I just ran your load threw quickload with a 22" rifle barrel,
40gr Serria HP, with 9.8gr is 2410 fps @ 31600psi.
45 gr speer Sp with 9.8gr is 2362fps @ 34600psi,
And as a hornet owner, your rabbitograph damage, isn't as tore up, as mine tend to be,
I run 11.5 gr of littlegun with a SPP primer CCI500, under everything, 40 v-max and 45, 46 gr Speer, at about 43000psi and 2900 for speed. this is possibly a bit hot for the 45gr, or 3.5gr trail boss, with the 46gr for a quite load, about 1500fps.
there is room for improvement on your loads if you want to run a bit faster and flatter.
10.5gr 2205, will take you to about 2600, at 39000psi, with a 40gr Serria Hp.
but a powder change to littlegun, Cfe blackout, N120, 4227 will likely give you 3-500 more on speed.
Littlegun really ups the performance in the .22 Hornet, quite a lot of info online if you search, lots running 12gr, but i think this is a bit hot,
I have just received a box of 40gr Fox copper bullets, to try in my Hornet, I've loaded 6 with my std load,
