I just loaded 8 rounds for my Garand using H4895 (47.5 grains).

Just FYI. The garand being a gas gun is designed to operate in a specific range of pressures. The top end of which is significantly lower than the 30-06 of today. You have to remember that the great powders we have today are more powerful than what they had when the garand was designed and built. Thats why some ammo MFG's actualy have loadings specifically for M1 garands, because they may not function well with todays hunting loads, which are too hot for it. A .308 today is as powerfull as a 30-06 was back when the garand was in service, so a good rule of thumb is to keep your velocities below .308 levels.
Hornadys current manual has a section devoted just to the M1 garand, and for a 150gr bullet using H 4895, it lists a starting load of 43.2gr=2400fps, 44.8gr=2500fps, with a MAX load of 46.4gr-2600FPS..... Your loads are a bit hot for a garand....
