After the turn of the century, probably 2002 or 2003, during NRA week I was squadded next to a WWII veteren who was shooting a Garand in 30-06.
Because of the rotation I was always in the pits when he was shooting, but he was shooting expert class scores. The HM I was with, who had been with the Gentlemen, said the vet had a match barrel installed on his rifle then built the match rifle up from there by himself. Hardly anyone was shooting 30 caliber at the time and he was about the second shooter I ever met at Perry who shot a match Garand in 30-06. He was shooting a Garand because that is what he was familiar shooting.
I picked up one of his cases and he marked the head with felt tip. The next day I handed him the case, when we were going through roll call on the firing points, and ribbed him about worrying that anyone would mistake his cases for their own.
We were all very proud of him and he had to be in his late 70's. My memory was 77 years, but I could be wrong about that. We on his target cheered him when he shot well, though he could not hear it. He shot the full four days which when you add in the heat and target pulling is physically exhausting, so he was a real trooper.
