Thank you all for the advice. I'll go ahead and use it out of necessity. Here's another review I found about the use of federal Gameking 165 grn btsp .308 for elk:
"Wolcott, Colorado Elk. Some may doubt the effectiveness of a .308 as it pertains to shooting Elk...This past weekend was proof that this cartridge is more than sufficient. 16 minutes (For some reason the guide kept time) after sighting in the rifles and driving up to glass our next mornings hunt, we luckily snuck up on a bedded herd. 240 yards, 1 shot, 1 kill. Two days later one of my hunting partners slipped and fell with his .300 WSM hitting the scope on a log. Unsure if the scope was off or not he borrowed my .308...8:01 Saturday morning - 2 more Elk shot and tags were filled for the trip. I love this round. All 3 shots were through and through with large exit wounds. Precision was excellent. 2 Elk dropped where they stood, other made it about 50 yards and dropped."
Entirety consistent with the advice herein! Thank you!
Now if anyone can tell me how to stitch up a sleeping bag using surplus blankets, I'd appreciate it!
