I have never used a lubrisizer as i have been casting for about 3 months. i have been using 45-45-10 for the few i have loaded so far. i have been looking at the rcbs and older lyman 45 for a while to get a really good deal but usually they pop up when the bills are due. sizers i would need to buy are .452 and .358. .452 For now because that's my only mold for now.
