I don't know the regs for any other states, but the minimum caliber for Muleys in Wyoming is .250 so you will have to leave the .243 at home.

Just read MT doesn't have any, surprised WY won't allow .243 for mule deer, I think CO minimum is .243

All depends on idea of firearms setup.

Lighter rifle with a standard scope my ideal caliber for trajectory using quality bullets with upper end Ballistic coefficients would go to the 270 win using 130's and the 300 win mag using 165's. Up to 600 yards those setup ups are dang hard to beat on trajectory and guess work in the field on hold overs. Any of the WSM's would work as well.

Heavy rifle with bullet compensating scopes would go to the 264 win mag and the 7mmSTW or 7mm rem mag. The 6.5 and the 7mm are near impossible to beat when using the heavier bullets with very high BC bullets. Shooting past 600yards these calibers preform like a dream. 6.5 140grain bullets/ 7mm 168 grain bullets and above.

There are some fast calibers out there but the price of the cartridges can leave you not wanting to spend a lot of time on the range. The RUM's, Lazzeroni's and Weatherby's can cost anywhere from $3 to $6 a shot. That's expensive range time. If you have the extra money no problem.

Umm...

Last I checked the minimum in WY is .230- .243 and 6mm cartridges are legal.

Id venture to guess it doesn't get any more open country mule deer than the flat farm lands of eastern CO. We use all kinda of ultimate. No one gun suits every circumstance. Range and accuracy trump raw power.

7mm STW or 7mm RUM. Good luck.

I was stand to be corrected . . . looked it up again and here is the 2012 regs 'Wyoming statutes authorize the use of a firearm that has a barrel
bore diameter of at least twenty-three-hundredths (23/100) of an inch and
is chambered to fire a center-fire cartridge not less than two (2) inches in
overall length, including a soft or expanding point bullet seated to a normal
depth'

Few years ago my brother and I bought two Winchester Featherweight 7mm-08 Blue barrels,
We dropped lots of games, deer, black bear, elk, crows...
We reload and lots of our recipes are amazingly accurate, they are definitely tacks drivers
Here's an example of an average 3 shot group, not the best nor the worst.

Last fall we went through a lot of inclement weather, fortunately it pay back.

Even if I did a lot of maintenance on it, dry it out and oil it every night, got some rust pitting here and there:

I’ve then Ordered last December a new one, Stainless tough.
Well, just FYI I just send back today my new Winchester Featherweight STAINLESS 7mm-08: POOR accuracy .
148 rounds through it, reload, factory, redone the bedding, lapping compound; name it.
Average 1.8 inch 3 rounds.
Even switch scope to make sure.
Gunsmith from the service center told me it was not unusual with the Stainless barrel.
Some may think: you got what you pay for! Wrong call.......
Here’s an example with factory rounds

I got the same rifle blued, sold it for inclement weather, shame on me.

The blued one was a tack driver, I rely on that when I’ve decided to move for the SS.
Here’s another example from the blue one:
First round was the fouling shot, there’s 4 rounds in the grouping.

I really don’t know the next step, what they are going to do, hopefully the problem is the barrel, easy fix, but I do worry a lot fell some pressure and uncertain about her future.
Very disappointed, also have a Winchester 30-06 Ranger, and an XTR 7mm RM, so pleased with them.

Winchester Model 70, 270. Bought mine in 1974 and it has served me well. It is still my go to gun and wouldn't part with it. Killed a big mature muley at 450 yards with it.

Hornady superformance 130 gr interbond. (prior was known as Light magnum)

I'd have to take a backup rifle too. First choice would be my Mod70 F.W. in 6.5x55 with 2-7x Redfield using 129gr Hornady Inter Lock's.

Backup would be my mod 700 in 25-06 with a 3-9x Bushnell Banner, very old Banner. It lives on 117gr Hornady Inter lock's.

I say these because these are what I have. Could be a whole lot of different cartridge's.
