I am useing 76 gr. of rl22 and the 150 gr. accubond with great success in my .300 win mag sendero heavy barrel. Shoots .5 in @ 100yds. I don't know what it cronos ,I don't have one . I'm strictly guessing at about 3200fps . If any body has cronographed this load I sure would like to know. I caught wind and weather conditions right one day and did a 4 inch group at 600 yds. The gun has a 4.5 to 14 burris ballistiplex on it that helps a lot . The rl 22 also works real good on 165 smk's at .5 in. at 100yds. folks tell me the rl22 can differ in lot but I have not seen it yet. Try it I think you will like it and the 150s. Sometimes western NE requires some LR shooting on deer . It does a good job on them .
