The 250 shoots a .257 bullet,the same as a 257 Roberts,25/06,257 Weatherby,etc.
That caliber of bullet is a deer killing machine,as well as antelope,mule deer,and all kinds of varmints.
It comes in bullet weights from 75gr-120gr,and just about every bullet mfg offers bullets in .257 if you reload.
Check the barrel length on the Savage.A 24" barrel is the minimum that I would suggest for any .257 caliber,with a 26" being a great match for it.
Most factory guns come with a 22" barrel,and don't shoot as well as a longer barrel.
Barrels in .257 caliber will get hot very fast,and a sporter taper will be extremely hot after a couple shots.My heavy barreled 25/06 gets so hot after 5-6 shots,that you do not want to touch it!
