I have used the .240W with 90X (back in the 90s) for exotics like Axis and coyotes, all under 325 or so. It was perfect. I have a church member who has used it for decades here in Utah with the 95 partition for deer/elk, up to 400yds or so. He holds tight behind the shoulder, gets his game. As always, it depends on your will-power...if you have busted your hump for a week in the hills, and you finally get a shot at a hard angling bull, over 200yds away...could you pass it up? If not, then no, the .240w will disappoint you. If you are after hay field cows, late season, you will have better shot opportunities and then yes, it will do swell! However, if its the only rifle you have and you would rather spend your money on the hunt itself, go for it! Life is too short to agonize over it, just have a ball!
