I have a Ruger 10/22 with the BX-25 25 round magazine. I'm going through various 22LR ammo to see what my gun "Likes" and what it doesn't. I've read somewhere that each rifle will have it's own likes and dislikes where a paricular round is concerned, but wasn't sure how valid that is. Mine appears to hate everything CCI. (I've tried the subsonic rounds, and the CCI mini-mags, both stick so bad in the mag that removing them by hand is a chore. They just won't feed from it.) They really like the Remington gold. I've bought some Thunderbolts to try, and a small box of Winchester Super X. Before I go out and buy 1 of each little box of ammo, what do you guys suggest as a good rule of thumb? Plated rounds only? No magnums? No sub-sonics? Winchester? Federal? Remington? Does CCI make anything that it will throw? Would I have better luck getting a stock 10 round mag? Other/better Mags to try? How often (If ever) do you dismantle the BX-25 magazine to clean it? What should I focus on if/when cleaning it?
