I'm with JimWatson;
I've played around with junk bullets and I'm in agreement, lifes too short, and good bullets are just a bit more. If your rifle won't shoot MOA or better with 54-55gr of IMR4350 and either a 175gr Sierra Match King or 180gr Sierra ProHunter or GameKing; or 56.5-58.0g of IMR-4350 and either a 165-168gr Nosler B.T., or Sierra or Hornady match or Hunting JSP, or BTSP, it probably won't shoot MOA with anything. (Speer's are good too.....)
Other than the above listed make and wt bullets, I just shoot cast bullets through my '06's. Most of them will make 2moa at 100yds.
The only reason for using Varget, RL15, the 4064's, ect. is with 150gr bullets or less in weight. The only reason for using a lighter bullet and faster powder is for the Semi-auto's such as the Garand that won't tolerate the slower powders. And I don't use the lighter weight bullets in the '06 anymore. If a lighter bullet is called for, I use a smaller caliber rifle......
