ambient temp and humidity. The third pic calculates the stability under the conditions of the hunt. Unfortunately the fourth photo showing the stability at sea level standard conditions would not download, but the stability factor is 1.379 which is still adequate. The operating principle is that anything that decreases medium density, in this case air density, INCREASES stability. In both cases the bullet is adequately stable. If you think you could kill an Elk at 1225 yds with a single shot from a 22LR, go ahead and try. It would be impressive.
So it's not a 308 a winchester as I had suspected. And it still doesn't fit the prameters of discussion with 2000 fps and 1500 ft lbs.I called the guy who actually did the load development for the shooter who shot the Elk.

So what 308 bullets expand consistently well at 308 velocities, say 3000 fps at 900 to 1000 yds? I'll try a few in a couple of barrel lengths, say 22" and 30" you provide load data, to see if it fits the criteria. Except for certain subsonic bullets, at a certain point below 2000 fps most will fail to expand consistently and violently as needed. The barely expanded copper bullet is unimpressive, and doesn't fit full violent expansion needed, just slightly better than no expansion, more like a wadcutter, than a sharp point.Your data is incomplete. You need to show what the terminal velocity likely was, and that is a function of BC and atmospheric conditions. Also what medium did they impact. Furthermore, the inability of the bullets you show to expand says nothing about our bullets.
