I picked up my 35 whelen dies today, and am picking up the new rifle Monday. I am interested in finding two loads that have close to the same drop. What I am trying to accomplish is having an inexpensive coyote plinking load and then a deer/elk load That hit about the same spot at the same distance. My guess is to find a low velocity pistol bullet load like a 158 gr. HP and a good 250 gr. load.

I know that shooting both loads is the only sure way of finding out, but is there any guidelines I could use, or maybe a software program?

I'd think you'd have some trouble getting them to land at the same zero point, not many rifles will do that with different bullet weights, the heavier bullets tend to land higher on the target, because they are in the barrel longer and the recoil moves the barrel more.

Heck, just shoot some stout 250's and call it good for everything. The 250 grainers will punch right through a coyote and probably won't even expand, but will kill it quick enough.

Slam can you elaborate on your theory of how the heavier bullet is going to be flatter shooting than a lighter one?

Enquiring minds wanna know!
