This was an interesting observation from Broz on the 7mm 195 killing elk from this thread;

"But since I spent last fall killing elk like a mad man (70 elk taken total) and the 300 win with a 215 Hybrid @3035 and the 7-300with a 195 @2950 were the two rifles use most for the first of many kills, let me offer some real world long range hunting results. PS, both rifles loaded to max with equal pressure signs.
First, to the OP, you are cheating your 300 win with the 210 VLD. It is no doubt that the 195 is one of, if not the best bullets for external ballistics there is for a 7. So lets offer the same to the 300 win and feed it a 215 Hybrid with a much higher BC than the 210 VLD. It is only fair to compare hybrid ogive to hybrid ogive right? Plus the 215 Hybrid with its shorter bearing surface than the 210 VLD will actually get more velocity than a 210 with less powder. Been there done it over and over.
Now lets go kill elk. I mentioned the 300 win and the 7-300 were the two most used rifles during a good part of last season here. This included a pre-season management hunt, all season long. And a post-season management hunt. Some nights we even had these two rifles side by side with a different hunter on each rifle while we waited in the blind for the elk to enter the hay field. Here are the results. The 215 Hybrid will out kill the 195 in a way so obvious after about a 15 or 20 elk taken with the 7 I put it away. The 300 with a 215 , not once needed a second shot to dispatch the elk. The 7mm, several needed a second shot. Now, add in the real world possibility of a less than perfectly placed shot and the advantage in terminal performance of the 300 with a 215 becomes even more evident.
This I feel is a great comparison. Why?
1: Because all this info is real and happened.
2: Same parent case were used.
3: Same powder were used
4: Same barrel brand and length were used same number of lands and groves
5: Repeated results were studied with several witnesses
6: I personally field dressed about 50 elk and documented the terminal performance, wound channels and shot placements myself
7: Optimum bullet used for each chambering
8: Both with the same muzzle brakes and barrel contour.
Since I just happen to have both of these rifles in my ballistic app, with drops documented to a mile and confirmed. Lets compare the real world external ballistics.
7-300 win with 195 Berger @ 2950
800 yards 10 mph 3:00 wind
dial up 15.9 moa right 2.6 moa
impact velocity 2150 energy 2000
300 win with 215 Hybrid @ 3035
800 yards with 10 mph 3:00 wind
dial up 15.0 moa and right 2.8 moa
impact velocity 2141 energy 2188
7mm takes .2 moa less wind (one click)
300 has 1 moa less drop (4 clicks)
300 arrives with 188 lbs more energy.
I used 800 yards because the OP was about at that distance for his comparison. And 400 to 850 were where we took all of these elk. But if you want to go further the same trend in results will only magnify the advantages of each.
So I offer these documented results for those who are trying to decide between the 7 and the 30. It will always boil down to personal needs. But if elk are ever going to be in your freezer, under equal conditions, the 30 cal will out kill the 7 all day long."
