I have two Hornets, a Ruger no. 3 and a Kimber 82 Super America. I use either R-P or W-W brass snd CCI BR-4's in both.
The no.3 likes 11.7 IMR 4227 with the 45 Speer spitzer. For squirrels I've used the old Speer 55 fmj ( a semi-point) and 9.5 grs of IMR 4227. Another reduced load is with either the 50 gr. Speer or Sierra Blitz with 11.5 grs of IMR 4198 (compressed) for about 2250 fps.
For the Kimber I use 11.7 grs of WW 680 (discontinued but I've got a couple of pounds) and the 45 gr Speer
