anybody have any load recipes for a rem 260. I have some imr 4350 powder and some H4350 powder also. I've got a box of 123 grain sierra matchking bullets that are supposed to be here tommorrow. any of you guys load for a 260 rem using this combination and where would be a good place to start. looking maybe at starting at 43 grains of powder and going up .5 grain increments. any suggestions? thanks.
