I've shot about 100rds of cast through my garand so far. Cleaned it today and found one tiny spot of lead on the gas piston and two tiny spots on the gas plug. I finally figured a load that cycled my garand action. 39 gr of pull down IMR 4895 under a lee 170gr I tried the recommended 36 grs and it would eject the brass but not strip the next round or eject the clip.
