I'm trying to decide on a varmit rifle. Due to a limited availability of money i am looking at the H & R line of rifles. i am torn between two cartridges and two rifles. the .223 has has cheaper ammo but the .22-250 has better ballistics and power.
Ultra Varmint Rifle

I like this rifle but it's available in .223 not .22-250
Ultra Varmint Fluted

this one is availiable in both .223 and .22-250
i can't decide whether i want to stay traditional and settle with the .223 or go with the secondrifle and get a better cartridge. if ya'll have any experience with these rifles it would be greatly appreciated.
this rifle will be used for general varmiting from ground-hogs and such to coyotes and small hogs.
