Having lived about half my life in Tucson (about 30 years) and having to move here to NY to care for very old parents, I can't wait for the day I can go HOME. Around here life is full of 4 letter words such as SNOW, COLD and RAIN.
Anyhow, back on subject.. I obviously use a #1 in 45-70. Most everything I shoot seems to do prettey well, including cast bullets. I think some of this my be because of the weight, thickness and stiffness of the barrel.
My "worst" groups would still be minute of critter.
