I like experimenting with different bullets/powders etc. I enjoy discovering what each rifle does and doesn't like. I'll change bullets every year also just to do something different. Although, I do have a few rifles that have only one load. Now, for example, I'm shooting 150gr RN Sierra's in my 270 win vs the usual 130 gr Sierra BTSP's. They group an inch apart so a small adjustment on the top turret gets me on target with either. From gas lines to bottoms I'm covered. Necessary... No. Fun for me...yes.
