say i want to shoot a .243 for deer and varmints. can i sight the gun in so i can shoot 100gr. and 55gr. without ajusting the scope everytime i switch up the hunt.

big difference in 100 grain and 55 grain.100 grain will drop way more than 55 grain.hmmm just use 100 grain on both d

Just shoot the 85 grain BTHP from Federal. It will work great for both deer and varmit. It is what I use for deer and it is a wicked bullet.

I shoot Wenchester 100 gr. psp for what ever I shoot. it works great on them all. if you want one for both that doesn't drop very much , try the 90 gr.

You could sight in with a 100 grain mark your elavation dial. Sight in the 55 grain and mark dial. Then when you switch back to either you'll just have a couple of clicks to get there.

Depends on how much different they shoot. If they shot pretty close windage wise I would just sight in with the lighter bullets then see how it shoots with the 100 grn bullets. Chances are out to 200 yards there will not be much difference, at least not enough that will matter on a target the size of deers vitals.

I have been told though that most .243's do not like the 55 grn bullets, just to light and fast for the twist rate I guess. So you may have to go with something heavier anyway just to get it to shoot well.

I'm thinking of doing the same thing, but I am just going to split the difference and use a 80 grn or so bullet.

The trajectory for a 80 grn bullet out of a .243 is pretty similar to a 55 grn bullet out of a 22-250 out to 300 yards. Plus it would carry more energy do to the heavier bullet.

would the 80gr. be big ebough for deer? and small enough fo coyotes?

I use 100 gr. Remington PSP Core Lokt's for everything from jackrabbits to whitetails to wild pigs. Works great on the bigger stuff. Makes a bit of a mess out of jackrabbits, though... Should work quite well on coyotes.

im looking to save my first fur and after that it doesnt matter if i make a mess of the fur.

Isnt shooting part of the fun???? You can record the clicks and just shoot one verification shot at the change....
