I may of said this earlier or elsewhere, but I have a remington 673 guide gun in a remington 350 mag (used to actually use it as a guide gun). I absolutely love it and wouldn't sell it for a winning lottery ticket. I load it for 220's usually, depending on what I'm trying to kill. The 35 whelen, probably my favorite cal and rife, doesn't have quite the velocity of the remington mag, so it doesn't shoot quite as flat. The 350 rem mag kicks about like a 300 weatherby, which isn't too bad if you've got a good recoil pad and some eye relief. I use an ole 3.5X8X40 simmons scope on it. This is overkill, but I wasn't using it for anything else and didn't want to buy another. I usually keep the magnification on around 4.5. It's a perfect killer for moose, elk, black bear, leopard, mule deer, and anything else soft skinned and in the medium game range. If you don't handload, however, only remington 200 grainers are available, At least that I know of,
I have a .338 Win. Mag. Browning BAR, Excellent caliber in the BAR. It absorbs some of the recoil. Not at all unpleasant to shoot. I would not want to shoot it all day though. ( Don't forget your hearing protection.)
Again, the 673 remington guide gun in a 350 remington mag doesn't have that bad of a kick. Remington used to make another 350 mag that was different than the 673, and it was rumored to kick like a mule. I don't remember whether it was called a 670 etc. However, my 673 guide gun has the felt recoil of a 300 mag (I compare it to my weatherby, but the weatherby is actually worse). It's a light gun and does have a reasonable barrel jump, but it's not even noticeable when shooting it in an off position. I use it for white tail or shotting pigs often because it fits me well and is easy to carry and fire.
When calling coyotes, more often than not they will circle on a target they are
coming into and approach from the downwind side. Presumably they do this in
order to align what they smell, with what they are hearing.
This means that you should always have your downwind side camouflaged and have
an open shooting lane. If the area is heavily covered the coyote could come in
take a look and be gone, with you none the wiser.
