I was kinda leaning this way... tho I may try the 73's if I have somebody to back me up if things go sideways. If your looking for 77 tmk's in Canada prophet river had some last time I checked for $65/100. I thought about it but by the time they get to me they'll be closer to $75-80/100. I can buy bullets locally for my .30-06 a lot cheaper than that...I don't have any experience first hand with the 73 ELD-m, however I have used the .223 and Hornady's 55 grain sp w/c for a couple. Neither where particularly close or large bears( both around 100 yards and between 200 and 230lbs). If you're talking eating sized bears I'd use the 55 again and probably will because they shoot well in most .22 centerfires and are cheap and readily available, but I'd prefer a Speer Golddot, Nosler Partition or Swift Sirocco based on my experiences.
If you can find TMK's in Canada at any price currently you're doing well. I occasionally see the 60's but I don't know if they have the same performance of the 69 and 77.
