Many of the same caveats on reloading for the .30-06 Garand apply;
1. Always FL re-size
2. Don't try to get more than 5 firings out of a piece of brass
3. Seat primers slightly below flush with the case head
4. Keep cases trimmed below max OAL
5. If available, use CCI No34 MILSPEC primers. Otherwise WLR, CCI LR, or Rem LR work OK. Avoid federal primers as they have softer metal in the cup
6. Use the correct propellants. IMR4895 was MILSPEC for the 7.62 NATO. All of the following are within the correct burn rate for the Garand and will generate the correct pressure at the gas port; IMR4064, IMR3031, H4895, BLC2,and W748. I have found IMR4895 and IMR 3031 to be the most accurate in several 7.62 Garands, which is no surprise as both were used for military 7.62 match loads.
7. Use bullets in the 150-168gr range. The Hornady 150gr FMJ is very accurate for a non-match bullet and can be bought in bulk
8. Work up loads IAW a recognized loading manual.
