[QUOTE="BrentM, post: 996542, member: 61747"] I am amazed at some of the speeds guys are getting. I can not shoot 58 grains of retumbo without destroying my brass in any of the 3 6.5-284's I have. I needed to be at 57 or less. Best speeds I could do with a load that didn't put ejector marks on the brass is 2920-2940. Most safe loads came in right around 56.5 grains with 210m. This is 24" barreled rifle. Lapau brass. I went to a 28.5" and switched to Nosler brass and had to settle at 56.5 with 210's. 215's put marks on the case. That produces around 3025 with averages being 3020. I ordered new lapau brass and need to restest and see if I can get back to the 57-58 level without beating my brass to crap. I am happy with 3050 fps and low impact on the rifle and brass and keep accuracy in the .5 or less mark. I verify all my drop data in the field at 1000 yards by the way. However, I did find Retumbo produced better speeds for me then H4831 as well. I have not tried 7828 or 1000 yet [/QUOTE]
