I used to participate in high power matches with a Garand. Nowadays it's just for funsies, but I still love the old military firearms. I have a modern replica of the 1853 Enfield in .577 caliber, a 1903A3, a M1917, a M1 carbine, Russian SKS, AKS, STG58, AR-15, and just purchased a SMLE No4. Mk1/2.
You gain a new respect for the soldiers of WW1 and WW2 after getting kicked in the shoulder sending a few dozen 150 grain .30-06 projectiles downrange.
It is amazing how accurate these old rifles are - with iron peep sights at 500 yards!
Congrats on the 03A3. That is an American icon!
