model 10 cyxp

just curious as to what the cyxp stands for. i am ooking for some info on barre twist and what ever tech in fo i can find out about the rifle i can. it is chambered in .223, the magazine doesnt come out and it has a wood stock. i wi be handloading ammo(the reason for the .223 is i sold an ar15 and had several hundred rounds loaded already),and woud like to know if anyone has any luck with something already. i deer hunt with a rem 700 in .308 and have spent several hrs honing that load in. all i know is the savage dosnt like to hold a group with what the ar liked. 55 grain bullet with varget powder cant remember the grains of powder at this time. any help is greatly appriciated.

hornady 77 grain. 23 grains of powder.
Nosler 55 grain 23.5 grains of powder
nosler 60 grain 23.5 grains of powder. all varget. seems to do alright in mine.
out to 300 yards shoots typically .75 could tweek but works good for me...
