I have a .223 build that I'm in the process of doing.

1. What twist rate should I consider using for this build? I will be using it for varmint hunting as the primary role for it. Second I would like to be able to use it as a back-up deer rifle.

2. Bullets; I have over 12,000 Hornady 55Gr. Spire Points, #2266 along with several 1,000's of the 77Gr., 80Gr.

3. The 1/10 twist is the standard. 1/9 should handle the 75Gr. & 77Gr. but I think my need for the 1/8 would be my best bet. 1/8 should handle a good selection of bullets.

Thank you all in advance for all the reply's.
