Best powders I've determined to date:
Alliant Reloder 10x for .223 Remington and Hodgdon H4350 for .243 Winchester. Since these are the only two calibers that I rangefire, I feel I pegged these calibers velocity and accuracywise. Since I recently bought some 105 grain Lapua Scenar bullets, the jury remains out on these bullets until spring warms anew. Since STICKY notations seem aimed at my prescribed loads, I will forgo posting specific loads that work well for me. cliffy
