[QUOTE="Eaglet, post: 319535, member: 3756"] My normal 300 RUM load of lately has been 93 grains of Retumbo, 0.015" into the lands using Nosler brass. At long range it's been a shooter for a factory barrel but at 100 yards... you feel like throwing up. Well, I annealed 50 Nosler cases that had been previously shot twice in the same rifle. All 210 gr. Berger bullets had previously been sorted by bearing surface. I decided to see the difference in point of impact from shooting off of a front rest from the bench and shooting from the bench off my bi-pod. After I had seen the difference and was satisfied with the results, I decided to stop shooting paper and shoot other things like coke cans at 300 yards and different things at different distances. It all went very good and I am highly recommending annealing your brass. [IMG]http://i33.tinypic.com/2itr71v.jpg[/IMG] In the pic above, my first three shots from a cold bore, and off the bench using a front rest. The center of the 3 shots went 1.245" high and 0.447" left. The group is 0.692 moa. This is definitely not bad at 100 yards compared to how it had shot in the past. Now it's time to put on my Harris bi-pod on it and shoot another 3 shots. The scope turrets were left untouched. [IMG]http://i36.tinypic.com/30t2b9j.jpg[/IMG] Well, well... This I had never seen with either of my two 300 RUMS at 100 yards, If I had shot all 6 rounds without altering the rests, out of 6 shots 5 shots would have been a big nice one hole. I'm attributing all this goodness to the annealing. What do you think? It was a good practice section, the rifle will shoot from prone position right on also using the bi-pod. On my last group, the center of the tree shots was 0.090" high and 0.121 right. I Think I'll leave it like that! :cool: 0.289 moa isn't the greatest but is good enough for me... I almost forgot, the ES of the chronographed sample was in the high single digits and low double digits... [/QUOTE]
