The 250 Savage is a great deer cartridge. I have one in a pre64 M70 unfortunately the rifles originally chambered in it had a 1:14 twist rate IIRC to stabilize the light bullets used to get the advertised 3000 FPS. With very careful hand loading I can get just over an inch at 100 yards with a 100gr spritzer bullet.
I should sell it and buy a more modern rifle with a quicker twist rate but what fun would that be??
