Not trying to be an ass, but how extensive with each? What animals and what ranges? What loads? Were they chronograph? What bullets?
OK, you called me on it, I'll reply, from my hunting journals:
Yes, they were chronographed, and instead of list every load for you, sorry, not being an ass, I don't have that much free time to copy everything from my hunting journals and reloading records - just suffice to say that each bullet weight was going the approximate expected velocity for weight/caliber/chambering.
300 mags (I won't differentiate between 300Win/Wby/RUM, etc, because I've never been able to see the difference on game). Bullets used: 165's - Hornady Interlock; 180's - Speer Grand Slam, Nosler Partition, Barnes X/TSX/TTSX; 200's - Nosler Partition.
- 12 Whitetails - 17-240 paces (forgive me, but I didn't always own a laser rangefinder. My pace falls closer to a meter
than a yard, you can do the math)
- 7 Mule Deer - 68- 280 paces
- elk - 3 calves, 4 bulls, 5 cows - 24-365 paces
- moose - 4 bulls - 75-240 paces
- Mountain Goat - 2 u/k number of paces, but I "figured" one at about 175 yards, the other about 250.
- black bears - 4
- grizzly -1
338 Win - Nosler Partition - 210, 225, 250 grain
- Whitetails - 3, 65-100 paces
- Mule Deer - 3, 12-220 paces
- elk - 3 bulls, 63-115 paces
- moose - 2 bulls
- Mountain Goat - 1, figured 125 yards
- Mountain Caribou - 1
- black bears - 2
340 - Nosler Partition 210, 225, 250; Barnes 225 TSX/TTSX
- Whitetails - 4, 47-152 paces
- Mule Deer - 5, 80 paces to a "figured" 300 yds
- Elk - 3 cows, 7 bulls, 90 paces to last two bulls lazered (finally got one!) at 216
yds, and next year at 217 yds (if nothing else, consistent!)
- Moose - 1 cow, 2 bulls, 180-375 paces.
- black bears - 2
- grizzlly -1
My math puts that at a personal total of 19 Whitetail deer, 15 Mule Deer, 18 elk, 3 mountain goat, 9 moose, and one Mountain Caribou taken with the calibers/chambrings in question. Add to that the numerous game I observed being shot with these rounds while guiding for 5 Falls and 4 Springs, and while hunting with friends, and I'd say I have an "extensive enough" personal experience with these rounds to have formed a few opinions. I've never been able to see the difference on game between a 300 mag and a 338 Win (or from a 30-06 and a 7mm Rem mag for that matter, but we're not talking about those ones). I have observed a difference going from either of those rounds to the 340 Wby.
I've shot at least another dozen more whitetails and mule deer, another 2 cows/1 bull elk, and 3 bull moose with 7x57/7mm-08/270/30-06/7mm Rem Mag/257 Wby, but they don't count in this discussion.
Hopefully these observations have answered your questions.
I've observed that a 30 cal 180 grain cup and core at 2500 fps has more apparent killing power than a 200 grain partition at 2500 fps. But I am sure that you will agree that it is a dubious observation. But at the end of the day, they both worked just fine.
You've left A LOT un-answered in your statement above - how many and what animals;what range; angle of penetration; any bone hit or just a double lunger; number of shots?
