I have some questions on the sizes for my .223 rounds im trying to make. Im using the speer load book #14. In it it gives me my measurements for my cases. max case lenght is 1.760" trim to lenght 1.750" max cart. oal 2.260" now i dont have a automatic trimmer, so im trimming by my hand tool. Am i getting the case sizes between the trim lenght and the max case lenght or does every shell have to be 1.750" and when i go to set my bullet depth im having difficulty getting it set to exact 2.260" im getting it to 2.599" 2.261". can it be the one thousandths over or under the coal? I know im asking alot of questions lately but I just wanna get it right. dont want nothing to happen when i go shoot. and at the same time im learning my sons learning too so just want to be safe you know.
