I have found it necessary to use the max load of TB with plated bullets. It takes more pressure to get good accuracy with plated bullets than with lead. Actually, I have gotten the best accuracy with plated bullets using WW231 and Universal. If they are cheap enough, I would buy them anyhow, as I would use them for fast or instinctive shooting, where they will for sure be more accurate than I am! Plated is all I use, as the indoor range goes over our ammo with a fine tooth comb and a magnet!
No lead or steel!
