Has anyone loaded the Speer 46 gr. flat nose bullet in the .22 Hornet.I don't find any data for this bullet in the Hornet, only for the 218 Bee.

They shot good. used H110. I have shot them in a 222 and a 218 bee.
I ended up going to a 45gr v max and a reduced load of bluedot, same in the 222 and use it for turkey

That is one I have never tried in mt Ruger M77 Hornet.

Why a flat-nose?

I thought maybe better impact on short range coyotes

Hornady makes a 45 gr. bullet called the BEE and I shoot it in my Hornet and my 222s. its great on rockchucks, coyotes and Jack Rabbits..
Strangely enogh it has no connection with the 218 Bee but I bet it would perform just as well in the 218 and any other 22 bullet
