I was born in December of 1952, so no. But I did once own a Model 94 carbine in .32 Special that left the factory in my birth-month!
I haven't yet fooled with any .25-caliber bullets that require a twist faster than 1:10, and probably won't. Any lead-cores up to 120 grains do fine, and even the 115-grain TSX is designed to stabilize in a 10 twist.
Glad you liked the article!
