What is your gun? If it is an old (slow twist) Savage it may not shoot the Sierra or Speer 100 grainers well. Have that situation with a couple of my pre-war 99's. They shoot the stubby semi-spitzer factory 100 grainers great, but won't shoot the longer Sierra, Speer or Hornady bullets worth a hoot. Have to go with the 87 grain flat base bullets in those guns.
If it is a more modern 10 twist, it should be fine with either of those though.
