Colorado raised their price on cow tags this year, Wyoming NR apps are already in but maybe something on the leftover list in June.
Your .270 will work nicely, though I would prefer the partition, properly placed. If I had a cartridge of more hp I’d bring it…..but, don’t go out and buy a new rifle for one hunt!
The across the counter tags in Kolorado has great merit. Be very careful with leftover tags in Wyoming….there’s generally a “VERY” good reason they are “leftover”!
Good Luck with your decision and your hunt, should you make your hunt! memtb
