I've been loading 210 VLDs in my 300rum Sendero factory rifle. After trying to shoot them 1 mile I decided to go to the 230s. So my goal for now, is to be able to hit my 12"x16" steel plate at one mile with come consistency. I figured I would post this project on here to see if the info can help others or for others to critique my process. The rifle has a little over 300 rounds through it with the 210g VLD's going about 2980fps so I believe it still has some good life left in it. At one mile I was hitting all around the plate but never made contact. Yesterday I started my load development by finding the max I feel comfortable loading the 230's with Retumbo. The 210's shot best around .050 off the lands so this is where I started with the 230's. Worked up from 87 to 93 and feel comfortable at 92. Could have gone a little more but I would like the barrel to last as long as possible, and I feel that 3000fps +/- should accomplish my goal. At 100 yards I was impressed with how it is shooting so far. The top four shots are 90 to 93 grains. I have done ladder tests with other rifles but with the last one I loaded for, I found the max I felt comfortable with and it shot great there so thats what I went with. I plan to do the same here, so I will see how it shoots at 92 grains this evening or tomorrow evening hopefully.
