Meaning Speer "plinkers" or something else? I've got a few of those to try (some day!) in my Remington '03 and have been wondering if they would work in a Carbine. Speer #12 lists using them with an OAL of 1.625" - Bob
I think if you have the right magazine, such as a single-stack, they will feed. I shoot Mauser bullets at OAL’s down at that length. Never have been moved to purchase the screwdriver bits.
